The short answer
The three proxy types differ in two ways that matter when you buy: who the IP address is registered to, and whether it stays the same. Residential and ISP addresses belong to internet service providers, the same kind of networks that home connections use. Datacenter addresses belong to hosting providers. Rotating Residential changes the address for you, while Static ISP and Datacenter give you a fixed address for a set term.
For accounts you sign in to every day, such as a store, an ad account or a social page in an antidetect browser, a fixed ISP address is usually the right fit. For price monitoring and scraping across many pages, rotating residential traffic spreads your requests over many addresses. Datacenter is the budget option for monitoring, testing and API work on sites that do not mind datacenter traffic.
How the three types compare
This is how the three products work at IPMusk. Other providers may package them differently, so check the billing model before you compare prices.
| Rotating Residential | Static ISP | Datacenter | |
|---|---|---|---|
| IP source | Addresses on residential networks | Addresses registered to internet service providers | Addresses registered to hosting providers |
| IP changes | Rotating: a new IP on every request. Sticky: the same IP for 1, 3, 10 or 30 minutes | The same assigned IP for the whole term | The same assigned IP for the whole term |
| Billing | Fixed GB traffic packages, each valid for 30 days | Per IP, for a 30 or 90 day term | Per IP, for a 30 or 90 day term |
| Location | Country, and a state or region where available | Chosen location per line (Native ISP or ISP) | Chosen location; one order can span several |
| Typical uses | Public web data, price and localization checks, short logged-in tasks on sticky sessions | Long-lived accounts, one IP per browser profile | Monitoring, testing, API work and high-volume requests to sites that accept datacenter IPs |
| Trade-off | Heavy pages use more traffic; rotation can break a signed-in session | Priced per address, so many IPs add up; renewal is manual | Easy for sites to recognise as datacenter; renewal is manual |
Rotating Residential: many addresses, billed by traffic
With Rotating Residential you do not rent an address. You buy a fixed traffic package in GB, and every request goes out through an exit on a residential network. Each package is valid for 30 days, and any traffic left over expires on the date shown in your dashboard. You cannot type in a custom amount; you pick one of the plans on the pricing page.
When you generate a connection you choose a country and, in many countries, a state or region. City, ASN, carrier and ZIP targeting are not offered. Location follows IP geolocation, and lookup services do not always agree, so a state check on one site can differ slightly from another.
You also choose the session type. Rotating gives every request a new IP, which suits scraping and price checks where no single address should carry too many requests. Sticky keeps the same IP for 1, 3, 10 or 30 minutes, long enough to sign in and finish a short task. If you need the same address tomorrow, sticky sessions will not give it to you; that is what Static ISP is for.
Because you pay by the GB, the cost follows the size of what you load. A product page full of images and scripts uses far more traffic than a small JSON response. If your scraper downloads images or full pages it does not need, you pay for that data. Blocking images and fetching only the parts you parse makes a package last longer.
Connections use HTTP or SOCKS5 with one managed username and password, issued when your first package is delivered. IP allowlisting is not offered. Generating 100 connection lines gives you 100 configurations, which is different from 100 unique IPs.
Static ISP: one address that stays yours
A Static ISP proxy is a fixed address registered to an internet service provider. It is assigned to you for the term you pick, 30 or 90 days, and billing is per IP and term, so traffic is not metered. You choose a location, a term and how many addresses you want, and each address arrives with its own host, port, username and password. HTTP and SOCKS5 are both supported.
This is the type to use when a site should see the same visitor every day. In an antidetect browser such as AdsPower, the usual setup is one Static ISP address per profile, kept for as long as that account exists. Avoid sharing one address across many profiles, since every account on it then appears to come from the same connection.
IPMusk sells Static ISP in two lines, Native ISP and ISP. Both are fixed ISP-registered addresses with the same terms, delivery states and connection method. They come from two separate address pools, each with its own location list and prices, so a country may appear in one line, the other, or both. Pick the line that lists your location at the price you want. If a target site treats addresses from one line differently, the other line is your alternative.
Renewal is manual. You start each renewal yourself, choose an available extension term and pay for it as a separate order. Renew before the expiry date if you want to keep the same address, because it may not be available once the term has ended. Automatic renewal, credential changes and IP replacement are not offered.
Datacenter: lower priced, and easy to recognise
Datacenter proxies are fixed addresses registered to hosting providers. At IPMusk they are the lowest-priced static option. Like Static ISP, they are billed per IP for a 30 or 90 day term with no traffic metering, and one order can spread its IPs across several locations. Each address has its own credentials, and HTTP and SOCKS5 share the same port.
The trade-off comes from the registration. IP databases usually list these ranges as datacenter addresses, and many sites check exactly that. A platform that blocks or flags datacenter ranges will treat these addresses the same way. The proxy is working as intended in that case. The site has simply decided it does not want traffic from hosting networks.
That still leaves plenty of work where datacenter IPs do well: price monitoring on sites that accept them, testing your own services, API calls and high-volume requests where the destination does not care where traffic comes from. For a social or store account that a platform watches closely, an ISP address is the safer choice.
Renewal is manual here too. The address, port and credentials stay the same when you renew, but an address that has expired and been released cannot be recovered by renewing later.
Which one to buy
Start from what the target site checks and how long you need the same address.
- Pick Static ISP if you run long-lived accounts in an antidetect browser (stores, ad accounts, social pages) and want one fixed IP per profile that looks the same every day.
- Pick sticky Rotating Residential if you need a residential address for a short signed-in task and can finish within 30 minutes.
- Pick rotating Rotating Residential if you collect public data, check prices or verify localized pages across many requests, and the pages are light enough that traffic billing stays reasonable.
- Pick Datacenter if the destination accepts datacenter traffic and you want a fixed address at the lowest price, for monitoring, testing or API work.
Check an IP before you scale up
Buy a small quantity first and test it against the sites you actually use. A successful test request only shows that the proxy connects; a target site can still block or challenge an address.
The free IP quality check scores the connection it sees from 0 to 100 and lists each deduction, including whether the network is a datacenter, mobile or ISP network. Run it inside the browser profile that uses the proxy. If you have several proxies to test, the proxy checker takes up to 20 at a time and shows whether each exit is a datacenter or an ISP network.
