How Does DNS Work?
DNS operates through a network of servers that communicate to resolve domain names into IP addresses. The process involves:
- Recursive Resolvers - They initiate DNS queries.
- Root Servers - The first step in resolving domain names.
- TLD Servers - Handle top-level domains like .com, .net, etc.
- Authoritative Name Servers - Provide the final IP address for the requested domain.
