SOCKS5 Proxy Definition: SOCKS5 Protocol Technical Details

What exactly is a Sock 5 agent?

In human terms.network brokerSOCKS5 is a courier that forwards network requests for you. The biggest difference with the ordinary HTTP proxy is like the difference between a tricycle and a truck, SOCKS5 can carry various types of "goods" (support for all protocols of TCP/UDP), especially suitable for the need to stabilize the transmission of the scene.

For example, if a game studio wants to register accounts in bulk, using a SOCKS5 proxy will allow each account to go to a different region's IP, so as to avoid abnormalities detected by the platform. At this time, if you use ordinary HTTP proxy, it is like using the same key to open all the locks, minutes by the wind control system caught.

Core mechanisms that only tech geeks can understand

The whole process is a three-step process:
1. handshake phase: The client sends a "code" (0x05 0x01 0x00) to tell the server not to do all that fancy authentication stuff.
2. establish a connection: Package the address to be accessed (e.g. Taobao server IP) and send it in a specific format
3. transmitted data: this is where the proxy becomes a transparent pipe

 Quickly test if a proxy is available with Python
import socket
proxy = ("proxy IP", port number)
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect(proxy)
sock.send(b "x05x01x00") Handshake packet

The three lifebloods of choosing an agency service

Hands on with ipipgo!

Find it in the ipipgo backend"One-click configuration generation"function, select the Socks5 protocol type. Here's a tip:

Guidelines on demining of common problems

Q: What should I do if the agent keeps dropping out?
A: eighty percent is using a shared IP pool, change ipipgo's dedicated line to try. Their TK line has an automatic reconnection mechanism, and the drop rate can be reduced to less than 0.3%.

Q：Configuring the proxy in the code always reports an error?
A: 90% probability is that the agreement header is not written correctly, check if the authentication field is missing. Use the code generator provided by ipipgo to automatically generate configuration templates for different languages.

Q: Traffic running out especially fast?
A: It may have gone UDP traffic, which is turned on in the backgroundFlow CompressionFeature. The real test can cut down the traffic consumption of video-based services by 40%

Why older drivers choose ipipgo

this onecross-border rail lineIndeed have two brushes, the last time to help customers do cross-border data synchronization, with ordinary agents to 2 hours, cut to their dedicated line after 20 minutes to get done. The most important thing is the supportper-minute billing, short quests can save a lot of silver.

Highlighting theirSERP APIService, SEO friends should understand. The traditional program to maintain their own proxy pool + parsing web pages, and now directly call the interface to get structured data, but also with anti-anti-crawl mechanism, saving at least 3 programmer's salary.

The last nagging sentence: do not believe that those 9 yuan 9 monthly pheasant service, serious business still have to find ipipgo such a formal operator resources. Now new users can get 20% off the first single, old customers recommend friends can earn commission, specific to the official website to see it.
