Selecting which IP address to use in Perl

Say I have a server with 4 ip addresses allocated to it:
example 12.34.56.1, 12.34.56.2, 12.34.56.3, 12.34.56.4
Whenever I connect to another server FROM my server it uses 12.34.56.1
Is there any way to write a script where I can either 'choose' which IP address to use to connect to other servers or cycle through them or even pick one of them randomly to use?

Assuming that you only have one NIC, you will only get traffic coming from the first address that is bound to it. If you have multiple NICs then the IP will be routed least cost, hence still tend to come from the same adapter. This should be true of any OS.

If you wanted to script something then you *may* be able to fool around with routing tables, however IMHO you are best to leave that alone, yoou could quickly end up with something that doesn't work at all !

I wondered if it was possible at all. The reason I want to do this is I want to use the whois statement but I need to check about 20,000 domains (for registration status) and I didn't want to run the risk of having an IP banned - was going to cycle through them.
Ah well if it's not possible it's not. I'll give it a couple of days to see if anyone can shed any light before I award the points.
