📝 Original message:I'm bringing this issue up again. The current Bitcoin DNS seed
infrastructure is unstable. I assume this is because of we're using a
custom DNS implementation which is not 100% compatible. There have been
bugs in the past, like a case sensitive match for the domain name.
Current state (seeds taken from bitcoinj):
mainnet:
seed.bitcoin.sipa.be OK
dnsseed.bluematt.me OK
dnsseed.bitcoin.dashjr.org SERVFAIL, tried multiple ISPs
seed.bitcoinstats.com OK
testnet:
testnet-seed.bitcoin.petertodd.org SERVFAIL, just from Telefonica
testnet-seed.bluematt.me OK (but only returns one node)
Note: Telefonica is one of Europe's largest ISPs.
I would try to improve DNS myself, but I'm not capable of writing C. My
"fix" would be to reimplement everything in Java -- I doubt you guys
would be happy with that.
