Dedicated IP vs shared IP: do you need a dedicated IP address?

The short answer

An IP address is the numeric address of a server, such as 203.0.113.10. With a shared IP, many websites on the same server answer on one address, and the server uses the domain name in each request to decide which site to show. With a dedicated IP, the address belongs to your server or account alone.

For most business websites, the shared hosting debate about dedicated IPs is settled: a shared IP works, including for HTTPS. A dedicated IP becomes necessary when something outside your website has to recognise your server by its address.

Dedicated IP vs shared IP at a glance

Factor	Shared IP	Dedicated IP
Who uses the address	Many sites on the same server	Only your server or account
Typical hosting type	Shared hosting	VPS, dedicated server, or a paid add on
HTTPS / SSL	Works, using SNI	Works
Open the site by typing the IP	Usually not	Yes, if you configure it
Fixed address for API allowlists	Not suitable: the address is shared and can change if accounts move	Suitable
Outgoing email reputation	Shared with other senders on that IP	Yours alone, good or bad
Cost	Included	Included with VPS and dedicated plans, or extra

Why SSL no longer needs a dedicated IP

Older advice said every HTTPS site needed its own IP address. That was true before browsers widely supported Server Name Indication (SNI), an extension to TLS. RFC 6066 describes its purpose: clients tell the server which name they want so that one network address can host several "virtual" servers securely. The server then presents the right certificate for that name.

Every current browser supports SNI, so a shared IP can serve many HTTPS sites, each with its own certificate. If a provider still tells you a dedicated IP is required for SSL on a normal website, ask why. Our guide to how SSL certificates work covers the handshake in more detail.

When you genuinely need a dedicated IP

Payment gateway, bank or government API allowlists

Some banking, payment gateway, logistics and partner APIs only accept requests from IP addresses you register with them in advance. On shared hosting, your outgoing requests leave from an address shared with other accounts, which you cannot register as yours, and which may change if the host moves accounts between servers. A VPS with a dedicated IP gives you a stable address to put on the allowlist.

Running your own mail server

If your server sends email directly, the reputation of its IP address matters. Google's sender guidelines state that the activity of any senders using a shared IP address affects the reputation of all senders on it. They also require the sending IP to have a matching reverse DNS (PTR) record that resolves to a hostname. On a server you run, you need a dedicated IP to control both.

For an ordinary office using hosting mailboxes or a service such as Zoho Mail or Google Workspace, this does not apply to you directly; the provider manages its sending IPs. If mail is landing in spam, start with fixing emails going to spam.

Direct server access and custom services

Developers often need a fixed address for SSH, database connections from an office, a VPN, or services on custom ports. Those are VPS tasks, and a VPS comes with its own IP for exactly this reason. The what is a VPS guide explains what else changes when you move to one.

Firewall rules at a client's office

Some corporate clients only allow their staff to reach approved IP addresses, or need to allow your server through their firewall. A dedicated IP gives them a single address to approve.

Myths about dedicated IPs

• "A dedicated IP improves SEO." Search engines rank pages on their content and quality. Sharing an IP is the normal arrangement for shared hosting, so moving to a dedicated IP is not a ranking strategy.
• "A shared IP makes my site slower." Speed depends on the server's resources and your site, not on how many names share an address. See how to improve website speed for the real levers.
• "A neighbour's bad site will get mine blocked." Rarely, a whole IP lands on a blocklist because of another account. A good host handles this, and HTTPS sites are reached by name, so ordinary visitors are not usually affected. Outgoing email is the area where shared reputation matters most.

What a dedicated IP costs in practice

Public IPv4 addresses are scarce, so hosts usually reserve dedicated addresses for VPS and dedicated servers, or charge extra for one on shared hosting. When you compare offers, check whether the IP is included in the plan price, whether it is IPv4 or IPv6, and whether it stays the same for the life of the service.

ODHOST note: ODHOST VPS plans, on servers located in India, include one dedicated IPv4 address, starting with OD-VPS Nano (2 GB RAM, 1 vCore, 40 GB storage) at ₹699 a month. Dedicated servers, from ₹11,499 a month, also include one dedicated IPv4 address. ODHOST shared plans do not list a dedicated IP, so open a support ticket if you have a specific need on shared hosting. Yearly billing is 12 times the monthly price, and applicable taxes are shown at checkout.

Developer notes: checking your IP setup

To see which IP your domain resolves to, and whether other sites share it, use a DNS lookup:

# Which IP does the domain point to?
dig +short yourbusiness.in A

# Which IP do outgoing requests from your server use?
curl -s https://ifconfig.me

The second command matters for API allowlists, because a server's outgoing address is not always the same as the address your domain points to. Run it on the server itself and register that value with the API provider.

Which should you choose?

• A clinic or CA firm website with an enquiry form: a shared IP on shared hosting.
• A WooCommerce store using a standard payment gateway plugin: usually a shared IP; check the gateway's documentation, as most hosted checkouts do not need an allowlisted server IP.
• A startup whose backend calls a bank or payment API with IP allowlisting: a VPS with a dedicated IP.
• A developer running a custom mail server for transactional email: a dedicated IP with reverse DNS set up, and careful SPF, DKIM and DMARC.
• An agency hosting many brochure sites: shared IPs are fine; move individual clients to a VPS only when one of the needs above appears.
