So generally it seems impossible to have both DNS seeds running on same IP
address. Too bad.
Ok, I'll switch to serving only testnet DNS on this server for now, as this
seems to be a much bigger problem than mainnet. Later I might buy second IP
to setup mainnet DNS also.
Best regards,
Alex

Hi Peter
I've setup DNS seeds myself a week ago, at testnet-seed.alexykot.me and
bitcoin-seed.alexykot.me, but there is a problem with DNS settings that we
with Andreas couldn't sort out quickly.
The problem itself is that I can reach my nameserver and get dnsseed
response if I query it directly
Hi Alex,
I think the problem is with my suggestion to use bind forwarding..
basically bind is stripping off the authorative answer bit in the
reply.. this causes the recursor to go into a loop chasing the authority
server which again returns a non-authoritve answer with itself as the
No, I don't think so. The problem is the 'aa' flag is missing (see the
'flags' section in dig). Perhaps if you could suppress the authority
records the recursor would give up and just accept the non-authorative
answer, but that isn't a good solution even if it might work for some
resolvers.
A simple hack would be to crontab up a couple of dig scripts that every
minute 'dig' (dig's output is in bind zonefile format) the bitcoin-seed
and write the results to two zonefiles that bind can then serve.
Basically
dig @127.0.0.1 -p 5353 zonefile1.zone
dig @127.0.0.1 -p 5354

You're very quick to point at others. Especially since they run software
that had the time to mature for about 30 years, and the protocol didn't
really change since then...
The last time it didn't work, the bug -- non RFC-conformance -- was on
the bitcoin seeders side. ISPs do weird things with

FWIW
That said, keep in mind the github discussion(1) that was had: if all
the DNS seeds being down breaks your application, your application is
broken and insecure. The only exception is initial startup, and even
then you should have fallbacks such as hardcoded node lists and manual
peer entry.
