The only time you would normally get a delay is if the BBS is not listening on
IPv6, but has an AAAA record.  Then IPv6 capable hosts will experience a delay
as they try a non existent IPv6 service, before falling back to IPv4.

IPv4 hosts aren't affected.  They'll simply look up the A record and make an
IPv4 connection straight away.

Shouldn't have any issues, provided you're listening on both IPv4 and IPv6.
