Every .dk domain whose website address (A record) is announced by AS1257, 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 AS1257, counted once a day.
AS1257 is announced by Tele2 SWIPnet (Sweden) and currently hosts 3,101 .dk domains in our dataset — 0.24% of all scanned .dk domains. Across all our scans we have observed 95 unique IPv4 addresses on this network, and the domains currently sit in 25 IPv4 CIDR blocks covering roughly 2.8 million addresses of IPv4 space.
IPv6 is live here too: 4 domains (0.1%) publish AAAA records from this AS, resolving to 10 unique IPv6 addresses across 4 prefixes (about 274.9 billion /64 networks of space).
The network is part of the .dk zone's infrastructure too: 43 distinct nameservers and 60 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.
On the security side, 114 of the domains hosted here (3.7%) 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.
SWIPNET - Tele2 Sverige AB announces 423 prefixes (386 IPv4, 37 IPv6) and reaches the internet through 10 upstream networks.
Upstream and prefix data supplied by ipbot.dk; power is relative to the strongest upstream.
