The Windows Sockets gethostbyname function gets host information corresponding to a hostname.

struct hostent FAR * gethostbyname (

const char FAR * name
);

Parameters

name

[out] A pointer to the null terminated name of the host.

Remarks

gethostbyname returns a pointer to a hostent structure. The contents of this structure correspond to the hostname name.
The pointer which is returned points to a structure which is allocated by Windows Sockets. The application must never attempt to modify this structure or to free any of its components. Furthermore, only one copy of this structure is allocated per thread, and so the application should copy any information which it needs before issuing any other Windows Sockets function calls.

gethostbyname does not resolve IP address strings passed to it. Such a request is treated exactly as if an unknown host name were passed. An application with an IP address string to resolve should use inet_addr to convert the string to an IP address, then gethostbyaddr to obtain the hostent structure.

Если у тебя Delphi6 то покапайся в компонентах Indy
или зайди в пример Indy и посмотри там.
Папка по моему называеться DNSResolver
