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.
