This page lists every .dk domain whose delegation includes the nameserver ns1.upc.biz, together with its IP addresses, network, zone-transfer and ANY-query behaviour, 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 ns1.upc.biz appears in the delegation of 3 .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 64.0%, while 3 (100.0%) are unsigned, with none failing validation outright.
Delegation health looks clean, too: none of these domains currently register as lame delegations at this nameserver.
Response time: across 3 timed domains, our resolver needed 786 ms on average to answer an A query and 137 ms for an NS query. Per nameserver set below.
| Nameserver set | Domains | Avg response (A) | NS lookup |
|---|---|---|---|
| ns1.upc.biz · ns2.upc.biz | 3 | 786 ms | 137 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.
