Shared Proxy IP | Cost-effective IP pooling solution, preferred for small and medium-sized crawler projects

First, why do small and medium-sized crawlers use shared proxy IPs?

Friends who have done data crawling have encountered such embarrassment: just run two days of crawler scripts suddenly failed, the target site began to frequently block IP.shared proxy IP poolIt's like timely rain - acquiring massive IP resources at a lower cost, allowing multiple users to share the cost of usage. Especially for crawler projects that need to run for a long period of time, the IP rotation mechanism can reduce the access frequency of individual IPs while maintaining the continuity of data collection.

Second, the three major screening criteria for cost-effective IP pools

Proxy IP services on the market are uneven, and choosing the wrong service provider may lead to crawler paralysis. It is recommended to focus on these three dimensions:

1. Real IP coverage:Residential IPs are more difficult to recognize than server room IPs. Residential IPs like ipipgo's come from real home networks covering 240+ countries and regions around the world and are much more camouflageable

2. Protocol adaptation capabilities:Support HTTP/HTTPS/SOCKS5 all protocols in order to cope with different website environments, this point ipipgo's dynamic IP can automatically switch the protocol type

3. Connection success rate:The connection success rate of the measured dynamic IP pool should be >95%, otherwise frequent failure retries will slow down the collection efficiency

Three, three steps to build a stable IP pool of practical skills

A python crawler as an example, quickly deployed through the API interface of ipipgo:

Step 1: Set up an IP rotation policy--Dynamically adjust the switching frequency according to the anti-climbing mechanism of the target website. Websites with high access frequency are recommended to change a batch of IPs every 5 minutes

Step 2: Anomalous IPs are automatically rejected--When an IP fails for 3 consecutive requests, it is immediately removed from the current IP pool and replenished with new IPs.

Step 3: Traffic Load Balancing-Evenly distribute requests to IPs in different geographic locations to avoid alerts caused by centralized access to IPs in a certain region.

IV. Common Misconceptions about Maintaining IP Pools

Many users tend to make two mistakes in the process:

1. Blindly pursuing the number of IP, ignoring quality control. It is recommended to start with ipipgo'sFree TrialTest IP availability

2. not set the request interval, even with dynamic IP to simulate the rhythm of human operation, it is recommended to add a random delay in the code (0.5-3 seconds)

V. Frequently Asked Questions QA

Q: Is there a risk of data leakage with shared IP?
A: regular service providers such as ipipgo using independent authentication mode, each user has an exclusive channel, and the entire data transmission encryption

Q：How to deal with the emergency when I meet the website IP blocking?
A: Immediately switch the country node + modify the User-Agent combination, ipipgo supports simultaneous calls to residential IP resources in multiple countries

Q: What if I need to collect data from different regions at the same time?
A: Using the geolocation function, ipipgo's IP pool can be accurate down to the city level, and multiple geographically exclusive IP pools can be run in parallel

For small to medium sized crawler teams, it's important to choose someone like ipipgo who can provide the90 million+ real residential IPsThe service provider, which does not require the high investment of self-built servers, can also flexibly respond to a variety of anti-climbing strategies. Especially in the mixed use of dynamic IP and static IP, it is recommended to do AB test according to business scenarios to find the most cost-effective combination of programs.
