Discovered that GoDaddy’s cPanel provides built-in email support with up to 100 accounts.

Technical Notes: For SSL certificates, I needed to update the DNS hosts file hosted on GoDaddy servers for the domain. This was a good opportunity to better understand DNS systems, especially after discussing DNS steering in a recent technical interview.

Watched videos to deepen my understanding of DNS SOA, Name Servers, and the history of DNS. The videos helped clarify the importance of these concepts in the broader context of networking.

Structure of Domain Names

Domain name data is structured hierarchically. At the top level is the root node. Every domain on the Internet is a member of the root node. Under the root node are top-level domains like .com, .edu, .org, .uk, .ru, .biz, etc. Below that are domain names such as webmonkey.com, navy.mil, or country code extensions like .co.uk. Anything beneath that is a subdomain or host. Subdomain names can be layered to a total depth of 127 levels.
