Every .dk domain whose website address (A record) is announced by AS40509, 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 AS40509, counted once a day.
AS40509 is announced by Fly.io, Inc. (United States) and currently hosts 177 .dk domains in our dataset — 0.01% of all scanned .dk domains. Across all our scans we have observed 99 unique IPv4 addresses on this network, and the domains currently sit in 10 IPv4 CIDR blocks covering roughly 43.5 thousand addresses of IPv4 space.
IPv6 is live here too: 135 domains (76.3%) publish AAAA records from this AS, resolving to 89 unique IPv6 addresses across 1 prefix (about 65.5 thousand /64 networks of space).
We have not observed any nameservers or mail exchangers for .dk domains on this AS — the domains hosted here run their DNS and mail from other networks.
On the security side, 120 of the domains hosted here (67.8%) 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.
