DNS seeds for Namecore

Currently, Namecore (reimplementation of Namecoin on top of the modern Bitcoin Core code) does not have a suitable method of discovering peers. IRC discovery is not present since it was removed from Bitcoin long ago; instead, Bitcoin uses a combination of hardcoded nodes and DNS seeds. I think we should enable those for Namecoin as the next deployment step of Namecore. Is anyone interested and willing to either run stable and high-capacity nodes that could be hardcoded into the client as fallbacks, or to run a DNS seed?

I can run a DNS seed.

I can run a DNS seed and a high availability/capacity node.

I have a working fork of bitcoin-seeder:

You will need to edit the hardcoded IP address here in order to get it started:

I can publish the same set under different names, which might be a good idea.
Also I noticed the crawler didn't pick up any IPv6 nodes - do I have to enable that somehow, or are there no active IPv6 nodes?

Wow, thanks for the quick reaction! Great to see so much help in the community!
I'll wait a bit longer for Ryan's node and seed (?), and will then add those for now to the code.
BTW, is anyone also running a testnet seed? Not important, but could be useful nevertheless.

Added the quisquis.de DNS seed. It seems to work, Namecore can successfully discover peers with that. When Tor is used as proxy, it does not work, though. But this may be something that also doesn't work with Bitcoin (not sure). They have hardcoded .onion nodes, too.

I've never used Tor. I suppose it tunnels DNS queries, too? Can you check if this is a DNS problem, or a connection problem?
