Every .dk domain whose website address (A record) is announced by AS203953, 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 AS203953, counted once a day.
AS203953 is announced by Hiper A/S (Denmark) and currently hosts 1,841 .dk domains in our dataset — 0.14% of all scanned .dk domains. Across all our scans we have observed 1,037 unique IPv4 addresses on this network, and the domains currently sit in 13 IPv4 CIDR blocks covering roughly 214 thousand addresses of IPv4 space.
IPv6 is live here too: 121 domains (6.6%) publish AAAA records from this AS, resolving to 60 unique IPv6 addresses across 1 prefix (about 34.4 billion /64 networks of space).
The network is part of the .dk zone's infrastructure too: 19 distinct nameservers and 425 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.
On the security side, 1,438 of the domains hosted here (78.1%) 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.
Hiper A/S announces 14 prefixes (13 IPv4, 1 IPv6) and reaches the internet through 1 upstream network.
