We currently have 5 dedicated ip's with an isp (dsl) and we are looking for a backup isp (which will be cable) with 5 dedicated ip's. The problem is that I'm assuming we wont be able to get the same ip addresses, and I don't want to have to reprogram all the things that use those ip addresses in the event that we need to switch.
This will be a backup for times when the dsl goes down,. and we need a quick easy way to switch while the dsl gets repaired. I have no idea what we need to do... I was thinking some sort of router which will translate. Ideas?
