Ask for an IP reservation to maintain the same address, if they won't do that, tell them to stop messing with the IP schemes as it keeps breaking your internet connection causing significant downtime and requires manual intervention every time. (unproductive work, lost hours of productivity, etc.)
I think firmware 1.9.0 will let you login to various DDNS providers and update the IP accordingly.
