Proxying: How to Choose and Buy a Proxy

Almost every modern application interacts with the external environment. It accesses APIs, retrieves data from remote storage, and exchanges requests with computing systems, authentication services, and distributed nodes.

Some applications require an application to access the network from different IP addresses. This is necessary when the receiving end takes into account the connection source: it imposes request limits, applies regional restrictions, divides traffic according to rules, or blocks some connections.

When the exit address and network parameters are defined in the launch environment, changing the IP address or traffic route requires reconfiguring that environment. A proxy solves this problem much more easily by isolating the connection to a separate node with its own parameters. The source address, protocol, access rules, and connection behavior are defined on the remote proxy server, independent of the application, its environment, and its actual location.

This technology is used where the separation of network roles is required. The same software performs the same actions, but accesses the internet from different addresses and uses different protocols. All this simplifies scaling, testing, and automation, and allows you to isolate traffic and reproduce specified conditions without changing the application logic.

Ready-made proxies instead of custom configuration

Proxies are no longer a rare technology. Running your own proxy servers, configuring routing, and monitoring addresses and their status only makes sense in exceptional situations. For most tasks, this approach is redundant and offers no practical benefits.

In practice, ready-made proxies from specialized providers are most often used. These services provide pre-configured proxy servers in the required quantity, with preset parameters, protocols, and geographic locations. The user doesn't need to understand network infrastructure—simply select the appropriate type, purchase a proxy, and obtain connection information.

After this, it's time to choose a provider. The provider determines not only the behavior of the addresses themselves but also how issues will be handled during operation, including replacements, extensions, non-standard situations, and support requests.

How to purchase a proxy using Proxy-Solutions as an example

Before purchasing, it's important to understand what proxy is needed for the task. The type determines the source of the IP addresses and their usage.

Proxy-Solutions offers the following options:

• Personal — private, assigned to a single user;
• Package — supplied and renewed only as part of packages;
• Prime (ISP) — from internet service providers, appearing as regular user sessions;
• City — tied to a specific city;
• Mobile — from mobile operators with dynamic rotation;
• Mobile Plus — from mobile operators with choice of city and operator;
• Multiprotocol — access via Shadowsocks, SOCKS5 + TLS, Trojan + TLS, and VLESS + TLS;
• UDP — transmitting UDP traffic.

Next, you can select and place your order.

Creating an order and receiving data

The purchasing process at Proxy-Solutions consists of two steps: configuration and payment. For example, the "Mobile Proxies Plus" service requires configuration of several parameters.

First, you specify the location. Select the country, then the city. Separately, you specify the service provider whose network will be used to provide the addresses. Next, you select the rental period and the number of channels. A channel corresponds to one proxy, so this number determines how many simultaneous connections will be available within the order. The "Multiport" option, activated, allows you to change the city and service provider within the selected country after the purchase.

Next, you enter your email address and select the payment method. The system calculates the amount to be paid and creates the order.

After payment, proxies immediately appear in your personal account, in the "My Proxies" section. Active orders are displayed there, along with their location, number of proxies, and rental end date. The following actions are available for each order:

• Download data;
• Extend the order period;
• Enable or disable auto-renewal;
• Open authorization settings.

Connection data is provided ready-to-use. It can be accessed in your personal account either as a list to copy or as a file.

When downloading, you can choose the file format and proxy recording format. Text, table, and JSON formats are supported, as well as several list formats with different address, port, and authorization data ordering. If necessary, you can define a custom list format for a specific application or script.

Authorization: login and password or IP binding

The access method is configured in the "Authorization" section for a specific order. There are two options.

The first option is a username and password. These can be entered manually or generated automatically, after which the changes are applied.

The second option is binding to the client's IP address. In this mode, the connection is established without a username and password if the request comes from an authorized IP. You can specify up to three IP addresses in your account.

Additionally

In addition to the proxies themselves, Proxy-Solutions offers infrastructure for managing them. Management is possible not only through your personal account but also programmatically, using the REST API. The API can be used to retrieve data on active proxies, renew services, replace addresses, and integrate them into automated scripts and services.

Chatbots have been launched in Telegram and Viber for viewing information and performing basic operations. There's also a dedicated browser extension linked to your Proxy-Solutions account. It retrieves proxies from active orders in your personal account and automatically inserts them into your browser settings.
