Every .dk domain whose website address (A record) is announced by AS20473, 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 AS20473, counted once a day.
AS20473 is announced by The Constant Company, LLC (The Netherlands) and currently hosts 1,131 .dk domains in our dataset — 0.09% of all scanned .dk domains. Across all our scans we have observed 658 unique IPv4 addresses on this network, and the domains currently sit in 48 IPv4 CIDR blocks covering roughly 741.1 thousand addresses of IPv4 space.
IPv6 is live here too: 168 domains (14.9%) publish AAAA records from this AS, resolving to 139 unique IPv6 addresses across 6 prefixes (about 1.1 billion /64 networks of space).
The network is part of the .dk zone's infrastructure too: 116 distinct nameservers and 289 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.
On the security side, 473 of the domains hosted here (41.8%) 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.
