Avoiding DNS Conflicts - IONOS Help (2024)

How to resolve DNS issues? ›

Log in to IONOS and select the Domains & SSL tile. Next to the desired domain, click on the gear symbol in the Actions column and select DNS. Click the Reset domain link under the Adjust Destination button.

DNS conflicts are caused by overlapping DNS records. If DNS records overlap, the conflicting DNS records will either not at all or only partially function. If you add a DNS record that conflicts with other DNS records of an active service, a warning will be displayed.

Generally, we recommend a TTL of 24 hours (86,400 seconds). However, if you are planning to make DNS changes, you should lower the TTL to 5 minutes (300 seconds) at least 24 hours in advance of making the changes. After the changes are made, increase the TTL back to 24 hours.

Navigate to All Programs > Accessories and select Command Prompt. In the command line interface, run ipconfig /flushdns . You should receive a confirmation message once the DNS cache is flushed.

Your changes are effective immediately at IONOS. However, it can take up to 1 hour for the change to take effect externally due to the decentralised structure of the Domain Name System.

To Flush the DNS Cache:

Type 'ipconfig /flushdns' in the Command Prompt, and press Enter. 3. The user has now flushed the DNS Cache and will receive a message that they have successfully done so.

One of the most common issues that causes DNS errors is the TCP/IP settings. You can check these by going to the control panel, and choosing “Manage network connections.” You can then look in the Local Area Connections properties, and look at the IPv4 and IPv6 properties.

How to check DNS is resolving or not? ›

Best practices for ensuring good DNS performance include using providers that support CDN, considering the use of self-managed DNS, increasing DNS TTL parameters, and using CNAME flattening or DNS prefetch. A combination of these approaches can help eliminate slow DNS problems and help improve your bottom line.

The TTL field limits packet lifetime in computer networks and IP packets to prevent routing issues. The TTL should be set high enough to allow packets to reach their destination while avoiding too many hops.

Standard network commands, or utilities, like traceroute and ping, use TTL to reach the host or trace a route to that host. Ping is used prior to using traceroute to determine whether a host is on the network.

Time To Live, or TTL for short, is the sort of expiration date that is put on a DNS record. The TTL serves to tell the recursive server or local resolver how long it should keep said record in its cache. The longer the TTL, the longer the resolver holds that information in its cache.

The basic process of a DNS resolution follows these steps: The user enters a web address or domain name into a browser. The browser sends a message, called a recursive DNS query, to the network to find out which IP or network address the domain corresponds to.
