AS4812 China Telecom (Group)ASN lookup: IP ranges, prefixes and network type

AS4812 is the autonomous system number (ASN) announced by China Telecom (Group). It announces 611 prefixes, 7,873,279 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 China Telecom (Group) announces, biggest first. These are a sample and not the full routing table: 611 prefixes do not fit on a page, and the ones worth showing are the ones most traffic comes from.

What AS4812 means for detection

Addresses on China Telecom (Group) 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.
