AS38019 is the autonomous system number (ASN) announced by tianjin Mobile Communication Company Limited. It announces 109 prefixes, 241,408 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.
AS38019 at a glance
| Organisation | tianjin Mobile Communication Company Limited |
|---|---|
| Autonomous system | AS38019 |
| Network type | Mobile carrier |
| IPv4 prefixes | 88 |
| IPv6 prefixes | 21 |
| IPv4 addresses | 241,408Summed across every announced prefix. IPv6 is not counted; the numbers are meaningless at that scale. |
| In known VPN ranges | 0 of 88 prefixes |
| In known datacenter ranges | 0 of 88 prefixes |
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.

What AS38019 means for detection
Addresses on tianjin Mobile Communication Company Limited 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.
