Error return codes from gethostbyname() and gethostbyaddr() (when using the resolver). Note that these errors are retrieved via WSAGetLastError() and must therefore follow the rules for avoiding clashes with error numbers from specific implementations or language run-time systems. 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 = (WSABASEERR+1001);`
`HOST_NOT_FOUND = WSAHOST_NOT_FOUND;`

Non-Authoritative: Host not found, or SERVERFAIL
`WSATRY_AGAIN = (WSABASEERR+1002);`
`TRY_AGAIN = WSATRY_AGAIN;`

Non recoverable errors, FORMERR, REFUSED, NOTIMP
`WSANO_RECOVERY = (WSABASEERR+1003)`
`NO_RECOVERY = WSANO_RECOVERY;`

Valid name, no data record of requested type
`WSANO_DATA = (WSABASEERR+1004);`
`NO_DATA = WSANO_DATA;`

no address, look for MX record
`WSANO_ADDRESS = WSANO_DATA;`
`NO_ADDRESS = WSANO_ADDRESS;`
