All our formats are divided into two groups based on one criterion — whether your IP address changes during operation. This also affects how the format is paid for and what tasks it is suitable for.
Static address
A static address is assigned to you for the entire rental period: it does not change by itself and is not available to other clients. You pay for the address itself and the term, and the traffic volume does not affect the cost.
Such addresses are used where consistency is important: working with services that remember where you connect from, long sessions, access to resources with address restrictions, and any tasks where changing the IP in the middle of work breaks everything.
We have three static formats: IPv4, ISP, and IPv6. They differ in the origin of the address and price, but they all have one thing in common — the address is constant.
Dynamic address
A dynamic address changes: on schedule, at your command, or for each request. You connect to one entry point, and the system itself substitutes the next address from the pool.
Such addresses are used when many requests are made from one IP and the site starts to limit them, when you need to view a resource from different locations, or when it is important that requests do not look like a stream from one address.
We have two dynamic formats: Mobile — a mobile operator's address with a change by link or timer, and Residential — rotation from a common pool of real users' addresses with payment for traffic. The modes of address change are shown in the article Address rotation.
How to choose
If the task requires you to be recognized by the same address, choose a static format. If, on the contrary, the work is limited by the number of requests from the address or coverage in different locations is needed, choose a dynamic format.
Sometimes it is more convenient to combine: a static address for constant work and dynamic ones for mass tasks. Orders of different formats live in one account and do not interfere with each other.
