Unclassified ARIN
Summary
Google LLC
hosting government infrastructure
The handle names a private cloud product, and every block belongs to somebody else.
What it's used for
- A cloud provider's network. Four IPv4 prefixes announced from the United States, no IPv6, one thousand and twenty-four addresses, through four observed BGP neighbours.
Notable
- The AS handle joins the holder's name to the words private and cloud, and the name appears on none of the four blocks.
- One block is registered to a national ocean and atmosphere agency, under a netname joining its initials to the name of its own wide-area network.
- Two more belong to a national patent and trademark office and share a single netname: the office's initials and the word for a network.
- The fourth netname is not a name. It is the first and last address of the range with spaces around a hyphen, and its registrant is a carrier's pool of customer addresses.
- Three of twelve queried addresses answered. Each writes the address backwards, then a word meaning fixed, then a word meaning one address answered from many places, then that carrier's domain under a two-letter country suffix.
Interesting
- A cloud provider's AS number carrying government blocks is what a direct interconnect looks like from the routing table. The addresses stay the agency's; the announcement is the provider's.
- The backwards address is the raw form of a reverse-DNS query leaking into the answer: whoever generated the zone used the lookup name and never turned it back round.
- Four blocks, three registrants, none of them the holder. The handle is the only field that agrees.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
4 upstream, 0 downstream and 4 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.
