Yeah, I have a linksys router, WRT54G running DD-WRT v23 SP2  
(09/15/06) vpn which directly supports (among others) DynDNS.org.

So far it hasn't needed to update its IP address because in just over  
one month Comcast still is assigning the same IP address to the  
router. But DD-WRT is logging events for updating, indicating it  
knows its IP address is the same and doesn't need to send an update  
to DynDNS.org.

I suppose I could change the MAC address on the WAN port of the  
router and then reboot router and modem to get a new IP address, and  
see how long it takes for DynDNS to update. I'd guess few hours to a  
day...
