Yes, you still have a private IP address, but you do share public IPv4 addresses with other users. This can cause problems, like if your Starlink IPv4 address gets blocked by an online service because someone else has used it for illegal activities or poor behavior. It can also cause issues for gamers as they can't host a server for gaming. A VPN can help with these problems because it lets you easily switch to a different public IP address if you encounter a block. The reason that Starlink users share IP addresses is because — for Standard customers (other than Starlink Business) — Starlink assigns public IPs through a system called CGNAT (Carrier-grade NAT). Unlike regular ISPs, CGNAT uses a shared pool of public addresses. IPv4 addresses are very scarce, and smaller networks can’t afford to offer a dedicated one for each customer (like normal ISPs do). CGNAT helps Starlink efficiently manage its address resources.
