AS25151 is announced by Cyso Group B.V. (The Netherlands) and currently hosts 84 .dk domains in our dataset — 0.01% of all scanned .dk domains. Across all our scans we have observed 23 unique IPv4 addresses on this network, and the domains currently sit in 9 IPv4 CIDR blocks covering roughly 12 thousand addresses of IPv4 space.

IPv6 is live here too: 48 domains (57.1%) publish AAAA records from this AS, resolving to 10 unique IPv6 addresses across 3 prefixes (about 38.7 billion /64 networks of space).

The network is part of the .dk zone's infrastructure too: 10 distinct nameservers and 10 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.

On the security side, 11 of the domains hosted here (13.1%) 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.
