AS1257 is announced by Tele2 SWIPnet (Sweden) and currently hosts 3,097 .dk domains in our dataset — 0.23% of all scanned .dk domains. Across all our scans we have observed 88 unique IPv4 addresses on this network, and the domains currently sit in 24 IPv4 CIDR blocks covering roughly 2.5 million addresses of IPv4 space.
IPv6 is live here too: 5 domains (0.2%) publish AAAA records from this AS, resolving to 9 unique IPv6 addresses across 3 prefixes (about 274.9 billion /64 networks of space).
The network is part of the .dk zone's infrastructure too: 45 distinct nameservers and 51 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.
On the security side, 120 of the domains hosted here (3.9%) validate as DNSSEC-secure — below the zone-wide average of 62.6%. See how this AS compares on the ASN statistics page, or drill into the CIDR list below the results.
