Every .dk domain whose website address (A record) is announced by AS47292, 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 AS47292, counted once a day.
AS47292 is announced by Sentia Denmark A/S (Denmark) and currently hosts 20,607 .dk domains in our dataset — 1.57% of all scanned .dk domains. Across all our scans we have observed 1,365 unique IPv4 addresses on this network, and the domains currently sit in 79 IPv4 CIDR blocks covering roughly 103.9 thousand addresses of IPv4 space.
IPv6 is live here too: 203 domains (1.0%) publish AAAA records from this AS, resolving to 26 unique IPv6 addresses across 4 prefixes (about 17.2 billion /64 networks of space).
The network is part of the .dk zone's infrastructure too: 69 distinct nameservers and 808 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.
On the security side, 4,577 of the domains hosted here (22.2%) 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.
Sentia Denmark A/S announces 120 prefixes (114 IPv4, 6 IPv6) and reaches the internet through 4 upstream networks.
