It's called correcting a  mistrake[sic] in your spew ;)

DynDNS is a service and company at http://www.dyndns.org that allows 
you to set up non-static IP hosts with the DynDNS system so that when 
they get a different IP address they can trigger an update at DynDNS 
to change their

No, DD-WRT does DynDNS not DynamicDNS.

Which is, as pointed out, not Dynamic DNS.

DynamicDNS is where as you do things like assign IP addresses to 
machines using DHCP you also -- get this -- *dynamically* assign a 
DNS forward and reverse entry in your DNS service for the machine in 
question. It's an integral part of Active Directory and an RFC.

So it is not in any way shape or for the same thing.
That is DynDNS != Dynamic DNS.
