Dedicated IP vs shared IP in web hosting: which should you choose?
Nicolas,
When choosing a web hosting plan, a technical question often comes up: should you opt for a dedicated IP or a shared IP? This decision may seem secondary, but it has real implications for your email deliverability, your site's security and, in some cases, your search engine rankings. Here is everything you need to know to make the right choice.
What is an IP address in web hosting?
Every website hosted on a server is accessible via an IP address — a series of numbers that identifies the server on which it is hosted. Depending on the type of hosting chosen, this IP address can be exclusive to your site (dedicated IP) or shared between multiple sites hosted on the same server (shared IP).
The vast majority of shared hosting plans use shared IP addresses, which allows hosting providers to reduce their costs and offer low-price plans. Dedicated IPs are generally reserved for VPS hosting, dedicated servers, or available as an option on some premium shared hosting plans.
Shared IP: how it works and what it means
On a standard shared hosting plan, your website shares the same IP address with dozens or even hundreds of other sites hosted on the same server. This means that:
- If another site on that IP is flagged as spam or malicious, your site may suffer indirect consequences
- Server resources (CPU, RAM, bandwidth) are shared between all sites
- The cost is lower because infrastructure expenses are pooled
- Management is simplified because the hosting provider handles everything
Key takeaway: a shared IP does not mean that your site's data is accessible to other sites on the same IP. Each site remains isolated and secure — only the network IP address is shared.
Dedicated IP: how it works and its advantages
With a dedicated IP, your site has its own exclusive IP address, not shared with any other sites. This is the default on VPS and dedicated servers, or available as a paid option on some shared hosting plans.
The advantages of a dedicated IP are numerous:
- Independent email reputation: your IP address is not affected by the sending practices of other sites
- Direct IP access: your site is accessible directly via its IP address, without relying on DNS
- Simplified SSL certificates: some older systems require a dedicated IP for SSL certificates (less relevant today with SNI)
- Better control: you have full control over your IP address's reputation
Dedicated IP vs shared IP: full comparison
| Criteria | Shared IP | Dedicated IP |
|---|---|---|
| Price | Included in hosting | Paid option (usually $2-5/month) |
| IP reputation | Shared with other sites | Entirely under your control |
| Email deliverability | Can be affected by neighbours | Excellent if properly configured |
| SEO | Minimal impact today | Minimal impact today |
| Security | Indirect risk if neighbour blacklisted | Risk isolated to your site only |
| Direct IP access | No (redirects to host page) | Yes |
| SSL/HTTPS | Compatible (thanks to SNI) | Compatible |
| Best for | Showcase sites, blogs, small sites | E-commerce, bulk email sending, pros |
Does a dedicated IP improve SEO?
This is one of the most debated questions in the world of SEO. The short answer is: no, a dedicated IP does not directly improve your Google ranking.
Google has confirmed on multiple occasions that sharing an IP between multiple sites does not affect the individual ranking of each site. Google's algorithms evaluate each site based on its own content, backlinks and usage signals — not based on the server's IP address.
However, if your site shares an IP with spammy or malicious sites that have been blacklisted, there could be an indirect impact on your online reputation — although this scenario is rare with reputable hosting providers who actively monitor their servers.
Good to know: if SEO is your only motivation for getting a dedicated IP, save your money. Invest instead in quality content, relevant backlinks and optimised page load speed — these factors have a far more significant SEO impact.
Dedicated IP and email deliverability: the real advantage
It is in email deliverability that a dedicated IP makes a real difference. If you send newsletters, transactional emails or marketing campaigns from your own mail server, the reputation of your IP address is crucial.
On a shared IP, if another site hosted on the same IP sends spam, your IP address could end up on blacklists used by email providers to filter spam. The result: your own legitimate emails may end up in the spam folder or be rejected entirely.
With a dedicated IP, you are solely responsible for your sending reputation. If you follow best practices (SPF, DKIM, DMARC, opt-in list...), your deliverability will be optimal.
Who really needs a dedicated IP?
A dedicated IP is recommended if...
- You send emails in volume from your own server (newsletters, transactional emails)
- You run an e-commerce site with sensitive transactions
- You need to access your server directly by IP (development, testing)
- You want full control over your IP address's reputation
- You are in a sensitive sector where online reputation is critical
A shared IP is enough if...
- You run a blog, showcase site or small site with no bulk email sending
- You use a third-party service for your emails (Brevo, Mailchimp, Mailgun...)
- Your budget is limited and you are just starting out with website creation
- Your main goal is simply to get a site online quickly
Dedicated IP and SSL certificate
Historically, a dedicated IP was required to install an SSL certificate on a website. This is no longer the case since the widespread adoption of the SNI (Server Name Indication) protocol, which allows multiple HTTPS sites to coexist on the same IP address.
Today, all reputable hosting providers offer free SSL certificates via Let's Encrypt, compatible with shared IPs. The SSL argument for justifying a dedicated IP has therefore become obsolete in the vast majority of cases.
How to check if your IP is on a blacklist?
If you use a shared IP and notice email deliverability issues, you can check whether your IP address is blacklisted using tools such as:
- MXToolbox (mxtoolbox.com) — checks your IP against over 100 blacklists
- Spamhaus (check.spamhaus.org) — one of the most respected blacklists
- MultiRBL — aggregates results from many blacklists in a single check
Dedicated IP or shared IP: which to choose in 2026?
For the vast majority of websites — blogs, showcase sites, small e-commerce stores using third-party email services — a shared IP is perfectly adequate. Modern hosting providers actively monitor their servers to prevent malicious sites from compromising the reputation of their shared IPs.
On the other hand, if you run your own mail server, a sizeable e-commerce operation or have advanced control needs, investing in a dedicated IP is a wise choice — especially since the additional cost is generally modest ($2 to $5 per month).
Good to know: regardless of your hosting configuration, your server's IP address is one of the publicly visible pieces of information about your site. It can reveal your hosting provider, your hosting country and in some cases other sites hosted on the same IP.
