Your ISP CAN do this.  They just won't because they don't want to make it
easy for you to run a server.   They want to suppress your use.  You
might check with other ISPs or twist their arm more, or get a little
more sophisticated by letting DHCP set the IPs and have your domain
registered through one of the nameserver services that will allow you to 
reset the info each time you boot.   Then, there are some utilities you 
can get to check what IP got set and then notify that nameserver service.

I don't remember offhand the names of any of those services or the 
utilities you can use to talk to them, but there are several and you
can just do a little searching for them.
