With the rapid development of the Internet, whether it is not Internet enterprises have started a large data collection and analysis, the establishment of their own large database, resulting in the creation of countless data acquisition companies, which is what we call the network crawler, network spider, web crawler in the data collection need to use a large number of proxy IP, So what is the proxy IP to have a cost-effective?

Perhaps someone will blurt out, of course, free proxy IP is the most cost-effective AH. But is that really the case? Let's take a look at the analysis.

At present, the agent IP has free, there are paid IP agents, but when it comes to cost-effective, many friends may take it for granted that the free proxy IP should be the most cost-effective, after all, no money. But the friends of this point of view did not take into account the cost of time, next, the small part of the free proxy IP and pay proxy IP in the cost of the difference, pay proxy IP is divided into software provided, API Port extraction.

The first is the free proxy IP, although free of charge on the surface, but it is undeniable that the current free proxy IP availability rate is appalling, almost equal to not available, access to 100 IP, the results can be used 5 are not, greatly increased the time cost, this type of IP is only suitable for enthusiasts, Beginner practiced hand use.

Followed by a paid proxy IP, paid proxy IP has many providers, some also provide software, only one key can be replaced by IP, greatly reducing the use of the threshold, won the love of individual enthusiasts, but this kind of proxy IP is for individual users, because the equivalent of retail, so the price is high, IP availability ratio is higher than free, approximately between 40-70%, and the IP pool is not large, mostly within 10W IP volume, there may be a daily extraction limit, of course, because each provider's pricing strategy is different, so there may be some discrepancies.

Finally, it is for the enterprise customer's reptile proxy IP, such as the flying ant Agent . IP quality requirements, because a day may be extracted to millions IP, so the IP pool requirements are high, is generally tens IP pool, this type of provider cost-effective, the equivalent of wholesale, cheap pricing, high IP quality, nodes throughout the country, because it is a self-built server, high degree of stability, The IP that can be extracted every day reaches millions of.
