Every result on this page comes from our own scans of the .dk zone — not a third-party feed. The scanner continuously walks the zone and geolocates every address it finds; so far that adds up to 1,330,304 of the 1,330,552 registered .dk domains resolved and mapped, built from 11,534,649 scans and counting.

On the network side we have observed 111,503 unique IPv4 addresses inside 7,834 CIDR blocks — together spanning roughly 341 million addresses of IPv4 space — announced by 2,523 distinct autonomous systems from 2,302 providers across 86 countries. IPv6 adds another 170,597 unique addresses in 714 prefixes (about 7.7 trillion /64 networks of space), published by 224,372 domains (16.9% of the scanned zone).

Security-wise, 836,007 domains (62.8%) currently validate as DNSSEC-secure, while 24,780 fail validation outright (bogus). The full breakdown lives on the zone statistics page.

Beyond raw addresses, the dataset tracks 20,439 distinct nameservers and 216,871 mail hosts, plus TXT/SPF, CAA, TLSA/DANE, MTA-STS, SOA and PTR details for every domain — all cross-referenced, so a single ASN, CIDR or nameserver unfolds into its full hosting footprint through the reverse-lookup tools.
