Most of us know how easy it is to setup a dynamic DNS address to account for a dynamic IP address from an ISP (for example, anything.dyndns.com is updated to a dynamic IP address via a software client or a router). It would be great if you could enter that Dynamic DNS address (again, for example, anything.dyndns.com) into OpenDNS' settings instead of an IP address. OpenDNS would then know what IP address you are coming at their DNS servers from by reolving that Dynamic DNS name.

Since my router is already updating my DynDNS Account automatically, so why should I install some software to do the same task a second time?
This would be great because many routers do not allow you to put in a custom Dynamic DNS service. The may only let you choose a service from a list. I solved this by installing a Dynamic DNS client on a PC in the network. This is not optimal because the IP will not be updated if that PC is turned off.
I am using the client currently, but the dyndns.org addition would be great.
All the PC's in my home are laptops. I worry that when I or my wife are at work it would update the IP address with the work IP. I have dyndns installed on my router. Reverse DNS on OpenDNS would be perfect.

This idea is a cure for many free dns users out there without the need to install/use *yet-another* interface to keep things running as they do before using this service.
FE:
My router only supports DynDns or TZO for DDNS-updates.
If i want to use DNS-O-Matic service then i would need to install *yet-another* software _AND_ disable my router's DDNS client....
I started a very small service to populate DynDNS (or any other free hostname provider) changes to DNS-O-Matic (and OpenDNS through that).
You would have to give your DNS-O-Matic Username and Password away, though.
You can give it a try here: http://dnsalloc.appspot.com/

I just had this same idea occur to me, but i wanted to check and make sure it hadn't already been posted.
until we start seeing routers with DDNS options built in for opendns (or, possibly better, dns-o-matic) we need somethings like this.
no software to install, no fuss, no hassle. just let opendns accept a fqd in the network settings and pull the ip from there.
Marc's dnsalloc.appspot.com posted above is also a potential fix, but it feels more like a workaround than a true solution. i'll probably use it until something better comes along. good job Marc.
Ahm? I'm not sure if I get the point...
The problem is, DynDNS is not updated when my connection is down? Well... I suppose the DNS-o-Matic doesn't even update the information when I shut down my PC. My Router is online about anytime and updating my IP as soon as it connects (i.e. whenever my connection has been terminated). Sounds a lot saver to me, than using that software. My DynDNS Account is correct nearly (and I only say nearly because there might be slight downtimes about 1s each day or something) all of the time, since my router is configured to be online anytime even if no PC is connected.
opendns have tightened up a 'loophole' in their update and now if you use dnsalloc to update from dyndns to opendns you get an error as it's coming from marc's ip not your own. it stopped working 26/27 june 09. it wasn't broke, so opendns 'fixed' it and now it is broke.
Unfortunately, this idea won't work as OpenDNS needs to go from the IP address (when receiving a DNS query) to figure out which account's settings apply. They can't go through all the accounts doing name->IP lookups on each request (or even every so often) to figure out the mapping from IP address to account. And for most dynamic IPs, the DNS reverse records will point at the ISP's namespace anyhow, so that's no help.
Your best bet is DNS-o-Matic, or configuring ddclient to update both DynDNS (or whatever your dynamic DNS provider is) and OpenDNS network records at the same time.
