Proxy Server: Proxy Server Construction and Management Tips

What the hell is a proxy server anyway?

To put it bluntly, a proxy server helps you toStaging areas for transmitting network requests. For example, if you want to visit a website, the direct connection is easy to be found in the real identity, this time to let the proxy server to help you pass the message, the other side can only see the address of the proxy. It's like ordering a takeaway don't want to expose their own address, fill in a collection point address a reason.

There are two main types of proxy IPs on the market now:Residential IP(real user network) andData Center IP(Server room server). Like doing data collection with residential IP is not easy to be blocked, batch operation choose data center more cost-effective. Here we must mention the ipipgoTK LineThe delay can be compressed to less than 100ms, specially optimized for the Southeast Asia region.

Build your own proxy server? Hands on.

Let's start with the simplestSquid construction methodThe software is suitable for Linux systems. Modify the configuration file after installing the software:

http_port 3128
visible_hostname myproxy
acl localnet src 192.168.1.0/24
http_access allow localnet

This code means to open port 3128 to allow devices on the intranet 192.168.1. But there's a pitfall with self-built proxies--IP easily blocked. Last month there is a cross-border e-commerce friends, they got 20 servers to rotate IP, the results of three days to be recognized by the ban, and then changed the ipipgo'sStatic Home PackageOnly then did it stabilize.

How do you choose a ready-made proxy service without stepping on the toes?

Remember three key points when choosing an agency service:
1. IP purityDon't believe those who claim to have millions of IPs, many of them are reused dirty IPs!
2. Protocol Support: at least Socks5 support, https protocol is the basis of the
3. responsiveness: Less than 200ms in Southeast Asia, not more than 500ms in Europe and the United States.

Take ipipgo, theirDynamic Residential Enterprise EditionSet of real-world data:
- First connection time: 1.2 seconds
- Download speed: 3.8MB/s
- Average daily IP survival rate: 89%
Than the self-built agent to save too much heartache, the key is the price is only 9 yuan more than 1GB flow, do crawl brother with this cost can be reduced by 60%.

Don't step on these potholes!

Case one:A game studio used free proxies to brush up on quests, resulting in accounts being blocked en masse. It was later discovered that the IP pool was mixed with flagged fraudulent IPs.
A guide to avoiding the pit:Use free proxies with caution! It is recommended to choose ipipgo withQuality Inspection APIservice provider, calling the interface will sift through the available IPs.

Case two:A team doing an overseas survey had their data invalidated due to the IP country jumping around.
Solution:Switch to ipipgo.cross-border rail linethat can target specific city-level egress IPs, in conjunction with their provision of theclient software, switching countries at the touch of a button is faster than flipping a book.

QA time: questions you might care about

Q: What should I do if the proxy IP suddenly fails to connect?
A: First check if the authentication information is correct, if you are using ipipgo's service, their client has theIntelligent switching functionIf you do, tap the Reconnect button to automatically change to a new IP.

Q: How do I manage multiple agents at the same time?
A: It is recommended to use the ProxyChain tool for load balancing, or directly use the ipipgo provided by theAPI interface, code example:

import requests

proxy = {"http": "http://user:pass@gateway.ipipgo.com:9021"}
response = requests.get("destination URL", proxies=proxy)

Finally, a cold one: nowadays many websites use theBrowser FingerprintingIf you want to change your IP address, it's not enough to just change your IP address, remember to change your User-Agent and time zone settings. If you need in-depth customization, you can look for ipipgo customer service.1v1 programThey have dealt with all kinds of oddball demands, and have even taken on cases that simulate the network environment in rural Africa.
