Find all domains hosted on this ASN

Every .dk domain whose website address (A record) is announced by AS4808, 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.

China Unicom Beijing Province Network

AS4808 is announced by China Unicom Beijing Province Network (China) and currently hosts 2 .dk domains 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 262.1 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 no mail exchangers serving .dk domains currently resolve to addresses announced by this AS.

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.
