How can I conveniently find a list of ISP with dynamic IP?

I'm on Zen at the moment. The service has been good but they only provide static IP. Where can I find a list of ISP that comes with dynamic IP? Thanks

Go to the TBB main front page, go to ISP search on the left menu, go to advanced pacjage search at the top.

The tenth option on the list is "IP Assignment Method".

(Remember to assign the wholesale providers at the bottom correctly. Some people only get BT etc.)
