Unclassified ARIN
Summary
cloud infrastructure business global
GOOGLE-2 is operated by Google LLC.
What it's used for
- The address space carries Google Cloud infrastructure, evidenced by netnames
GOOGLE-CLOUDand reverse DNS entries pointing togoogleusercontent.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.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
19 upstream, 1 downstream and 35 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 443 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
