For months my IP address has been the same. The suddenly my speeds went through the floor for about a week and my IP address changed. I now have an excellent connection and my IP address has gone back to as before. I have looked at the Speedtest logs and while my speed was slow I had a different IP address up to the very hour that everything reverted to normal. Why would this happen?
I'm referring to my Virgin Cable line (see below), not to be confused with BT whom I know change IP addresses frequently.
