how to detect multiple ip addresses

[sv]

is it possible to detect multiple IP addresses or Adapters in a computer? I want to list all the possible choices of the IPs available in a program. Anyone have examples or code or an overview of how its done?

I haven't done it myself, but you should be able to do something like (sorry, it's in C, but you ought to be able to see what's happening)

[tt]
DWORD cb = 0;
PROTOCOL_INFO *pPI;
BOOL pfLanas[100];
int nLanas = sizeof(pfLanas)/sizeof(BOOL);
int iRC;

// Determine output buffer size
iRC = EnumProtocols(NULL, NULL, &cb);

if (!cb)
return; // No adapters in system, or error

// Allocate a buffer
pPI = (PROTOCOL_INFO*) calloc(1, cb);

// Enumerate all protocols.
iRes = EnumProtocols( NULL, pPI, &cb );

// EnumProtocols() lists each lana number twice, once for
// SOCK_DGRAM and once for SOCK_SEQPACKET. Set a flag in
// pfLanas so unique lanas can be identified.

memset(pfLanas, 0, sizeof(pfLanas));

while (iRC > 0) {
// Scan protocols looking for AF_INET (TCP, IP).
if (pPI[--iRC].iAddressFamily == AF_INET)
// found one
pfLanas[abs(pPI[iRC].iProtocol)] = TRUE;
}
}

free(pPI);

Hope this helps.
