AS2856 is announced by British Telecommunications PLC (United Kingdom) and currently hosts 15 .dk domains in our dataset — <0.01% of all scanned .dk domains. Across all our scans we have observed 10 unique IPv4 addresses on this network, and the domains currently sit in 6 IPv4 CIDR blocks covering roughly 6.8 million addresses of IPv4 space.
We have yet to observe any IPv6 (AAAA) hosting on this AS.
The network is part of the .dk zone's infrastructure too: 11 distinct nameservers and 9 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.
On the security side, 5 of the domains hosted here (33.3%) validate as DNSSEC-secure — below the zone-wide average of 62.8%. See how this AS compares on the ASN statistics page, or drill into the CIDR list below the results.
