🌐 Reverse ASN Lookup

AS20559 is announced by Fundaments B.V. (The Netherlands) and currently hosts 35 .dk domains in our dataset — <0.01% of all scanned .dk domains. Across all our scans we have observed 17 unique IPv4 addresses on this network, and the domains currently sit in 6 IPv4 CIDR blocks covering roughly 12.3 thousand addresses of IPv4 space.

IPv6 is live here too: 29 domains (82.9%) publish AAAA records from this AS, resolving to 9 unique IPv6 addresses across 2 prefixes (about 8.6 billion /64 networks of space).

The network is part of the .dk zone's infrastructure too: 8 distinct nameservers and 5 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.

On the security side, 1 of the domains hosted here (2.9%) 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.

Fundaments B.V. announces 38 prefixes (31 IPv4, 7 IPv6) and reaches the internet through 10 upstream networks.
