What proxy ip is generally used by crawlers?Residential, server room, data center comparison

Crawler choosing proxy IPs is like choosing an invisibility cloak

The old iron engaged in crawling understand that there is no good proxy IP is like running naked on the Internet. Proxy IPs on the market are mainly divided intoResidential IP,Server Room IP,Data Center IPThere are three categories, which one to choose all depends on the business scenario. Let's take the rental as an analogy: residential IP is a real resident in a residential district, server room IP is like a monthly room in a fast hotel, and data center IP is a large bunk in a youth hostel.

A real-world comparison of three proxy IPs

Let's start with a whole comparison table for the guys:

To give a real case: last year, there is a price comparison website friends, with the IP room to climb an e-commerce platform, the first three days of the data to pick up the fly, the results of the fourth day of the direct blocked more than 2,000 IP. later replaced with aDynamic residential IP for ipipgo, in conjunction with their rotation strategy, the survival rate pulls right above 901 TP3T.

Golden matching program for different scenes

1. Countering Anti-Crawlers: must be on the residential IP, especially like a treasure, a big platform such as East, their anti-climbing system can identify the IP segment of the server room. ipipgo's dynamic residential IP supportRotation by sessionThe new IP will be changed for each request, which has been tested to be effective in bypassing the frequency detection.

import requests
proxies = {
    'http': 'http://username:password@gateway.ipipgo.com:端口',
    'https': 'http://username:password@gateway.ipipgo.com:端口'
}
response = requests.get('destination URL', proxies=proxies, timeout=10)

2. Long-term stable acquisition: It is more cost-effective to choose a static residential IP, for example, to continuously monitor price fluctuations in a certain region. ipipgo's static IP packages supportCity-level positioningIt also maintains session persistence, which is particularly suitable for scenarios where login state is required.

3. Massive amount of public data: Use a data center IP to save money, but be prepared - collecting 100,000 pieces of data can cost thousands of IPs. this scenario is recommended to pair with theipipgo's Dynamic Enterprise Package, their IP pool is large enough that blocking and automatically replacing it with a new one doesn't delay things.

Anti-Blocking Tips for Older Drivers

Name a few potholes that are easy to step into:
1. Don't think you can do whatever you want with a residential IP, a certain red book's anti-crawl will detect theMouse movement track
2. The collection frequency must not be as machine-like, it is recommended to use thestochastic delay+Working time simulation
3. Don't be a hard ass when it comes to CAPTCHA, ipipgo has a solution for that.Automatic CAPTCHA Bypassfunctionality

QA session

Q: How to check if the proxy IP is valid?
A: Recommended for ipipgoReal-Time Detection InterfaceThey can check anonymity levels and response rates, and they have an automatic elimination mechanism in the background.

Q: What should I do if my proxy IP is slow?
A: 80% of them are using cross-continental nodes, ipipgo supportCity-level positioningIf you choose an export IP in the same city as the target server, the latency can be reduced by more than 70%.

Q: How do I choose a package with a limited budget?
A: PrioritizationDynamic residential (standard)packages that support per-traffic billing. ipipgo has a hidden trick - set theIP survival time = acquisition interval, which saves 30% in traffic charges.

Finally, a piece of advice: do not be greedy for cheap to buy those who claim unlimited flow of pheasant agent, our team has suffered losses - pick to the key data when the IP pool suddenly dropped, almost delayed the project acceptance. Now the whole line of business with ipipgo, especially theirStatic Residential AgentsThe company's customer service is also able to give customized collection solutions, which is much more worrying than the self-built agent pool.
