AS31477 is announced by Duocast B.V. (The Netherlands) and currently hosts 45 .dk domains in our dataset — <0.01% of all scanned .dk domains. Across all our scans we have observed 39 unique IPv4 addresses on this network, and the domains currently sit in 6 IPv4 CIDR blocks covering roughly 16.4 thousand addresses of IPv4 space.

IPv6 is live here too: 14 domains (31.1%) publish AAAA records from this AS, resolving to 12 unique IPv6 addresses across 2 prefixes (about 36.5 billion /64 networks of space).

The network is part of the .dk zone's infrastructure too: 11 distinct nameservers and 32 distinct mail exchangers serving .dk domains currently resolve to addresses announced by this AS.

On the security side, 11 of the domains hosted here (24.4%) 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.
