This page lists every .dk domain whose delegation includes the nameserver ns4.darkserv.net, 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.
The nameserver ns4.darkserv.net appears in the delegation of 13 .dk domains in our dataset — <0.01% of every scanned .dk domain. The full list is below — here is how those domains look under the hood.
On the DNSSEC side, 0 (0.0%) validate as secure — below the zone-wide average of 63.9%, while 12 (92.3%) are unsigned, with none failing validation outright — a further 1 come back indeterminate.
Delegation health looks clean, too: none of these domains currently register as lame delegations at this nameserver.
Response time: across 13 timed domains, our resolver needed 4,343 ms on average to answer an A query and 3,201 ms for an NS query. Per nameserver set below.
Not profiled: it has no public IPv4 address we could resolve. Retried every few days.
| Nameserver set | Domains | Avg response (A) | NS lookup |
|---|---|---|---|
| ns1.darkserv.net · ns2.darkserv.net · ns3.darkserv.net · ns4.darkserv.net | 13 | 4,343 ms | 3,201 ms |
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.
| Reverse zone | Prefix | Prefixes | Checked |
|---|---|---|---|
| 218.245.91.in-addr.arpa | 91.245.218.0/24 | 1 | 2026-10-18 |
in-addr.arpa / ip6.arpa zones delegated to ns4.darkserv.net, 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.
