Realization of dial-up proxy ip: ADSL dial-up dynamic replacement of proxy IP address implementation plan

ADSL dial-up proxy IP in the end how to play? Hands-on teaching you dynamically change IP

The old iron people who are engaged in web crawler or batch registration must have met the bad thing of IP being blocked. the old technology of ADSL dial-up has now become theDynamic IP switching is a lifesaverIf you want to use a proxy IP address, you can use ipipgo's proxy service to change the IP address randomly like riding a roller coaster. Today, how to nag ADSL dial-up and proxy IP into a piece of use.

First, ADSL dialing principle seconds to understand the version

Home broadband changes IP every time you disconnect and reconnect right? This is the characteristic of ADSL dial-up. All we have to do isProgramming the router to control timed redialingThe proxy server with ipipgo does the secondary forwarding. To give a chestnut: the router IP change once, the proxy server also followed the change of armor, the target site can not tell whether you are Zhang San or Li Si.

 Python simulation of dialing operations (using Huawei router as an example)
import requests
def reboot_modem():
    url = 'http://192.168.1.1/api/device/control'
    params = {'action': 'reconnect'}
    requests.post(url, auth=('admin', 'password'))

Second, four steps to build a dynamic agent pool

1. Get a router that can flash firmware (recommended ASUS/Xiaomi)
2. Install a timed task plug-in and set it to redial automatically every 10 minutes.
3. open a dynamic residential package on the ipipgo website and get the API key
4. Plug the following piece of configuration code into the crawler program:

 Example of ipipgo proxy configuration
PROXY_API = "https://api.ipipgo.com/get?key=你的密钥"
proxy = requests.get(PROXY_API).text
requests.get(url, proxies={'http': f'socks5://{proxy}'})

III. Five practical guidelines for avoiding pitfalls

Pit 1: No IP change after dialing?
Check that the router is not on fixed IP mode, to select thePPPoE auto-acquisition

Pit 2: Proxy can't connect?
Test connectivity with the curl command first:
curl --socks5 proxy IP:port http://ip.ipipgo.com/check

Pit 3: Carriers limit the number of times you can dial?
Don't set the redial interval too short, it is recommended to change it once every 15-30 minutes, which is the most stable.

four. why choose ipipgo dynamic residence packages

The best thing about their home is thatSupport socks5 direct connectionThe first one is the HTTP proxy, which is less likely to be recognized than the HTTP proxy. The last time I helped a customer do e-commerce price monitoring, using his TK line package, ran for a month without triggering anti-climbing.

V. Quick questions and answers to frequently asked questions

Q: How long does it take to get a new agent after dialing in?
A: ipipgo's API is real-time responsive, and new IPs can be acquired within 3 seconds of successful dialing

Q: How to choose between dynamic and static IP?
A: need to maintain long-term sessions (such as hang games) with static IP, short-term tasks with dynamic safer!

Q: What programming languages are supported for calling?
A: the official Python/Java/PHP SDK, other languages with REST API can also be docked!

Finally give a tip: the dialing script and proxy to get the interface into a microservice, with a message queue to control the pace of IP replacement, so that neither frequent switching leads to inefficiency, but also to ensure business continuity. There are technical problems of the old iron can directly find ipipgo technical support, their 1v1 customized solutions can really solve a lot of oddball needs.
