Can you explain the history of 8080 port and why that’s somewhat of a default
The number 8080 is often used as a default port for web servers, such as Apache Tomcat and Jetty, and application servers, such as GlassFish. It was originally chosen as a default because it is higher than the well-known port numbers (0-1023), which are reserved for specific services in the Internet Assigned Numbers Authority (IANA) list, and lower than the privileged port numbers (1024-49151), which are reserved for system processes.
The use of port 8080 as a default for web servers and application servers dates back to the early days of the web, when it was first becoming popular to host web content on personal computers. At the time, port 80, the default port for HTTP traffic, was often already in use by other services, such as Gopher, which was a popular information-sharing system in the early 1990s. As a result, web developers needed to use a different port for their web servers, and 8080 was a convenient choice because it was available and not reserved for a specific service.
Today, port 8080 is still widely used as a default for web servers and application servers, but it is not the only option. Other common ports for web servers include 8000, 80, and 3000.
I hope this helps! Let me know if you have any other questions.

Can you explain a few of the Internet Assigned Numbers Authority list and in doing so explain what a Port is in the context of what a server is, all using a waiter and a restaurant as a metaphor
Certainly! The Internet Assigned Numbers Authority (IANA) is responsible for coordinating the maintenance and allocation of various technical Internet protocols and codes, such as port numbers.
In the context of servers, a port is similar to a specific table at a restaurant where a waiter would take orders and serve food. Just like how each table at a restaurant has a unique number, a port on a server has a unique number as well. When a client (such as a computer running a web browser) wants to request information from a server, it does so by sending a message to the server on a specific port number. The server can then listen for requests on that port and respond accordingly.
There are several well-known port numbers that are reserved for specific types of services, such as port 80 for HTTP and port 443 for HTTPS. However, there are also many other port numbers that can be used for custom or specialized services.

Give me some examples of Internet Assigned Numbers Authority protocols that would make sense to a layman
Here are a few examples of Internet Assigned Numbers Authority (IANA) protocols that you might be familiar with:
Domain Name System (DNS): This protocol is responsible for converting human-readable domain names (e.g. www.example.com) into numerical IP addresses that computers can understand.
Simple Mail Transfer Protocol (SMTP): This protocol is used for sending email messages between servers.
File Transfer Protocol (FTP): This protocol is used for transferring files between computers over the Internet.
Hypertext Transfer Protocol (HTTP): This protocol is the foundation of the World Wide Web and is used for transferring web pages and other content between servers and clients (such as web browsers).
Secure Shell (SSH): This protocol is used for secure remote login and command-line access to servers.
I hope that helps! Do you have any other questions about IANA or these protocols?

What is the IANA number for DNS protocol
The Internet Assigned Numbers Authority (IANA) has assigned port 53 to the Domain Name System (DNS) protocol. When a client (such as a computer running a web browser) wants to request information about a domain name from a DNS server, it does so by sending a message to the server on port 53. The server then listens for requests on that port and responds with the requested information, if it is available.
In addition to using port 53, DNS also uses a number of other well-known ports for various purposes. For example, port 22 is often used for secure DNS (DNSSEC) transactions, and port 5353 is used for multicast DNS (mDNS).
