AS19527 announces 119 IPv4 prefixes covering 868,352 addresses and 34 IPv6 prefixes.

About this network

GOOGLE-2 is operated by Google LLC.

What it's used for

• The address space carries Google Cloud infrastructure, evidenced by netnames GOOGLE-CLOUD and reverse DNS entries pointing to googleusercontent.com.
• With 903680 IPv4 addresses announced across 125 prefixes and only 22 observed neighbours, the high address-to-neighbour ratio indicates a large-scale internal corporate estate rather than a transit or access network.

Notable

• All registrants in the sample are Google LLC, matching the AS holder and confirming consistent ownership of the announced space.
• The inventory is finely subdivided into 125 IPv4 prefixes and 43 IPv6 prefixes, reflecting site-by-site segmentation typical of a major cloud provider's internal network architecture.
• The largest prefixes include 34.114.0.0/15 and 34.188.0.0/15, both registered under the netname GOOGL-2.
