Domain Name System (DNS)
The DNS is a hierarchical naming system that translates human-readable domain names into IP addresses that computers use to communicate.
Root Level
Managed by IANA, contains 13 root servers worldwide
Top-Level Domains (TLDs)
.com, .org, .net and 1,500+ other extensions
Second-Level Domains
The registerable part: "example" in example.com
Subdomains
Optional prefixes: "www" in www.example.com
Domain Resolution Process
When you type a domain name, multiple systems work together to find the correct IP address.
1. Query Initiation
User types domain name in browser
2. Recursive Resolution
DNS resolver queries root servers
3. TLD Resolution
Root server directs to TLD nameservers
4. Final Resolution
Domain nameservers return IP address
