AS20857 is announced by Signet B.V. (The Netherlands) and currently hosts 559 .dk domains in our dataset — 0.04% of all scanned .dk domains. Across all our scans we have observed 245 unique IPv4 addresses on this network, and the domains currently sit in 27 IPv4 CIDR blocks covering roughly 158.2 thousand addresses of IPv4 space.

IPv6 is live here too: 131 domains (23.4%) publish AAAA records from this AS, resolving to 75 unique IPv6 addresses across 7 prefixes (about 12.9 billion /64 networks of space).

The network is part of the .dk zone's infrastructure too: 101 distinct nameservers and 217 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.

On the security side, 167 of the domains hosted here (29.9%) 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.
