Every .dk domain whose website address (A record) is announced by AS20738, 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 AS20738, counted once a day.
AS20738 is announced by Heart Internet limited (United Kingdom) and currently hosts 78 .dk domains in our dataset — 0.01% of all scanned .dk domains. Across all our scans we have observed 49 unique IPv4 addresses on this network, and the domains currently sit in 6 IPv4 CIDR blocks covering roughly 13.1 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: 6 distinct nameservers and 66 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.
On the security side, 9 of the domains hosted here (11.5%) 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.
