AS16509 is announced by Amazon.com, Inc. (United States) and currently hosts 40,203 .dk domains in our dataset — 3.02% of all scanned .dk domains. Across all our scans we have observed 9,312 unique IPv4 addresses on this network, and the domains currently sit in 204 IPv4 CIDR blocks covering roughly 50.5 million addresses of IPv4 space.
IPv6 is live here too: 2,554 domains (6.4%) publish AAAA records from this AS, resolving to 13,562 unique IPv6 addresses across 12 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 3,227 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.
On the security side, 12,966 of the domains hosted here (32.3%) validate as DNSSEC-secure — below 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.
