DNS lookup

Everything DNS says about a domain: traced from the root servers down, every record type asked of the domain's own nameservers, each nameserver checked, then every hostname and policy record it points at followed, with SPF, DMARC, DKIM and DNSSEC checked along the way.

Warning The parent zone delegates to dns1.p01.nsone.net, dns2.p01.nsone.net, dns3.p01.nsone.net, dns4.p01.nsone.net but 46.54.45.in-addr.arpa itself lists dns1.p06.nsone.net, dns2.p06.nsone.net, dns3.p06.nsone.net, dns4.p06.nsone.net, ns01.dnsfaster.com, ns02.dnsfaster.com, ns03.dnsfaster.com, ns04.dnsfaster.com. Make the two lists match.
Note 46.54.45.in-addr.arpa isn't signed with DNSSEC, so resolvers can't tell forged answers from real ones.

Highlighted values differ from the authoritative answer: either a recent change they haven't picked up yet (the TTL says how long until they do), or, for A and AAAA, a CDN or geo-routed site handing each resolver location its own addresses.
