Summary

Orange (OpenTransit)

Global · AI-generated

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.

Classification and threat

Transit Tier-1 or major backbone carrying other networks’ traffic.

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 1,772 prefixes, as published 2026-10-15. 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.
