IP Addresses

[Ruxpin]

If I have 2 network card and a modem in a pc. How can I find out what IP address is bound to each device?

You look inside your brain, and try to remember what IP you assigned both cards (which is done from the software).

If you run windows, right-click on Network, the Properties, then choose tcp/ip and check properties for that oto.

This being a VB forum, I was hoping to find a way to do this through code. But thank you for your intelligent reply.

Well, you can't!

Unless you write your own network driver that is (which can't be done in vb) of course. Winsock will only connect to specified ports.

If you learn how to use Api to send messages trough the windows network drivers, you might be able to send a out a BroadCast (or possibly a MultiCast) to the network in hope that all other network devices respond. Of course, you'll only end up with their Mac-adress which you'd have to connect to manually (which isn't easy) and ask for the ip.

Or you could let your program ping with a winsock all possible ip's (that's 4228250625 of them) until all have answered and then you know.

Thanks Dim. That works, but it only returns me one of the ip addresses assigned to the machine.

run the dos command

on NT

IPCONFIG

or on Win9x

i think its winipcfg

Try the ActiveX control from http://www.Catalyst.com called
SOCKETWRENCH
It provides properties such as .AdaptorAddress(Index) and
.AdaptorCount
This allows you to not only find out the IP address for each network adaptor (including dial-up) but you can then BIND the control to that network adaptor to enable network comms similar to other socket controls.
