Look up DNS
What nine regions' resolvers answer, with the regions that agree grouped.
How it works
Each region asks its own hosting provider's recursive resolver, the one its servers use, with no cache of
its own in between, so a TTL is what that resolver has left. Regions that got the same records are grouped, TTLs aside;
different groups usually mean geo-DNS or a change still propagating. Records are only shown, never connected to.
An IP address looks up its PTR. The Mail type is MX, SPF and DMARC at once, showing only the SPF and DMARC
records among the TXT ones. From a terminal: curl ipq.sh/dns/example.com?type=MX or
curl ipq.sh/dns/example.com?mail.
