Every .dk domain whose website address (A record) is announced by AS54113, 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 AS54113, counted once a day.
AS54113 is announced by Fastly, Inc. (United States) and currently hosts 3,420 .dk domains in our dataset — 0.26% of all scanned .dk domains. Across all our scans we have observed 172 unique IPv4 addresses on this network, and the domains currently sit in 11 IPv4 CIDR blocks covering roughly 203.3 thousand addresses of IPv4 space.
IPv6 is live here too: 409 domains (12.0%) publish AAAA records from this AS, resolving to 80 unique IPv6 addresses across 6 prefixes (about 4.3 billion /64 networks of space).
The network is part of the .dk zone's infrastructure too: no nameservers and 59 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.
On the security side, 2,250 of the domains hosted here (65.8%) 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.
Fastly, Inc. announces 1,808 prefixes (605 IPv4, 1,203 IPv6) and reaches the internet through 10 upstream networks.
Upstream and prefix data supplied by ipbot.dk; power is relative to the strongest upstream.
