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

Address info flag AI_*

Flags used in "hints" argument to getaddrinfo()
Note: Under Linux these values may be different

`AI_PASSIVE = $00000001;`	Socket address will be used in bind() call
`AI_CANONNAME = $00000002;`	Return canonical name from DNS in the first ai_canonname (Cannot be used with AI_FQDN)
`AI_NUMERICHOST = $00000004;`	Nodename must be a numeric address string
`AI_NUMERICSERV = $00000008;`	Servicename must be a numeric port string
`AI_ALL = $00000100;`	Return both IPv6 and IPv4 addresses
`AI_ADDRCONFIG = $00000400;`	Only return addresses if a global address is configured (IPv4 or IPv6), loopback addresses do not count as global.
`AI_V4MAPPED = $00000800;`	Map returned IPv4 addresses to IPv6 address format
`AI_NON_AUTHORITATIVE = $00004000;`	Allow both autoritive and non authoritive return addresses (NS_EMAIL only)
`AI_SECURE = $00008000;`	Obtain result using enhanced security only (NS_EMAIL only)
`AI_RETURN_PREFERRED_NAMES = $00010000;`	Return preferred names (NS_EMAIL only)
