Every .dk domain whose website address (A record) is announced by AS204274, with the network's IPv6 and DNSSEC adoption and its observed prefixes. An autonomous system is the routing identity of a hosting company or ISP. Data comes from our own scanners, which re-resolve every .dk domain in the zone roughly once a week.
Active .dk domains whose website address (A record) is announced by AS204274, counted once a day.
AS204274 is announced by AURA Fiber A/S (Denmark) and currently hosts 702 .dk domains in our dataset — 0.05% of all scanned .dk domains. Across all our scans we have observed 433 unique IPv4 addresses on this network, and the domains currently sit in 3 IPv4 CIDR blocks covering roughly 65.5 thousand addresses of IPv4 space.
IPv6 is live here too: 1 domain (0.1%) publish AAAA records from this AS, resolving to 0 unique IPv6 addresses across 0 prefixes.
The network is part of the .dk zone's infrastructure too: 7 distinct nameservers and 155 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.
On the security side, 528 of the domains hosted here (75.2%) validate as DNSSEC-secure — well above the zone-wide average for domains with a web address, 70.5%. See how this AS compares on the ASN statistics page, or drill into the CIDR list below the results.
