Find all domains hosted on this ASN

Every .dk domain whose website address (A record) is announced by AS50664, 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.

Re:Sources France SAS

AS50664 is announced by Re:Sources France SAS (France) and currently hosts 18 .dk domains in our dataset — <0.01% of all scanned .dk domains. Across all our scans we have observed 1 unique IPv4 address on this network, and the domains currently sit in 1 IPv4 CIDR block covering roughly 4.1 thousand addresses of IPv4 space.

IPv6 is live here too: 2 domains (11.1%) publish AAAA records from this AS, resolving to 0 unique IPv6 addresses across 0 prefixes.

The network is part of the .dk zone's infrastructure too: 1 distinct nameserver and no mail exchangers serving .dk domains currently resolve to addresses announced by this AS.

On the security side, 0 of the domains hosted here (0.0%) 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.
