I have forked a copy of SIPA's bitcoin-seeder and it was initially working fine. I've just tested again today and can see that it's not responding at all. Further investigation shows that my two DNS seeders are listening on IPv6 only, however the servers don't have an IPv6 address at all.
Does anyone know how to make SIPA's bitcoin-seeder listen on IPv4 only?
My fork is at
https://github.com/CRDS/credits-seederI'm running the seeder using screen -dm -t "dnsseed" bash -c 'cd credits-seeder/; ./dnsseed -h dnsseed1.crds.co -n 8.8.8.8 -m my.email.address'
All assistance is greatly appreciated.
