Across all our scans we have observed 142 unique IPv4 addresses on this network, and the domains currently sit in 7 IPv4 CIDR blocks covering roughly 3.6 thousand addresses of IPv4 space.

IPv6 is live here too: 751 domains (6.6%) publish AAAA records from this AS, resolving to 13 unique IPv6 addresses across 2 prefixes (about 131.1 thousand /64 networks of space).

The network is part of the .dk zone's infrastructure too: 28 distinct nameservers and 4,456 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.

On the security side, 6,848 of the domains hosted here (60.6%) validate as DNSSEC-secure — below the zone-wide average of 62.5%. See how this AS compares on the ASN statistics page, or drill into the CIDR list below the results.
