Summary
Verizon Business (UUNET)
tier-1 transit isp legacy
One of the largest and oldest Tier 1 backbones on the internet — the former UUNET / MCI network, now Verizon Business (UUNET, AS701).
What it's used for
- Global IP transit and enterprise connectivity: Verizon's business/wholesale backbone plus a large US business-access footprint.
- Reaches the entire internet without buying transit (Tier 1).
Notable
- Carries an enormous amount of address space and appears in a large share of internet routing paths — a core network other networks depend on.
- Verizon splits its backbone across regional ASNs; AS702 covers Europe and AS703 Asia-Pacific, all descended from UUNET.
Interesting
- UUNET was one of the first commercial ISPs (founded 1987) and helped privatize internet access as the NSFNET era ended.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
17 upstream, 1,136 downstream and 1,145 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 2026-11-02, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 448 networks and 1,851 prefixes, as published 2026-11-03. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
