IPv4 + IPv6: Why Your VPS Needs Both
Your VPS needs an IP address to be reachable — and there are two kinds. Here's why having both IPv4 and IPv6 matters, in plain terms.
The short version
- IPv4 — the old, familiar address (like 203.0.113.5). The internet ran out of fresh ones years ago, so they're scarce and valuable.
- IPv6 — the newer, effectively unlimited address space. More and more networks use it.
Some clients connect over IPv4, some over IPv6. To reach everyone, your server should speak both.
Why a dedicated IPv4 still matters
Despite IPv6 growth, huge parts of the internet still reach out over IPv4 — many home networks, older systems, and some corporate setups. A dedicated IPv4 ensures anyone can connect, and it's cleaner for running mail, web and APIs than a shared address.
Why free IPv6 is a nice bonus
IPv6 gives you a large block of addresses at no extra cost — handy if you host many services or containers, each wanting its own address. It's also increasingly expected by modern apps and CDNs.
