Do I need a dedicated IP? An honest answer
Dedicated IPs get oversold. Here's when one genuinely helps — mail, SSL, control — and when a shared IP is perfectly fine for your project.
"Do I need a dedicated IP?" is a question where the honest answer is often *no* — but sometimes it's a clear *yes*. Dedicated IPs get oversold as a must-have upgrade when they're really a targeted tool. Here's a straight look at when one earns its keep and when a shared IP is completely fine.
Shared vs dedicated: the difference
- A shared IP is used by multiple sites or customers at once. The server routes requests to the right site by hostname. This is normal and works well for the vast majority of websites.
- A dedicated IP is assigned to you alone. Traffic on that IP is yours and nobody else's.
Modern web serving handles many sites on one IP effortlessly, which is why shared IPs are the default and usually invisible to visitors.
When a dedicated IP genuinely helps
There are real, specific cases where a dedicated IP matters:
1. Sending email at scale. Your IP's reputation affects whether your mail reaches inboxes. On a shared IP, a bad neighbour's spam can drag down deliverability for everyone on it. If email is important to you — transactional mail, newsletters, business correspondence — a dedicated IP gives you a clean reputation you fully control (paired with proper SPF, DKIM and DMARC).
2. You need reverse DNS (PTR) control. Mail servers check that an IP's reverse DNS matches the sending domain. Setting a PTR record requires control of the IP, which means a dedicated one. This is essentially a subset of the email case, but it's the concrete technical reason.
3. Running your own services on fixed ports. Game servers, VPNs, custom TCP services and anything where clients connect directly to an IP benefit from a stable, dedicated address you won't share or have reassigned.
4. IP allowlisting. If a partner, API or corporate firewall needs to allow *your* server's IP specifically, a dedicated IP gives you a stable value to hand them that won't change under you.
5. Compliance or client requirements. Occasionally a contract or standard simply requires a dedicated IP. If so, that settles it.
When you almost certainly don't need one
For most sites, a shared IP is genuinely fine:
- A normal website or blog. Browsers connect by hostname; visitors never see or care about the IP.
- HTTPS. The old myth that SSL requires a dedicated IP is long dead — SNI lets many HTTPS sites share one IP, and free Let's Encrypt certificates work perfectly on shared IPs.
- SEO. A dedicated IP does not improve search rankings. This is a persistent myth; ignore it.
The honest summary
Get a dedicated IP if you're sending meaningful email, need PTR/reverse DNS control, run direct-connect services like game servers or VPNs, or must satisfy an allowlist or compliance requirement. Otherwise, a shared IP does everything a typical website needs — including HTTPS — and skipping the dedicated IP saves money with no downside.
How Nxeon handles it
Nxeon offers a dedicated IP as an option, not a forced default, which is the honest way to sell it. Start on a shared IP if your project doesn't need more; add a dedicated IP when you have a concrete reason — running mail, a game server, or a service that needs a stable, reputation-clean address you fully control. Pay for it when it helps you, not before.
