Every .dk domain whose website address (A record) is announced by AS23005, 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 AS23005, counted once a day.
AS23005 is announced by SWITCH, LTD (United States) and currently hosts 13 .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 2 IPv4 CIDR blocks covering roughly 5.1 thousand addresses of IPv4 space.
We have yet to observe any IPv6 (AAAA) hosting on this AS.
We have not observed any nameservers or mail exchangers for .dk domains on this AS — the domains hosted here run their DNS and mail from other networks.
On the security side, 1 of the domains hosted here (7.7%) 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.
SWITCH, LTD announces 174 prefixes (161 IPv4, 13 IPv6) and reaches the internet through 5 upstream networks.
