📄 Description

Hello,

this change adds support of specifying multiple explicitly configured listening IP addresses. This was previously not possible - either the service was listening on any (0.0.0.0/::) or on one address picked up by the operator (which may not be enough in dual-stacked environments).

This is useful in environments where you have multiple DNS servers listening on 53 (udp or tcp) and you want to distinguish between them by IPs. One DNS server may be listening on 127.0.0.1:53, [::1]:53, and another one on public IPs, e.g. 192.0.2.1:53,[2001:db8::1]:53.

Likely resolves #135
