Unclassified ARIN
Summary
Pitney Bowes Incorporated
enterprise legacy
PITNEYBOWES-AS-1 is the corporate autonomous system of Pitney Bowes Incorporated, the American shipping, mailing and e-commerce logistics company. It is an enterprise network: the prefixes are registered to Pitney Bowes' own handles (PBFS, PB-EUROPE) and to legacy UUNET customer-assignment space (UU-G1), not to unrelated third parties.
What it's used for
Pitney Bowes' own internet presence and, given the business, the externally reachable side of its mailing, shipping and postage platforms — the systems customers and franking machines talk to. The AS announces 15 IPv4 prefixes (~4,352 addresses), no IPv6, and shows 5 observed neighbours in RIS: a small multihomed upstream set, consistent with a company that buys transit at a handful of sites rather than peering as a carrier.
Notable
The prefix registrations fall into three families, all of them still Pitney Bowes. PBFS covers the bulk of the network — the 199.231.32.0–199.231.50.0 /23s and /24s, the company's own ARIN space. UU-G1 covers 206.136.84.0/24, 206.136.86.0/24 and 206.136.87.0/24, assignments out of the old UUNET customer pool and a fingerprint of a corporate network that was connected in the UUNET era and never renumbered. PB-EUROPE covers 193.242.234.0/24, a RIPE-registered block for the European side of the business.
Interesting
Space split across two RIRs under several different registrant handles is exactly the surface pattern that flags an address broker or a leasing operation. Here it is nothing of the sort: every registrant resolves back to the same real, findable company or to its historical upstream. The lesson generalises — the discriminator is who the registrants are, not how untidy the inventory looks.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, 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: 442 networks and 1,778 prefixes, as published 2026-10-20. 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.
