This article mainly introduces how to choose a high-quality agent IP, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

1. The agent scanned by the program. Scan the IP segment and port for temporary proxies found by the program.

For example, Baidu search HTTP agent, write daily updates, domestic Gaomi free what is like this, buy it is very cheap.

Basically the same, there is nothing good, several platforms provide agents with at least 30% repetition rate.

This kind of agent, the validity period is not high, even if the batch verification in the use process will still abolish some, can cope with inefficient collection, brush a single visit, but forget the others.

2. ADSL dial-up server

ADSL dialing, disconnected reconnect IP, Taobao has to sell, limited area dialing, national dialing. Relatively stable, at least much better than scanning, but switching IP takes a long time, from a few seconds to a minute.

Therefore, if the collection is accessed once and cut off one IP at a time, the efficiency will be very slow and can only wait until the current IP is deleted by the other party's ban and dial for a new IP.

Last year, brushing Baidu drop-down, do Baidu clicker agent switch once used ADSL dialing, more stable, some effect, of course, also used the above swept agent, too bad, can not be used. However, because IP switching requires disconnection and reconnection, concurrent tasks are not easy, so large-scale scale costs.

ADSL dialing can deal with low efficiency requirements such as collection, access, click, and so on.

3. Third-party access

For example, to find the target web page through third-party access channels such as Google web page translation, youdao web page translation, http proxy browser and so on.

The speed is slow, and there is a lot of interference when collecting and capturing the target content.

4. Self-built agent

Buy a server and use squid+stunnel to build a HTTP high concealment proxy server. Tinyproxy can also be used. Squit is used to implement http proxy, and stunnel builds a tunnel on the basis of proxy to realize encryption.

If you feel that the number of ip is small, buy a few more servers and configure squid~~ in turn.

Because they are self-built agents, they are all exclusive, and the real IP is quite stable. Collect, snap up, brush ticket, brush click, brush host popularity and so on, only have the money to get on the machine.

Last year, I received a list of crawlers and caught a foreign stock website with a total of 10 million pages. The anti-crawler is disgusting. I have no choice but to buy 20 low-end machines as HTTP proxy servers, 5000 yuan per month.

5. Self-built agent service provider.

If you don't bother to do the above methods, it doesn't matter. Find a business that does similar services and open an api port. For example, the Sun http
