We got 4 ips on our server, and I noticed that one of our IP's appears to be blocked by a big whois providor.
Is there a way I can route whois lookups over a different IP - not just eth0?

No mention of OS, so the Windows equivalent is: `route add
mask 255.255.255.255 – Mark Henderson Apr 17 '10 at 01:47` -
If there's not multiple gateways or a router handling source NATs, would specifying the alias interface be enough? – Warner Apr 17 '10 at 01:49

Well, the question did mention eth0, so I took a stab – Matt Simmons Apr 17 '10 at 01:49

Sorry, didn't answer your question. If the remote server is blocking some (but not all) of your IPs, you can use route to prefer the interface with the unblocked IP. – Matt Simmons Apr 17 '10 at 02:02

Thanks - it's a Debian box. route add sounds like it could be the plan! I will look into this some more. – Wizzard Apr 17 '10 at 02:18

You'll need to alter your DNS settings to another IP address you own and alter your web server configurations to reflect the changes.

2He's asking how to change the source IP when routing out of the system with a client. – Warner Apr 17 '10 at 01:36

Damnit, I wasn't sure if he was asking that or what. I was going to post the route answer as well, but I read into that DNS was the issue. – David Rickman Apr 17 '10 at 03:31
