I'm now on my second ISP where I find that using OpenDNS rather than the ISP's own DNS servers provides significantly faster responses to DNS queries at peak times, so it's becoming my DNS provider of choice.

My current ISP will only provide dynamic IP addresses and OpenDNS have client-side apps to update your own gateway IP address with them to keep your logs accurate and up-to-date, but it would be great if the 2820 could have this added as one of its DDNS providers so it can be handled direct from the router.

I think it would be a genuinely useful and very simple add-on.

Better would be their sister site DNS-O-Matic .

That too!

This would be very useful when using 3g mobile failover.
Please??

I second this request, and also ask for namecheap.com support, as they allow domains hosted with them to update dynamic hosts.
Currently you can use open source tomato firmware to keep your hosts pointing to your dynamic IP addresses.
Also many of the DDNS providers listed in DrayTek products are no longer free, notably DynDns.
If you don't want to work and support third parties, then setup your own free DDNS service for DrayTek products, say xxxhostxxx.mydraytek.com

Come on DrayTek get with the times please.
