Paris or Rennes, the same verdict
What a French connection looks like from outside
Paramount+ reads the public address a request arrives from, and every consumer connection in France supplies a French one. Paris, Marseille, Lyon, Toulouse, Nice, Nantes, Montpellier, Strasbourg, Bordeaux, Lille, Rennes, Reims and Toulon all return the same country. The city has never been the variable.
The variable is your operator, and in France that question has changed recently enough that older articles get it wrong. Free, SFR and Bouygues shared IPv4 addresses first. Orange began in January 2025. There is now no major French consumer network on which an ordinary subscriber can simply assume an address of their own.
Fibre and DSL
Orange, Free, SFR, Bouygues Telecom
Together they carry the overwhelming majority of French homes, and all four now share IPv4 among subscribers. Free is the useful exception: it will assign a fixed IPv4 address on request, at no cost, from the Freebox management console.
Mobile and tethering
Orange, Free Mobile, SFR, Bouygues and the resellers
A French address, shared as a matter of course, and about 83% of French mobile lines are IPv6-enabled. If a test behaves differently over 5G than over your box, the protocol difference is the first thing to suspect.
Operator TV and the second box
Freebox Player, Livebox TV, SFR Box, Bbox
These sit on the same line and answer with the same French address, but they are configured separately from your computer. A change made on one does not follow to the other, which is a frequent source of “it works on my laptop” confusion.
Office, campus, hotel, SNCF
Corporate networks, universities, hotel Wi-Fi, on-board Wi-Fi
A French address, and many of these block tunnelling protocols as policy. A failure here is a fact about that network. It says nothing about your account or about Paramount+.
On the arithmetic: France holds roughly 1.24 public IPv4 addresses per person — below the United Kingdom and Germany, well above Spain, and far below the United States at about 4.7. That is not a crisis, and the French move to shared addressing is better explained by how far IPv6 has gone here. When 94% of lines can use the replacement, sharing the original stops hurting.
