AS3303 is announced by Bluewin (Switzerland) and currently hosts 27 .dk domains in our dataset — <0.01% of all scanned .dk domains. Across all our scans we have observed 10 unique IPv4 addresses on this network, and the domains currently sit in 9 IPv4 CIDR blocks covering roughly 290.8 thousand addresses of IPv4 space.

IPv6 is live here too: 2 domains (7.4%) publish AAAA records from this AS, resolving to 2 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: 13 distinct nameservers and 9 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.

On the security side, 17 of the domains hosted here (63.0%) validate as DNSSEC-secure — right around 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.
