What is an IP address?
An IP address is the unique "address" of each device on a network; servers and devices find each other by it. There are two versions: the older IPv4 and the newer IPv6.
Key differences
| Criterion | IPv4 | IPv6 |
|---|---|---|
| Format | 192.0.2.1 | 2001:db8::1 |
| Address count | ~4 billion | Practically unlimited |
| Status | Running out | The future |
Why IPv6 appeared
IPv4 addresses (~4 billion) ran out as the internet grew. IPv6 provides practically unlimited addresses and is built for modern networks. But IPv4 is still needed for compatibility with older systems.
Why a server needs both
Today some networks use IPv4, others IPv6. With both (dual-stack), your site is reachable by everyone. Epro.io provides IPv4 + IPv6 on all VPS and servers, with RIPE NCC LIR status and its own IP resources.
