AS3215

AS3215 is the domestic IP backbone of Orange S.A. (formerly France Telecom), the incumbent French operator, and it is primarily an eyeball-and-mobile network for French consumers and enterprises. The RIPE aut-num explicitly describes it as Orange's IP backbone for enterprise and French consumers, and route-intelligence tools tag it as a home ISP, a mobile data/carrier network, and anycast-bearing. Community rankings place it among the top networks by estimated eyeballs (around #15 globally and #1 in France) and roughly #20 by originated IPv4 space; it announces on the order of 913–949 IPv4 prefixes (about 20 million addresses) and a small IPv6 set. A useful structural detail for triage: Orange's *international* transit and peering ride on a separate ASN, AS5511 (Opentransit), which feeds AS3215 domestically — so AS3215 is the access/backbone for France while the global carrier role sits under AS5511. Other related ASNs include AS25186 (Transpac, transit/VPN) and AS28708 (the OrangeFR portal). Orange had a notable RPKI misconfiguration in November 2018: per an FRnOG mailing-list report, AS3215 began announcing /17 prefixes for space whose ROAs had a maxLength of 16, making roughly 960 /24s RPKI-invalid and reducing their visibility; the issue was subsequently resolved, and in the current view only a couple of invalids remain. For triage, a 3215 address is typically a French Orange consumer, business, or mobile subscriber, with residential dynamic-IP and mobile carrier-NAT caveats.

Security/abuse context

mixed eyeball + mobile + backbone. French residential dynamic-IP and mobile carrier-NAT shared-IP caveats apply. November 2018 RPKI misconfiguration: AS3215 announced /17s for space with ROA maxLength 16, making ~960 /24s RPKI-invalid/unreachable (per FRnOG report by nusenu, 2018-11-16), since resolved (now ~2 invalid observed).

Analyst note

A 3215 IP is typically a French Orange consumer/business/mobile subscriber; Orange's international transit is under AS5511, not 3215.
