Dedicated IP vs shared IP: what’s the difference?

When you connect through a VPN, a proxy or a hosting provider, the websites you visit don't see your address. They see the provider's. So the useful question isn't "do I have an IP?", it's "how many other people appear behind the same IP?"

That is the whole difference between a shared IP and a dedicated IP. This post walks through what each one means, the trade-offs, a few common myths, and a quick way to decide.

TL;DR

What is a shared IP?

A provider runs servers with a limited pool of addresses and a lot of customers. At any moment, many of them leave through the same address. To a website, all of that traffic comes from one place.

Why people like it

• It's cheaper, because the cost of the address is split across many people.
• Switching regions is easy: you just pick another server.
• You blend into a crowd, so no single person stands out.

Where it hurts

• Neighbors affect you. If someone else on the same address triggers a spam filter or a login check, your traffic can be treated with suspicion too. You'll notice it as more captchas or the occasional blocked page.
• You can't allowlist it. If a server or partner only accepts specific source addresses, a shared address is a poor fit, because it can be used by others and may not be the same next time.
• Some services keep lists of well-known shared VPN ranges and treat them more strictly.

What is a dedicated IP?

A dedicated IP is assigned to a single customer. For as long as your plan is valid, the address stays the same, and nobody else is behind it.

Why people like it

• Allowlists just work. You give a server, cloud console or partner one address, once, and it keeps working.
• A consistent identity. Sign-in checks that compare where you connect from see the same source every time, which makes your own access easier to reason about and audit.
• Reputation is yours. There are no neighbors, so what happens on that address is down to you.
• Easier troubleshooting. When you integrate with a third-party API that restricts source addresses, a predictable address is much easier to debug.

The trade-offs

• It usually costs more, because you're paying for an address that is reserved for you.
• A stable address is also a stable identifier. If you're after privacy through blending in, a dedicated IP does the opposite.
• It tends to be tied to one region. If you want to hop between countries all day, a shared pool is more convenient.
• If it ever gets flagged, there's no crowd to hide in. The reputation is entirely yours.

"Dedicated" and "residential" are different questions

This is where people mix things up. Who shares the address and what kind of network it comes from are two separate choices.

• Datacenter: an address from a hosting provider's network.
• Residential: an address from a residential network.
• ISP residential: an address from an ISP's home broadband network.

You can have a dedicated datacenter IP, a shared residential IP, and so on. Some services do treat these network types differently, but every platform sets its own access policy, so no address type is a guarantee that something will or won't work.

When should you pick which?

A shared IP is usually enough when you:

• browse, stream or work on everyday tasks and don't care which address you get;
• want to switch regions freely;
• are on a budget or only need it for a short while.

A dedicated IP is worth it when you:

• need to allowlist your own address on servers, cloud consoles, firewalls or a partner's system;
• connect to a company back end or remote desktop that only trusts specific source addresses;
• integrate with APIs that restrict source IPs;
• manage accounts or tools where a constantly changing sign-in location is a hassle;
• want one consistent address to show up in your access logs.

Four common myths

"A dedicated IP is faster." Not by itself. Speed depends on the route, the distance, and how busy the server is. A dedicated address makes things stable, not fast.

"A dedicated IP is more anonymous." Usually the opposite. One address that only you use is a very consistent fingerprint. Dedicated is about control and stability, not hiding.

"A dedicated IP means I won't get blocked." No. An address's reputation is only one signal among many, and each platform decides for itself what it accepts.

"It's the same as my home static IP." Related, but not the same. A static IP at home belongs to your own internet line. A dedicated IP from a VPN or proxy provider is reserved for you but sits on the provider's network, in whichever region you chose.

How to check what you actually have

From a terminal, two commands tell you a lot:

# The address websites see curl -s https://api.ipify.org # Who owns it: look at the "org" field (the ASN and organization) curl -s https://ipinfo.io/json 

A few things to look at:

• The org field tells you which network it belongs to. A hosting company suggests a datacenter address; a consumer ISP name suggests a residential or ISP residential one.
• Run it on different days. If the address never changes, it's effectively static for you.
• You can't tell from your side alone whether others share it. If that matters, ask your provider directly.

Wrapping up

• Shared = many people, one address. Cheap and flexible, but you inherit your neighbors' reputation and can't rely on the address.
• Dedicated = one customer, one address. Stable and allowlist-friendly, but pricier and easier to link to you.
• Datacenter vs residential vs ISP residential is a separate choice. Decide each question on its own.

Pick the one that matches the job: flexible and cheap for everyday use, dedicated when the address itself has to stay put.

Disclosure: I work on AnboVPN, which offers both shared IPs and dedicated IPs (residential or ISP residential). Each type has its own data pool. Nothing above depends on that, so choose based on your own use case. If you want to look at an address's ASN, ISP and network type, we also have a free IP lookup tool.

What do you use a dedicated IP for? I'd love to hear which cases I missed in the comments.
