Yes there are.
API functions gethostbyname si gethostbyaddr are all you need. Take care with the includes, these are functions from WSOCK.DLL.

Hope this help,s-)

This will print the IP address of all the NICs in a PC.


struct in_addr addr;
struct hostent *phe;
char ac[80];
int i;
char *local;

// get the name of the local host
if (gethostname(ac, sizeof(ac)) == SOCKET_ERROR) {
printf("Error getting local host name: %d\n",WSAGetLastError());
return 1;
}
printf("Host name is %s\n",ac);
phe = gethostbyname(ac);
if (phe == 0) {
cerr << &quot;Error: Bad host lookup.&quot; << endl;
return 1;
}
for (i=0; phe->h_addr_list !=0; ++i) {
memcpy(&addr, phe->h_addr_list,sizeof(struct in_addr));
printf(&quot;Card %i) %s\n&quot;,i,inet_ntoa(addr));
local=inet_ntoa(addr);
}
