Mobile is the most “trusted” format: the address belongs to a mobile operator, and to the site, it appears as a regular smartphone user. In return, it has the highest price and a non-permanent address. Below is how it differs from each format individually.

​

IPv4 is a static data center address: it is assigned to you and does not change, is inexpensive, and works quickly. Mobile is more expensive, the address changes, but sites treat it very differently. IPv4 is used for large-scale tasks, Mobile — where a regular address does not pass.

​

ISP is also a highly trusted address, but static and issued by an internet provider, meaning it looks like home internet. Mobile looks like mobile and allows changing IP. If a constant address is needed — ISP, if a change is needed — Mobile.

​

IPv6 is about quantity and price: there are many addresses, and they are the cheapest, but they belong to a data center and only work with sites that support this standard. Mobile is the opposite: there are few addresses, they are expensive, but they pass almost everywhere.

​

Both formats are dynamic and both have high trust, but they are structured differently. Residential is a rotation from a shared pool of more than 20 million real user addresses, with payment for traffic and coverage across countries and cities. In Mobile, you get a specific operator and region, pay for the proxy, not for traffic, and manage the address change yourself — by link or timer.

Mobile is needed when trust from sites and the ability to change the address are most important. Need a constant address — IPv4 or ISP. Need volume cheaper — IPv6. Need coverage in many locations with payment for traffic — Residential.
