The Euskaltel IPv4 Crisis. Euskaltel, like many European ISPs, has exhausted its IPv4 address pool. If you have a standard residential contract, you are likely behind CG-NAT.

Your ZTE F6640 does not receive a unique Public IP address from the Euskaltel BRAS (Broadband Remote Access Server). Instead, it receives a private IP (often in the 10.x.x.x range) shared by hundreds of other customers.
