What do you need to know in advance before purchasing a proxy IP?

The rapid development of the Internet has made the use of IP proxies more and more widespread. However, before using IP proxies, in order to avoid unnecessary mistakes and improve work efficiency, we should understand some basic concepts. Therefore, before purchasing a proxy IP, you need to consider the following three issues: proxy agreement, licensing model, and survival time.

1. Agency Agreement

There are three common proxy protocols – http protocol, https protocol and socks protocol. HTTP proxy is the most common type of proxy, mainly used for proxy browsers to access web pages, usually using ports 80, 8080, 3128, etc. The https protocol supports up to 128-bit encryption strength and can be used as a proxy to access encrypted websites. Socks proxy is an all-purpose proxy, similar to a patch panel for jumpers, which can simply connect the system at one end to the other end. It supports multiple protocol requests including HTTP, FTP requests, and other types. Socks proxies are divided into two types: Socks 4 and Socks 5.

2. Licensing model.

High-quality proxy IPs usually require authorization before use. The two most common methods are terminal IP authorization and username and password authorization. Under IP authorization, the public network IP is used to bind the proxy IP, which can be bound to the backend API interface for automatic calls; while username and password authorization requires account verification. Note that these two authorization methods cannot be used together, and you need to decide which method to choose before use.

3. Survival time.

All proxy IPs have a lifespan and will become invalid once it expires. Even static proxy IPs have a certain lifespan, but it is longer. Depending on the needs of different companies, there may be different requirements for the lifespan of proxy IPs. If the business needs the lifespan of the proxy IP to be very unstable, such as 10 minutes, 1 hour, etc., then you can use a separate IP pool.

So, how do you choose which proxy IP to buy?

First of all, high concealment is the basic requirement for choosing a proxy IP.

Secondly, a large-capacity IP pool is very important for data collection or incremental users, because they need to use millions of proxy IPs every day. If the supplier's IP pool is insufficient, it will not be able to meet the work needs, and may even be banned for repeated use of the same IP.

Finally, stability, including IP stability, server stability and after-sales service. IP instability may cause many problems later, which must be considered.

When choosing an overseas IP proxy supplier, Kookeey is very worthy of consideration. All Kookeey IPs are screened at the business level. Relying on the accumulation of business big data and IP library retention algorithms, it can provide you with quality-screened IPs in specified application scenarios, ensuring 100% purity and exclusivity.
