Seeder does not listen on ipv4 address, it works on ipv6 only.

Can you give us a bit more about your environment?
How do you start your seeder (arguments)?
Give us some logs?
Have you tried dig AAAA <yourseed> and did A <yourseed> from a remote host?

I've pulled in this PR #84 and it binds to an ipv4 but the protocol is upd6 in netstat, does that matter?

That shouldn't be a problem; you can bind an IPv6 socket to an IPv4 address. Does it work or not?

@cryptorex
Copy link

@sipa well, the seeder runs but its a new instance so I'm guessing it will take awhile to crawl for nodes and index them....

@cryptorex
Copy link

Just to follow up - I've let the seeder run using -a IPv4_ADDRESS_HERE and its working and responding to dig A requests with no issues.

It does still bind to the IPv6 socket, but as mentioned above, it does work.
