Every .dk domain whose website address (A record) is announced by AS58087, with the network's IPv6 and DNSSEC adoption and its observed prefixes. An autonomous system is the routing identity of a hosting company or ISP. Data comes from our own scanners, which re-resolve every .dk domain in the zone roughly once a week.
Active .dk domains whose website address (A record) is announced by AS58087, counted once a day.
AS58087 is announced by Florian Kolb (Germany) and currently hosts 46 .dk domains in our dataset — <0.01% of all scanned .dk domains. Across all our scans we have observed 29 unique IPv4 addresses on this network, and the domains currently sit in 13 IPv4 CIDR blocks covering roughly 4.9 thousand addresses of IPv4 space.
IPv6 is live here too: 10 domains (21.7%) publish AAAA records from this AS, resolving to 6 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: 2 distinct nameservers and 16 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.
On the security side, 27 of the domains hosted here (58.7%) validate as DNSSEC-secure — below the zone-wide average for domains with a web address, 70.5%. See how this AS compares on the ASN statistics page, or drill into the CIDR list below the results.
Florian Kolb announces 36 prefixes (31 IPv4, 5 IPv6) and reaches the internet through 1 upstream network.
