I've been using duiadns for about six months and i'm really pleased. You are doing a great job with IPv6 and that's what makes your service so special!
A dynamic dns service as good as many others with a plus on v6!
A very pleasant surprise for me. I've been looking for quite some time something similar for my IPv6 devices.
I'm using duiadns on my open-wrt router. I have only IPv4 since my ISP didn't offer IPv6 yet.
I'm using duiadns for "ipv6 for lan" feature. It is a very interesting approach, congrats!
I'm using your client on my pc because duiadns is not supported on my original cpe's firmware (linksys wrt54-gl).
It's free and is working fine. I like it!
I recently moved to duiadns since i was searching for a free dynamic dns with ipv6 support. I think i'll stay.
A good service, thought it wasn't so simple for me to make it work.
I'm using duiadns as a managed DNS provider with my own domain. Good value for money.
