Summary

Verizon Business (former ANS backbone)

United States · AI-generated

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 ANSBB autonomous systems ([AS1325](https://asn.ipinfo.app/AS1325) and siblings) carried forward from the NSFNET-era backbone.
