DNSResolver

DNSResolver is a simple client-server application designed to resolve IP addresses to their corresponding domain names and vice versa using DNS lookups. The server listens for incoming connections and processes requests from clients, returning the primary domain name, IP address, and any associated aliases.

Features

• Simple client-server architecture
• Resolves IP addresses to domain names and aliases
• Resolves domain names to IP addresses
• Provides informative responses to clients
