The word proxy is used to describe a communication interface in a network. A proxy serves as a mediator: it receives requests, forwards them via its own address, and thus establishes a connection.

A private proxy is an exclusive proxy server that can only be assigned to one owner. It is used to hide one' s own proxy IP and thus create a certain degree of anonymity.

If a proxy of this kind is booked with a provider, it is exclusively available to this customer for the booking period and can only be assigned to other customers after the end of the contract. This means that every private proxy is available for a period of at least one month with the customer and only the customer can use it.

You can explore various options and purchase a private proxy that suits your specific needs by visiting the Private Proxies Pricing Page. To ensure complete control and privacy, opting for a private proxy is a solid choice.
Difference between private and public proxies
Unlike a public proxy server, dedicated or private proxies are protected and can only be used with a user name and password.

Furthermore, with a dedicated proxy server, the IP address always remains the same and cannot be changed. One advantage of dedicated proxies is their very high connection speed and permanent availability. Due to this unlimited availability of a private proxy server, the connection is always stable.

Private proxies are usually less constrained by the proxy provider than shared proxies. This means that the customer who uses them has the possibility to open more simultaneous connections to certain websites.

Since a private proxy returns to the proxy pool after being used by a customer with an expired contract, and a new customer is assigned to it, it can also be negatively charged. For example, if the previous customer visited certain sensitive sites, the proxy address may have been banned.

So before purchase (if there is a free trial) or immediately after payment during the warranty period (usually 1-2 days) you should make sure that the IP data is not blocked on the target site. In such cases, the provider usually offers a replacement or refund.

Basically, all proxy providers must pledge not to disclose the data to third parties, but the data and activities are registered with the service provider and can thus be attributed to a customer. So if you are mainly looking for good speed and have nothing to hide, you should choose a private proxy, because their performance is convincing.

Even those who want to access content that is not displayed by their own conventional IP address can circumvent the problem by using a private proxy. Streaming services, for example, do not offer all content in every country and by using a private proxy, the customer can change their location and thus have access to the content.
Private Ports
The equivalent of private proxies for mobile proxy services are so-called private ports. However, these private ports may not only be used in mobile device settings, but generally in any device such as laptop, phone, VPS, etc.

This means that if the customer is looking for a way to access the Internet via a mobile IP address or to use his bot so that the target site perceives this visitor as if he was using a smartphone, this person must use the services of a mobile proxy provider.

Mobile proxy services are divided into private and shared IPs. If the customer only needs (private) proxies dedicated to them, a private port is assigned to them. This is a specific IP address (gateway IP) and a non-standard port. The IP addresses that the customer receives at the exit (exit IPs) are only available for this customer. How this works is explained in the article "What are mobile proxies?”
