AS29056 Citycom Telekommunikation GmbHASN lookup: IP ranges, prefixes and network type

AS29056 is the autonomous system number (ASN) announced by Citycom Telekommunikation GmbH. It announces 17 prefixes, 33,024 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.

Directory data is unavailable at the moment, so the prefix list and the range membership counts are missing from this page. What you can see comes from the committed snapshot and is accurate as far as it goes. Try again shortly.

What AS29056 means for detection

Addresses on Citycom Telekommunikation GmbH are consumer connections: households and small businesses on a fixed line. Our engine classifies them residential, which is the class most likely to be a real customer, and the class fraud tools are least likely to flag. The catch is the residential proxy. An address here can be rented out by whoever holds the connection, and when that happens the ownership data on this page still reads as clean. That is a behavioural signal, not an ownership one.

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.
