Got this glorious error today. Both addresses are right, maybe there should be a way to run abra ipv4/ipv6 only?

FATA[0003] app domain collabora.ostrom.collective.tools (2a01:4f8:222:f0a::2) does not appear to resolve to app server ostrom.collective.tools (88.198.81.228)?

The workaround was to add the IPv4 address to /etc/hosts.: 88.198.81.228 collabora.ostrom.collective.tools

Sadness 😬 I guess abra should just grok whether it's reading a ipv4/ipv6 record and match accordingly? In this case, abra should have tried to look up the ipv6 record for ostrom.collective.tools to make the comparison, right?

➜ host ostrom.collective.tools
ostrom.collective.tools has address 88.198.81.228
ostrom.collective.tools has IPv6 address 2a01:4f8:222:f0a::2

So either would have worked, seems like the problem is that it did one kind of lookup on IPv4 and the other on IPv6.

Note, coop-cloud/abra#364 fixes that we do only stick to ipv4 when possible. I couldn't quite reproduce the issue but I think this could help fix it. This is ofc sadness for the ipv6 hackers amongst us. I welcome a change set which adapts this function to support ipv6 in the case of ipv4 matching failing. I think it's just repeating the logic and then passing "ip6" into the resolver.
