SKY Wan IP address Dynamic or sticky?

Quick question people. I'm thinking of moving to Sky BB but would like a fairly fixed IP address. I know that they supply dynamic and can't do fixed but would it be at all 'sticky'? I've been with Pipex for 5 years on a non fixed service and had the same IP the whole time.

Thanks

No it changes when you reboot teh router

Mine changes everytime I resync the router to the exchange.

Thanks for the replies.

This being the case, is it true that DynDns works with the supplied router?

yeah, seems to work for me as I'm hosting a web site using DynDNS

Thanks for the replies guys. My concerns have now been addressed.
