AS40509 is announced by Fly.io, Inc. (United States) and currently hosts 159 .dk domains in our dataset — 0.01% of all scanned .dk domains. Across all our scans we have observed 86 unique IPv4 addresses on this network, and the domains currently sit in 9 IPv4 CIDR blocks covering roughly 41.5 thousand addresses of IPv4 space.

IPv6 is live here too: 115 domains (72.3%) publish AAAA records from this AS, resolving to 73 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, 100 of the domains hosted here (62.9%) validate as DNSSEC-secure — right around the zone-wide average of 62.7%. See how this AS compares on the ASN statistics page, or drill into the CIDR list below the results.
