The main difference between a static IP is that one is automatically assigned and could change at any time without any type of notice, and the other is requested by a customer, assigned by one of our tech support personnel and is then hard coded into your own equipment. The static IP we assign you will stay the same as long as possible. We only change them if we have to upgrade our network and it requires IP changes. We notify static IP customers if and when they would ever need to change.
