Error return codes from gethostbyname() and gethostbyaddr() (when using the resolver).

For this reason the codes are based at WSABASEERR+1001. Note also that [WSA]NO_ADDRESS is defined only for compatibility purposes.

Authoritative Answer: Host not found
`WSAHOST_NOT_FOUND = GlobalSock.WSAHOST_NOT_FOUND;`
`HOST_NOT_FOUND = GlobalSock.HOST_NOT_FOUND;`

Non-Authoritative: Host not found, or SERVERFAIL
