Every .dk domain whose website address (A record) is announced by AS4373, 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 AS4373, counted once a day.
AS4373 is announced by Online Computer Library Center (United States) and currently hosts 1 .dk domain in our dataset — <0.01% of all scanned .dk domains. Across all our scans we have observed 1 unique IPv4 address on this network, and the domains currently sit in 1 IPv4 CIDR block covering roughly 65.5 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, 0 of the domains hosted here (0.0%) 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.
OCLC-AS - Online Computer Library Center announces 19 prefixes (19 IPv4, 0 IPv6) and reaches the internet through 7 upstream networks.
Upstream and prefix data supplied by ipbot.dk; power is relative to the strongest upstream.
