AS56042 China Mobile communications corporationASN lookup: IP ranges, prefixes and network type

AS56042 is the autonomous system number (ASN) announced by China Mobile communications corporation. It announces 90 prefixes, 537,856 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 Mobile communications corporation announces, biggest first. These are a sample and not the full routing table: 90 prefixes do not fit on a page, and the ones worth showing are the ones most traffic comes from.

Look up an address on AS56042

What AS56042 means for detection

Addresses on China Mobile communications corporation are mobile: phones and tablets behind carrier NAT. Our engine classifies them residential, with one caveat worth knowing. Carrier NAT puts thousands of subscribers behind one address, so an IP-level block here reaches far more people than intended, and rate limits keyed on the address will punish an entire city. Geolocation is coarse for the same reason.

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.
