Every device on the internet needs an IP address, and most of them still use IPv4 — a 32-bit format that allows about 4 billion addresses. But we’re running out of them fast.

That’s why IPv6 was introduced. It’s a newer system with a 128-bit format, allowing trillions of unique addresses. It’s the future of internet communication — and many modern servers now support it.

For website owners, this switch means better performance, faster routing, and support for growing traffic. IPv6 is also more secure and efficient in how it handles connections.

Some older hosting setups still use only IPv4, so if you’re planning long-term, it’s smart to choose a host that supports both. It keeps your site future-proof.
