Every .dk domain whose website address (A record) is announced by AS16509, 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 AS16509, counted once a day.
AS16509 is announced by Amazon.com, Inc. (United States) and currently hosts 41,830 .dk domains in our dataset — 3.20% of all scanned .dk domains. Across all our scans we have observed 11,878 unique IPv4 addresses on this network, and the domains currently sit in 203 IPv4 CIDR blocks covering roughly 48.5 million addresses of IPv4 space.
IPv6 is live here too: 2,714 domains (6.5%) publish AAAA records from this AS, resolving to 22,894 unique IPv6 addresses across 10 prefixes (about 1.1 trillion /64 networks of space).
The network is part of the .dk zone's infrastructure too: 2,920 distinct nameservers and 3,741 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.
On the security side, 14,234 of the domains hosted here (34.0%) 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.
