It depends on the ISP. Over 25 years of IT support I've had to fight with about 30% of them to bring in my own device.
Most notable screwery was with Verizon DSL. They'd lease a new public IP every time we tried an incoming connection. As fast as I could record the new IP in the remote config and reconnect - my IP would change. I was able to push it past six changes/min.
