AS24971 is announced by MasterDC s.r.o. (Czechia) and currently hosts 20 .dk domains in our dataset — <0.01% of all scanned .dk domains. Across all our scans we have observed 18 unique IPv4 addresses on this network, and the domains currently sit in 9 IPv4 CIDR blocks covering roughly 32.8 thousand addresses of IPv4 space.

IPv6 is live here too: 1 domain (5.0%) publish AAAA records from this AS, resolving to 2 unique IPv6 addresses across 1 prefix (about 33.6 million /64 networks of space).

The network is part of the .dk zone's infrastructure too: 12 distinct nameservers and 16 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.

On the security side, 6 of the domains hosted here (30.0%) 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.
