Every .dk domain whose website address (A record) is announced by AS4455, 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.
BSO IX Reach Ltd announces 61 prefixes (46 IPv4, 15 IPv6) and reaches the internet through 10 upstream networks.
Upstream and prefix data supplied by ipbot.dk; power is relative to the strongest upstream.
