Following in the tradition of Netflix, Dyndns ( http://www.dyndns.com/ made a significant price increase in their service this year.
Since most computers do NOT have a static (unchanging) IP address, Dyndns can be used to give a static front end web address to a computer even though the backend (the ip address) constantly changes.
The price started at $12/year. I paid that for a long time. Then went to $15 a couple of years ago. THIS year however, there was a 33% price hike. From $15/year to $20/year. If I didn't need it, I wouldn't use it, but it provides a seamless way to always reach my computer.
My router (running dd-wrt) detects an IP address change, and automatically updates dDndns so it always points to my computer.
Damned if you do, Damed if you don't."
