What Additional IPv4 Addresses Are Actually For

Every KVM VPS ships with one IPv4 address included. You can buy more via the VPS add-ons — but what do you actually need a second (or third) IP for?

Real Use Cases

• Multiple websites, each with their own SSL on port 443. Without SNI (which most modern setups handle fine with a single IP, to be fair) or with software that doesn't support it well, each HTTPS site traditionally wants its own IP:443 binding.
• A dedicated mail-sending IP. If you're running your own outbound mail server, keeping it on a separate IP from your web traffic protects your web services' reputation if the mail IP ever gets flagged, and vice versa.
• Running multiple isolated services that each expect to own port 80/443/25/whatever — instead of juggling reverse-proxy routing rules, each service just gets its own IP and binds normally.
• IP-based access control or licensing — some software licenses or firewall setups are tied to a specific IP; a second address lets you run that alongside other services without conflict.
• Separating a game server's network traffic from your web/admin services, if you're running both on one VPS and want them fully independent at the network level.

What It's Not For

An additional IPv4 address does not give you more bandwidth, more performance, or extra allocations for a game panel server (that's a completely different system — see our network tab guide for game server allocations specifically). It's purely a second real, routable IP address bound to your VPS.

How to Get One

From your VPS service's Upgrade page, add the "Additional IPv4 address" option in the quantity you need — see current pricing. It's billed monthly alongside your VPS.

Setting It Up Inside the VPS

Once purchased, the new IP is assigned at the hypervisor level — you'll typically need to configure it inside the VM's own networking (via netplan on Ubuntu, or your distro's equivalent) so the OS actually knows to use it, unless it's handed out automatically via DHCP depending on your VPS's network mode. Check your service's network details for the exact IP/gateway/subnet to configure.

IPv4 Scarcity, Briefly

IPv4 addresses are a genuinely limited resource globally (the internet ran out of fresh allocations years ago) — that scarcity is reflected in pricing across every serious hosting provider, not just us. If you don't have one of the specific needs above, a single IP is almost always enough.
