AS19527 GOOGLE-2ASN lookup: IP ranges, prefixes and network type
AS19527 is the autonomous system number (ASN) announced by GOOGLE-2. It announces 42 prefixes, 856,576 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.
AS19527 at a glance
| Organisation | GOOGLE-2 |
|---|---|
| Autonomous system | AS19527 |
| Network type | Hosting and cloud |
| IPv4 prefixes | 41 |
| IPv6 prefixes | 1 |
| IPv4 addresses | 856,576Summed across every announced prefix. IPv6 is not counted; the numbers are meaningless at that scale. |
| In known VPN ranges | 0 of 41 prefixes |
| In known datacenter ranges | 4 of 41 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.
Sample prefixes
The largest ranges GOOGLE-2 announces, biggest first. These are a sample and not the full routing table: 42 prefixes do not fit on a page, and the ones worth showing are the ones most traffic comes from.

What AS19527 means for detection
Addresses on GOOGLE-2 are infrastructure: servers, containers and managed services, not people at home. Our engine classifies them datacenter or hosting and never as VPN, because renting a machine is not anonymising traffic. That distinction matters for what you do next. A signup from here is worth a second look because automation lives on networks like this one, but blocking the range outright also blocks every monitoring service, payment webhook and corporate proxy that runs on it.
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.
