🌐 Reverse ASN Lookup

Find all domains hosted on this ASN

Every .dk domain whose website address (A record) is announced by AS224, 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.
