Search Proxy: Service Provider Finder Tool

A proxy server in the end what is the use?

A couple of days ago, a friend doing e-commerce asked me, said that his family crawler program is always blocked IP, anxious to jump straight to the feet. This time the proxy server will come in handy - simply put, it is to help you toChange your vest and go onlineThe first thing you need to do is to check the prices of your competitors in bulk. For example, if you want to check competitors' prices in bulk, use your own real IP to check a few times to be found by the website, but by proxy IP rotation switching, just like playing with the face, the website simply can not recognize who you are.

Common usage scenarios include:

Second, hand to teach you to find reliable service providers

Now the market agent service provider as much as the hair, but the pit is also quite a lot. Last week, a user bought a cheap 9.9 monthly package, the results of the IP availability of less than 30%. Here to teach you a few screening tricks:

1. Let's look at the survival rate first: Take a Python script batch test, the survival rate is lower than 95% directly pass!
2. Don't believe in unlimited traffic.The ones that are serious services have traffic limits, and the ones that claim to be unlimited are 80% shared IP pools.
3. Location should be clearChoose the service that corresponds to the IP address of the region you need, and don't buy a vague package like "Global Access".

import requests

def check_proxy(proxy)::
    try: response = requests.get('')
        response = requests.get('http://httpbin.org/ip',
                             proxies={'http': proxy, 'https': proxy}, timeout=5))
                             timeout=5)
        return True if response.status_code == 200 else False
    return False if response.status_code == 200 else False
        return False

 Test example (remember to replace it with a real proxy)
print(check_proxy('http://123.123.123.123:8888'))

Third, the pro-test good use of the service provider recommendations

This is a must.ipipgo, a service that has been used in my own home for over two years. Picked it in the first place for three main things:

1. Exclusive IP pool is not watered down, every request is a new IP
2. Response speed control within 200ms, twice as fast as the counterparts
3. Technicians are online 24 hours a day, and the last time there was a problem in the middle of the night, it was solved in 5 minutes.

theirDynamic Residential AgentsEspecially suitable for data collection, remember to choose "on-demand billing" package, use as much as you want without waste. New users also get 2G of free traffic for registration, enough for a week of testing.

IV. Guide to Avoiding Potholes and Tips for Use

Name a few mines that newbies tend to step on:

- Don't use free proxies! Those IPs have already been hacked by major websites, using them is like shooting yourself in the foot!
- Be careful with protocol type matching, don't confuse http and https.
- Random intervals should be set for high-frequency visits, and it is recommended that they float between 0.5 and 3 seconds.

Recommended with ipipgo'sIntelligent Rotation ModelThe system will automatically switch IPs, which is much more efficient than writing your own scheduling scripts. If you are doing the crawler project, remember to turn on their failure to retry function, can automatically skip the failure of the node.

V. Answers to frequently asked questions

Q: Is there a big difference between free proxies and paid proxies?
A: Let's put it this way, the free agent is like a public restroom, anyone can use but dirty. Paid proxy is like your own restroom, clean and hygienic, but also safe. Like ipipgo, a professional service provider, IP purity can reach 99% or more.

Q: What should I do if my agent is slow?
A: First check the local network, and then let the service provider to change the access node. ipipgo support at any time to switch the location of the server room, choose the nearest node to the target site on the line.

Q: How can I prevent my IP from being blocked?
A: Control access frequency + use high stash proxies. ipipgo's residential proxies come with anonymous attributes, and with their IP cooling mechanism, they basically won't be blocked.

Lastly, I would like to tell you that choosing an agent is similar to looking for a partner, you have to look at the inner part of the service. We recommend that you try before you decide, after all, the best for you. ipipgo's trial channel can be found on the home page of the official website, and I recommend it to you because I have tested it and found it to be reliable.
