AS23122 DSUASN lookup: IP ranges, prefixes and network type

AS23122 is the autonomous system number (ASN) announced by DSU. It announces 1 prefixes, 65,536 IPv4 addresses in total. Every address inside those ranges is routed by this operator, which is what makes the number the shortest answer to who runs a given address.

The last two rows are a second opinion, counted against the X4BNet VPN and datacenter range lists rather than read off the operator name. A network with most of its prefixes in the VPN list is carrying anonymised traffic whatever it calls itself.

Sample prefixes

The largest ranges DSU announces, biggest first. These are a sample and not the full routing table: 1 prefixes do not fit on a page, and the ones worth showing are the ones most traffic comes from.

Look up an address on AS23122

The field is prefilled with 138.247.0.1, the first address of the largest range above. Change it for one from your own logs and you get the network, the operator and the verdict for that specific address.

What AS23122 means for detection

Registry data does not say what kind of network DSU runs, and this page will not guess. Ownership alone cannot settle it: the name is the only clue an ASN carries about purpose, and this one carries none. A single address on it can still be classified, because that uses behaviour and range membership rather than the operator's name. Run one below and see what comes back.

The verdict for a single address is never settled by the ASN alone. It is the starting point, and IP Detection adds range membership, behaviour and history on top of it before it answers.
