Domain name servers are an important part of the DNS system, handling queries regarding domain names so thatinternet users can locate websites. When someone types a domain name into their browser, their computercontacts the domain’s nameservers, which send back the corresponding IP address in response.
This same process works for anything that functions in the DNS, including:
-
Web browsers
-
Email
-
Chat
-
Connected appliances, and more
Your DNS server handles queries to your domain. Once your site is set up for business, and you’re attractingvisitors, you want to make sure it’s available to them. Most domain registrars include a free DNS, whichcovers a host of basic functions. Paid premium services offer guarantees regarding site security and uptime.
Domain name servers might not be something you’ve considered before, but any site owner should be informed onhow these servers affect their website. Your choice of name server can greatly affect your websiteperformance and most importantly, your visitors’ user experience.
This article covers everything you need to know regarding how the DNS system impacts your site and if apremium approach is appropriate for your needs. We answer the fundamental questions, including whetherwebsites benefit from paying for a service that’s available for free.
Read on to assess if, like many powerful websites, you could also benefit from a paid DNS service.
What is a Domain Name Server
You might be wondering what DNS is, let alone why you should care about the ins and outs of it. In short, thedomain name system, more commonly known as DNS, translates human-readable information (the domain name,website and any other internet resources) into the addressing protocols (IP addresses) used by computers tonavigate and locate information online.
It's far easier to remember words and phrases, such as Netflix and Google, over 84.21.044.1, forexample. This sounds complex, but the basics of DNS queries are actually quite straightforward.
Each website has a corresponding nameserver. To view a specific website, you must connect to its nameserverto retrieve its IP address and any related files. For example, when someone types Techradar.com into theirbrowser bar, their browser will seek to translate the domain name Techradar to an IP address. This processinvolves asking (or querying) the DNS to locate Techradar’s domain nameserver. If Techradar’s nameserver isnot accessible, the visitor’s browser won’t be able to find the IP address to display the website.
In the case that you have a domain without a domain nameserver, when people search for your site they willget a ‘site can’t be reached’ error because there is no host to your website.
Setting up DNS
Nameservers point your domain to whoever is in control of its DNS settings. This is usually the same companythat you registered the domain name with. For example, a domain name registrar such as Namecheap can alsohost the website and take care of the domain’s nameservers. If preferred, it’s entirely possible for yourdomain to can take hosting from one company and point it’s nameservers to another.
Most DNS providers assign a minimum of two DNS servers per domain. Once a domain is pointed to thenameservers, the website will be live within a matter of hours. For more information about your domain’sname pointing and nameservers, it’s recommended that you contact your hosting provider.
How Nameservers Affect Domains
Domain name servers are important for online businesses because they affect speed, redundancy, and security:
-
Speed of Queries - Slow websites are irritating to web users, and slow site speed can affect search engine rankings (DNS makes up a massive part of load times).
-
Redundancy - This relates to uptime, meaning how readily your website is available to visitors. Using a redundant system means that if one DNS fails, another is available.
-
Security - A secure DNS greatly reduces the severity of attacks on your resources.
The degree of speed, redundancy, and security guaranteed by a nameserver depends on the service levelagreement (SLA) offered. The SLA outlines the levels of service that can be expected between client andprovider.
Let’s take a closer look at the typical services offered by a domain nameserver:
Speed
Speed plays a huge role when it comes to choosing the right DNS provider. Fast DNS hosting providersoffer a minimal delay between the DNS lookup and time to first byte, indicating how responsive a webserver is.
Optimal DNS hosting is when a provider has multiple servers in various geographic locations so thatthey are more likely to be closer to a visitor. When DNS queries travel a shorter distance lookuptimes and web address resolution speeds are faster.
Performance is a huge factor when running a website. For this reason, the best DNS providers investsignificant time and go to great expense to set up global networks of servers. This setup allowsquicker response to DNS queries regardless of an Internet user’s location.
Redundancy
When people browse the internet and open a URL only to encounter a ‘website not found’ error, manyusers will naturally assume that the site no longer exists. However, 30% of the time, the problemwith accessing the site is related to a DNS issue where the nameserver has failed. If you arerunning a business, you should avoid a situation where you have a single point of failure.
This is where secondary nameservers are helpful. DNS hosting providers let you configure secondarynameservers. It’s just like storing a backup of your computer files on an external hard drive on thecloud. If your computer is damaged along with your files, you can quickly get them back.
Similarly, it can also be beneficial to use multiple DNS providers. The most common method is toconfigure separate providers for your primary and secondary DNS. In this instance if your primaryserver fails, your computer will immediately query the secondary server until the correct IP addressis returned. If your primary DNS provider fails and your website doesn’t have a secondary DNS, yourwebsite will be unavailable.
Security
The levels of security included with DNS servers vary between providers. It's important to be awareof the risks connected with insecure nameservers before choosing. An insecure DNS makes your websitevulnerable to attack from hackers, specifically DDoS attacks.
Distributed Denial of Service (DDoS), attacks occur frequently, targeting websites all over theworld. A successful DDoS attack on your website means that you will be unavailable for businessonline, or, even worse, visitors could be pointed to a malicious IP address where they may hand outinformation they otherwise wouldn’t have.
Protecting your DNS is one way you can make it harder for hackers to launch an attack on yourwebsite. This is why having multiple DNS providers is essential.
Types of DNS Servers
Most, but not all, domain name registrars offer nameserver services when you register a new domain. Domainowners have the choice of which hosting they prefer. The specifications and limitations vary between thevarious types.
Self-hosting
DNS can be self-hosted by running DNS software on generic Internet hosting services.
Shared hosting
is when a number of hosting accounts are located on one server, with some sharing the same IPaddress. These types of plans have limited features and resources, and are not recommended forsites with high resource consumption.
Managed DNS
this is a service that organizations use to outsource DNS to a third-party provider for reasonsof simplicity. Another company sets up and maintains their DNS servers.
Virtual Private Server (VPS)
Is where one server acts like a dedicated server. However, a physical server is partitioned intomultiple servers, each with their own operating system. VPS users have more control over theirnameservers. Each receives a specified share of the resources of the physical server, and arecompletely isolated from each other, meaning they do not affect each other if they experienceproblems. Webmasters implement VPS to cut the cost of a dedicated server.
Dedicated DNS
Dedicated hosting providers tend to be the most powerful option, they are faster and morereliable because they are designed for hosting DNS query traffic and nothing else.
Free DNS
Covers the basic DNS requirements for most websites.
Premium DNS
Includes premium features to keep your site secure with guaranteed uptime, better support andmore.
Free DNS
If you've got a tiny personal website for something like holiday photos to share with friends and family, andyou don't expect it to grow and don’t care about uptime, free hosting is the right choice for you. There’sno shortage of free DNS hosting providers to choose from, and each has a variety of different features.
Some come equipped with firewall policies, filtering, and rate limiting and blocking to help prevent DDoSattacks. The majority of free services include facilities to manage the records of your domain zone andtypically offer Dynamic DNS.
If yours is a casual site or simply something you are doing for fun and it’s not the end of the world if thesite is down for a couple of days, free DNS services should work for you. On the other hand, if it’s acommercial site that is driving your whole business, then you should choose a service that will safeguardyour site with better support and uptime. These are the key differences between opting for free DNS andgoing for a premium service.
Premium DNS
Every commercial website should use premium DNS to guarantee they are both safe and available to theircustomers. There are distinct advantages of paying for a DNS: improved site availability, fasterperformance, and minimal security gaps.
Premium DNS involves pointing your domain to premium nameservers and setting up your records on thesenameservers.
These are the typical features you should expect from premium DNS services:
-
Many premium DNS service providers offer Dynamic DNS (DDNS). DDNS automatically maps internet domain names to IP addresses, allowing you to access your home computer from anywhere in the world. Unlike standard DNS, which only works with static DNS, DDNS is designed to work with changing IP addresses, which is a good fit for home networks.
-
Management interface - A well-configured DNS dashboard lets you manage and make updates to your DNS easily online, instead of going through customer services to redirect your DNS using different record types, for example.
-
Reporting - Advanced reporting is available with premium services, including analytics that report the source country and record type for queried hostnames.
-
Administrative Control - Admin controls let you delegate administrator privileges with ease.
-
Two-way authentication - Protect your domain with two-factor login authentication.
-
DNS templates - Save time by applying DNS templates to the domain names in your Premium DNS Dashboard. This is useful if you are managing multiple websites.
-
Fast Performance - Redundancy - Guaranteed service level agreement for DNS resolution between 99-100% with paid DNS plans.
-
Queries per month - Premium DNS services guarantee domain resolution on millions of queries per month.
-
Close security gaps - Hackers can use your IP address to point to a malicious IP address to trick users into divulging important information and sometimes even money. Premium DNS hosting provides an additional layer of security for your website and thus additional protection from hackers.
-
DNSSEC support - Increase your domain name security with managed DNSSEC. Premium nameservers provide support and security for top level domains to protect them from attacks. Hackers have been known to infiltrate the DNS lookup process, directing users to deceptive sites for password and account collection, for example. DNSSEC is employed to protect domains from any vulnerabilities in the DNS system.
-
First-class customer service. DNS can get a bit tricky, so having professional support as and when you need it is invaluable to a smooth running website.
-
It is easy to use. Experts and beginners will find the interface for managing their nameservers simple to navigate.
Paid DNS services offer advanced features to manage your DNS, combined with a higher level of support andfaster loading times. If you want super fast IP address resolution, you need a premium nameserver.
The fact of the matter is, extremely quick websites leave a good impression. People are impatient online. Ifyou can shave a few milliseconds off the time it takes for people to discover your site via DNS, you mightsee some marginal gains.
Fast speeds aren’t only to impress your site visitors; you’ll want to impress Google with your site’s loadingand availability. If your site loading times aren’t up to scratch, your search engine rankings andsubsequent click rates could take a hit (DNS capabilities make up a huge part of site load times).
Paid DNS Considerations
The argument goes that if your site is relatively small and you don’t expect it to grow, there's no reason touse a premium DNS service these days. Several of the high-end providers will offer a free tier anyway.
Consider this; the value of going premium can be likened to the value of the site/domain you are running.Even if you don’t have a high-traffic website, you’ve got a website. It’s likely that you want to make sureit’s safe and always online.
Most site owners think premium is only necessary for large corporations that need the performance andsecurity enhancement premium services offer. Because hackers target everyone these days, it’s worthconsidering a paid DNS that fits your budget to avoid the hassle.
Another huge benefit of premium nameserver services is the scope for configuration. You might want morecontrol over your nameserver setup and don’t want to have to to email support because you don’t have fullaccess to your nameservers. Premium allows you to make basic and advanced configurations yourself, withsuperior assistance, if required.
How to Choose a Premium DNS Provider
All well-known premium DNS service providers will offer comprehensive solutions to your DNS needs. However,we’ve noticed some areas they all fall short on. Some so-called premium service providers offer little byway of premium features aside from reporting, which doesn’t make a fully premium service.
We can’t speak for every DNS provider but can guarantee that Namecheap offers a complete array of premiumfeatures. We’re best known for domain registration services, but we also offer free and premium DNS hosting, featuring Dynamic DNS touse as your primary DNS service or as a backup.
In 2016, we introduced a 100% uptime service that guarantee websites are available 100% of the time.
Multiple DNS Providers
It’s entirely possible to have multiple DNS providers to eliminate the possibility of a single point offailure. This is commonplace with powerful websites because if one server is taken down by a maliciousattack, they can always resort to the secondary server. This saves face in an online service community basedon security and reliability.
How Much Does Paid DNS Cost?
The overall cost of DNS services depends on a few factors: the size of your website; resources required; thekind of traffic the hosting would respond to; which security measures are needed; and so on. The good newsis, premium DNS is generally very affordable, with packages ranging from a few dollars to around $60 peryear.
The price point Namecheap offers with its Premium DNS makes a great argument for even the smallest ofbusinesses to deploy this service. For a few dollars a year, our PremiumDNS comes at a price any small business or individuals canafford, at markedly better value than the rest of the competition.
Switching to Premium DNS
You can always try free DNS hosting and then decide whether you need premium. If you do decide that premiumDNS is the best option for your domain, it takes only a few simple steps to switch your services from theunpaid version. Once you’ve decided your domain could benefit from premium servers, think about your futureneeds to assess which plans match up with your requirements.
Just make sure that you check the SLA and examine the specifications of each plan, as well as comparing thespecs to the needs you anticipate for your domain. You want to make sure your bases are covered!
It’s also entirely possible to use premiums DNS from a third-party, as in, not your domain name host. To usepremium DNS services from elsewhere, you need to re-point the domain to the required servers.
