This page lists every .dk domain whose delegation includes the nameserver ns4.reverse.deploy.akamaitechnologies.com, 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.
Not probed yet. This nameserver is queued; the probe runs in the background and the result usually shows here within a few minutes.

in-addr.arpa / ip6.arpa zones delegated to ns4.reverse.deploy.akamaitechnologies.com, found from the SOA of the reverse name of each IPv4 /24 behind the zone's websites (and any CIDR page viewed), so the zone is the real delegation point, at whatever prefix length it sits. A /24 whose reverse delegation is broken (SERVFAIL) is not credited to anyone.
