AS54113 is announced by Fastly, Inc. (United States) and currently hosts 3,191 .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 10 IPv4 CIDR blocks covering roughly 234.5 thousand addresses of IPv4 space.

IPv6 is live here too: 367 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 52 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.

On the security side, 2,096 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.
