🔄 Reverse NS Lookup

Find all domains using this nameserver

This page lists every .dk domain whose delegation includes the nameserver dns01.novi.dk, together with its IP addresses, network, zone-transfer and ANY-query behaviour, the protocols and RFCs it supports (TCP, EDNS, cookies, NSID, DNS over TLS/HTTPS …), the nameserver sets it is used in and how fast those sets answer. Use it to size a DNS provider, audit a migration or find domains still pointing at an old server. Data comes from our own scanners, which re-resolve every .dk domain in the zone roughly once a week.

Times are the scanner's own lookups through its resolver on each domain's latest scan, so they include resolver overhead; compare sets with each other rather than reading them as raw authoritative round-trip times.
