Across all our scans we have observed 9 unique IPv4 addresses on this network, and the domains currently sit in 4 IPv4 CIDR blocks covering roughly 18.4 thousand addresses of IPv4 space.

IPv6 is live here too: 1 domain (12.5%) publish AAAA records from this AS, resolving to 1 unique IPv6 address across 1 prefix (about 2.1 billion /64 networks of space).

The network is part of the .dk zone's infrastructure too: 9 distinct nameservers and 1 distinct mail exchanger serving .dk domains currently resolve to addresses announced by this AS.

On the security side, 3 of the domains hosted here (37.5%) validate as DNSSEC-secure — below the zone-wide average of 62.8%. See how this AS compares on the ASN statistics page, or drill into the CIDR list below the results.
