Datacenter vs ISP proxies: what the extra cost buys

Both are static IP addresses running on servers, rented per IP each month, and both are fast. The difference is who the address is registered to: a datacenter IP belongs to a hosting company, so a site can see it is a server; an ISP IP belongs to a home internet provider, so it looks like a household connection. That registration is what the higher ISP price buys. If your target accepts server addresses, datacenter IPs do the same job for less.

What a site can see

Every IP address belongs to a network, and public registries say whose network it is. A site can look up an address and learn that it belongs to a hosting or cloud company rather than a broadband provider. Many sites do not care. Some treat hosting networks with suspicion, ask for more checks, or refuse them, because ordinary visitors do not browse from servers.

An ISP proxy avoids that particular signal: its address is registered to a consumer internet provider even though it is hosted in a data center. The hosting is the same: both run on servers rather than someone’s home connection, and both are yours for the rental. How fast and how reliable a given plan is depends on the provider, not on which of the two it is.

How they are sold

The box above prices 10 IPs of each for a month. Shared datacenter lists can cost a few cents per IP; the per-IP price of dedicated datacenter IPs sits closer to ISP prices, so compare like with like. Both comparisons let you require shared or dedicated IPs under “Refine”: datacenter and ISP.

Which one to buy

Choose datacenter when the target accepts server traffic: public data, APIs, your own sites, search and price checks on sites that do not screen networks. Start with a small package and a refund window, test it on your targets, and only move up if it fails.

Choose ISP when a target treats hosting networks differently from home ones, and you still need a fixed, fast address: accounts you manage over time, allowlisted connections, long sessions. If you need addresses that change rather than stay, rotating residential traffic is the other option (ISP vs residential proxies).

Whichever you pick, check what the IP price includes: how much traffic per IP, how many threads or connections, and whether the IPs are yours alone. Per IP or per GB explains when an IP plan beats a traffic plan.
