Summary
Verizon Business (former ANS backbone)
transit legacy
A legacy backbone allocation (ANSBB-ASNNET-1) now held by Verizon Business. The ANSBB handle traces to Advanced Network and Services (ANS), the operator of ANSNET.
What it's used for
- Carrier/transit routing within the Verizon Business network.
Notable
- ANS built ANSNET, the T3 backbone behind the NSFNET Backbone Service in the early 1990s. Its networking business moved to AOL, then WorldCom, MCI, and ultimately Verizon.
Interesting
- One of a small block of
ANSBBautonomous systems (AS1325 and siblings) carried forward from the NSFNET-era backbone.

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.
