The company I work for is a small ISP about to change providers. This means all their servers with external addresses will need to be changed. For unknown reasons, the people who originally set this up gave out lots of individual IP addresses to customers. This means that one server has potentially many IP addresses attached to one network card. Is there a way to have the Dude group IP addresses by physical address, so I can tell which IPs are on what server? The other problem here is that all these servers are running some variation of Linux. Thanks!
