class SOCKS4aServer extends SOCKSServer
This class processes SOCKS4a protocol requests, supporting both IPv4 addresses and domain name resolution (the "4a" extension). It validates requests, maps IP addresses to domain names when configured, and forwards connections to I2P destinations or outproxies.
Handles CONNECT commands, rejects unsupported BIND commands, and provides proper error responses. The server integrates with I2P naming service for destination resolution and supports security restrictions on localhost access.
