AS51013 is announced by WebSupport s.r.o. (Sweden) and currently hosts 309 .dk domains in our dataset — 0.02% of all scanned .dk domains. Across all our scans we have observed 49 unique IPv4 addresses on this network, and the domains currently sit in 5 IPv4 CIDR blocks covering roughly 6.1 thousand addresses of IPv4 space.

IPv6 is live here too: 192 domains (62.1%) publish AAAA records from this AS, resolving to 26 unique IPv6 addresses across 3 prefixes (about 8.6 billion /64 networks of space).

The network is part of the .dk zone's infrastructure too: 7 distinct nameservers and 113 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.

On the security side, 107 of the domains hosted here (34.6%) validate as DNSSEC-secure — below the zone-wide average of 62.7%. See how this AS compares on the ASN statistics page, or drill into the CIDR list below the results.
