Summary
Orange (OpenTransit)
tier-1 transit backbone
Orange's international IP backbone (OPENTRANSIT) — the global Tier 1 transit
network of the French telecom group Orange.
What it's used for
- Global IP transit and wholesale connectivity, interconnecting Orange's national operators (France and across Africa and the Middle East) with the rest of the internet.
Notable
- A Tier 1: reaches the whole internet through settlement-free peering.
- Distinct from AS3215 (Orange's France consumer/broadband network) — 5511 is the international carrier backbone.
Interesting
- Orange's strong footprint in Africa makes OpenTransit a common path onto and off of the continent.
