Every .dk domain whose website address (A record) is announced by AS39921, 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 AS39921, counted once a day.
AS39921 is announced by Rackspace Ltd. (Germany) and currently hosts 2 .dk domains in our dataset — <0.01% of all scanned .dk domains. Across all our scans we have observed 2 unique IPv4 addresses on this network, and the domains currently sit in 1 IPv4 CIDR block covering roughly 16.4 thousand addresses of IPv4 space.
We have yet to observe any IPv6 (AAAA) hosting on this AS.
The network is part of the .dk zone's infrastructure too: no nameservers and 1 distinct mail exchanger serving .dk domains currently resolve to addresses announced by this AS.
On the security side, 1 of the domains hosted here (50.0%) validate as DNSSEC-secure — below 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.
