Proxy servers have what: mainstream proxy protocol types and applicable scenarios comparison

What can a proxy server really do? Let's start with a real-life scenario

Folks may have heard of proxy servers this stuff, but what problems can be solved with it? To give a real example: do e-commerce friends to batch check the price of competing products, using their own network is easy to be blocked IP; engaged in crawling brother continuous access to the site was 403 blocking the way; do advertising to test the effect of different regions landing page ... these scenes!Change the IP address and you'll break the game.The way to do this is to choose a different type of agency agreement for different businesses. There are a lot of doors here, and different businesses have to choose different types of agency agreements, just like stir-frying vegetables, depending on the heat.

Comparison table of the Big Four protocols (straight to the dry end)

Protocol Selection Practical Manual (copy your homework)

HTTP/HTTPS ProxyThe most suitable for doing web automation, like using Python to write crawler scripts, requests library directly hanging proxy parameters on it:

import requests
proxies = {'http': 'http://user:pass@ipipgo-proxy:port'}
resp = requests.get('destination URL', proxies=proxies)

But be careful.Don't exceed the package limit for concurrencyipipgo's Dynamic Residential Package allows 10 concurrency per IP by default, and will automatically switch to a new IP if it exceeds the limit.

Socks5 protocolIdeal for scenarios where large files need to be transferred, such as when using curl to download overseas resources:

curl -x socks5://ipipgo-user:password@gateway.ipipgo.net:1080 https://资源地址

The actual test with their TK line can speed up 40% than the ordinary agent, especially in Southeast Asia access delay can be pressed to 200ms or less.

A Guide to Avoiding the Pit (Blood and Tears)

1. Don't use free proxies for cheap, last year a brother climbed the data and used a wild IP library, the result was reverse implanted mining scripts.
2. residential proxy ≠ home broadband, ipipgo's static residential IPs are allLocal real home network outletsI can pass the 99% counter-crawl verification.
3. Don't panic when your IP suddenly fails, their API supports automatic replacement, remember to set the failure retry mechanism.

QA Time (Frequently Asked Questions Dislike Face Answers)

Q: Do I choose a dynamic or static package?
A: Dynamic for high-frequency IP switching (e.g. batch registration), static for fixed IP scenarios (e.g. long-term number maintenance), and ipipgo's Enterprise Edition dynamic package supports IP switching per second.

Q: The price looks more expensive than others?
A: their IP purity is guaranteed, measured 100,000 requests blocking rate of less than 3%, 5 times lower than the market average, equivalent to saving 30% invalid traffic fees!

Q: How do I test the quality of the proxies?
A: Recommended to use curl to measure the response time + browser to check the IP belongs to the ipipgo client comes withDelay Diagnostic ToolThe packet loss rate for each node can be seen in real time.

Tell the truth (the boss won't let you write it)

The agency services business is a deep one, and some vendors playIP Pool RecyclingThe 100 IP outwardly declared 100,000 inventory. ipipgo dare to do exclusive static IP is because there is a self-built machine room, unlike some second-hand traffickers selling data. In addition, their home cross-border line is really fragrant, do tiktok old iron know understand, here will not expand said (for fear of peer reporting).
