When you sign up for hosting, your website is usually placed on a shared IP address: one IP address serving many different websites on the same server. A dedicated IP gives your website its own address that no other account uses. For the vast majority of small business websites, a shared IP works perfectly well, and paying extra for a dedicated one solves a problem you don't have.
What Shared IP Hosting Means
On a shared IP, the server tells visitors' browsers which website to load using the domain name in the request, not the IP address alone. This is how nearly all modern shared hosting works, and it's why one server can host hundreds of unrelated websites without any conflict. Your site loads exactly as fast and behaves exactly the same as it would on a dedicated IP.
What Dedicated IP Hosting Means
A dedicated IP is an address assigned only to your hosting account. No other website on the server answers on that IP. It doesn't make your site faster or more secure by itself. What it changes is how your server is identified independently of your domain name, which matters for a small number of specific use cases.
When You Might Actually Need One
- Sending high volumes of email. If your business sends a large amount of outbound email (newsletters, transactional receipts, automated notifications) a dedicated IP means your email sending reputation isn't affected by what other accounts on a shared IP are doing.
- Running your own mail server with strict PTR requirements. Some email deliverability setups need a dedicated IP so its reverse DNS (PTR) record matches your domain exactly.
- Software that requires a raw IP connection. A small number of older payment gateways, licensing systems, or third-party integrations require a fixed IP address rather than a domain name.
- Accessing your site directly by IP during DNS changes. This is a temporary convenience, not a real long-term reason to keep a dedicated IP.
Common Myths About Dedicated IPs
Two myths come up often, and neither is true anymore:
- “A dedicated IP improves SEO.” Search engines rank websites on content, links, and technical performance, not on whether the IP is shared or dedicated.
- “You need a dedicated IP to install an SSL certificate.” This used to be true years ago, but modern browsers and servers support a technology called SNI that lets multiple SSL certificates run correctly on a single shared IP. Your certificate will install and work the same either way.
If your only reason for wanting a dedicated IP is “just in case” or something you read online, it's very likely you don't need one. Keep the cost and only upgrade when a specific requirement, like the ones above, actually applies to you.
How to Get a Dedicated IP on Your Hosting Plan
Dedicated IPs are not usually self-service on shared hosting. Open a support ticket with your hosting provider explaining why you need one (for example, an email sending reputation issue or a specific software requirement). Support will confirm availability on your plan and assign the IP to your account, then let you know once it's active so you can update any records that depend on it.
If your reason for considering a dedicated IP is email deliverability, it's worth reading about PTR records and reverse DNS first, since that's usually the actual setting that needs to change.
