A successful IPv4 check comes from 4.az2.co.uk, which has an A record.
A successful IPv6 check comes from 6.az2.co.uk, which has an AAAA record.
If both succeed, your browser has dual-stack reachability to these independent paths.
Country, city and ASN information comes from the local GeoLite2 databases and is an approximate network location, not a statement about a person or precise address. An RFC1918 IPv4 result can be expected when you are using this tool from inside the private network.
