Зачем нужна ротация IP адресов

Reasons to Rotate IP Addresses

Every device connected to the Internet has its unique IP address. If a large number of requests start coming from one IP to a server (site), the owner or operator of the server might consider this suspicious for various reasons and may block this IP either permanently or temporarily:

• Activity of bots or other automated services, which either collect information from the site on a large scale or attempt to disrupt its normal functioning;
• Risk of a DDoS attack on the site, which could cause it to go down;
• The site may be intended specifically for human users, not robots, and multiple automated requests indicate a violation of this policy;
• Security issues, such as attempts to bypass CAPTCHA, registration, or data manipulation;
• Attempts to bypass daily usage limits or other abuse of limited content.
  Therefore, if a user of a specific IP does not want to be blocked permanently or temporarily, IP rotation is most often used, where one IP address is replaced with another.

When is it truly necessary to change the IP address

What is considered "suspicious" activity by websites might actually be normal business activity. Many modern professions involve using the Internet to gather a large volume of data as part of a big task or repetitive similar tasks:

1. Forming complex queries to chatbots, which require in-depth analysis (within a single request, a chatbot may send requests to hundreds or thousands of online resources within a few minutes).
2. Using a single outbound IP from a corporate network where hundreds or thousands of employees work, each performing different tasks and creating independent requests.
3. Operation of automated internal systems that collect data (data synchronization, update checks, aggregation).
4. Gathering large amounts of data, requiring many identical requests to the same database where this data is stored.
5. Working with cloud infrastructure, where access to different applications may be made from a single ingress IP.
6. Analytics and monitoring tools operating online.
7. Data aggregation services.

If the owner of a specific server receiving such requests has not signed an agreement on data usage, then suspicious activity will be blocked. Therefore, IP addresses need to be changed.

Methods of changing IP addresses

In the matter of changing IP addresses, rotational proxies come into play. You can order their setup and operation through our company at the best prices. Rotating proxies are services that change the address according to a predefined logic. Currently, four rotation methods are used in practice:

1. With preset intervals. This means that after a specific period (e.g., 1 hour), a new IP address is automatically assigned to the user, regardless of whether it is needed at that moment or not.
2. Random rotation. Each new user or new session is assigned a random IP. In this case, the user cannot influence which IP they will get.
3. Batch rotation. The IP changes every few sessions, such as every 5, 10, or another specified number.
4. Manual change. The user changes their IP themselves when necessary. They may be given the option to choose an address or be assigned a random new IP.

Practical approaches to rotation

To set up residential proxies with rotation for IP address change, you can:

• Install a browser extension or program on your computer/laptop/phone and configure IP change options according to your needs;
• Write code to change IP manually, suitable only for advanced users who can write the relevant code (or are good at doing VAB coding);
• Use professional offers from companies that have solutions for IP rotation. For example, you can purchase proxy rotation services through a paid subscription to such a service.
