Registered residential, hosted professionally
A lookup on the address returns a consumer ISP, which is what most detection actually checks. The connection behind it is a data centre link, so throughput and uptime are what you would expect from hosting rather than from somebody home broadband.
Stability is the real advantage
Residential exits depend on a real connection that can go away. ISP addresses stay up, which matters enormously for long sessions, anything that must hold one identity for hours rather than minutes.
Priced between the two
More than datacenter, less than residential. For sustained work that needs to look legitimate, it is frequently the best value of the three.
What to buy
ISP when you need one stable identity held for a long time and datacenter gets blocked. Sticky sessions, and keep each identity on its own exit.
Common questions
What is an ISP proxy?
An address that belongs to a consumer internet provider but lives in a datacenter. It carries the ownership of a residential address and the speed and stability of a server, which is an unusual combination and the reason the class exists at all.
When is ISP better than residential?
When you need an address that both looks like a household and does not move. Residential addresses are borrowed from real connections and rotate as those connections come and go. An ISP address stays yours for the term, so anything that has to be allowlisted, kept consistent, or held across days is a much better fit here.
Can I get a static IP?
Yes, that is the point of the class. You can pin to static addresses, and one line is issued per address. Worth knowing that pinning and rotating session mode are mutually exclusive, so choose which of the two the work actually needs rather than expecting both.
