AS22927 at a glance
| Organisation | Telefonica de Argentina |
|---|---|
| Autonomous system | AS22927 |
| Network type | Consumer ISP |
| IPv4 prefixes | 205 |
| IPv6 prefixes | 9 |
| IPv4 addresses | 4,104,192Summed across every announced prefix. IPv6 is not counted; the numbers are meaningless at that scale. |
| In known VPN ranges | 0 of 205 prefixes |
| In known datacenter ranges | 0 of 205 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 AS22927 means for detection
Addresses on Telefonica de Argentina 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.
