AS54113 is announced by Fastly, Inc. (United States) and currently hosts 3,204 .dk domains in our dataset — 0.24% of all scanned .dk domains. Across all our scans we have observed 170 unique IPv4 addresses on this network, and the domains currently sit in 9 IPv4 CIDR blocks covering roughly 201.7 thousand addresses of IPv4 space.

IPv6 is live here too: 370 domains (11.5%) publish AAAA records from this AS, resolving to 80 unique IPv6 addresses across 7 prefixes (about 8.6 billion /64 networks of space).

The network is part of the .dk zone's infrastructure too: no nameservers and 53 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.

On the security side, 2,104 of the domains hosted here (65.7%) validate as DNSSEC-secure — well above the zone-wide average of 62.5%. See how this AS compares on the ASN statistics page, or drill into the CIDR list below the results.
