Multi-region proxy IP: Designated city-level geolocation proxy

First, what is the city-level proxy IP, to give a chestnut to understand

Imagine you're doing something online that requires alocal identity card, such as to check the takeout deals in a certain city, grab concert tickets or test the regional services of an APP. Ordinary proxy IPs are like borrowing someone else's ID card at random, while city-level proxy IPs are specialized for you toCustomized proof of residence on a particular street. For example, if you use ipipgo's Shanghai Jing'an proxy, the server will 100% recognize you as a local resident user.

The biggest difference between this thing and a regular proxy isPositioning granularity. Ordinary proxies may only be accurate to the province, while our technology can do it to the district and county level. For example, if you want to test a certain local life service in Yuhang District, Hangzhou, using ipipgo's Yuhang node is ten times more reliable than using a generic proxy in Zhejiang Province.

Second, what the hell can this thing do? Three real-world scenarios

Scenario 1: A must-have tool for e-commerce price comparison
A branded cell phone sells for 4,999 in Beijing, but may sell for 4,899 in Chengdu. ipipgo's Chengdu agent account number, immediately see the real regional price. If you've done e-commerce, you know that different cities' promotional strategies can make a difference in the cost of shipping.

Scenario 2: Local service validation is just needed
To develop a city delivery APP, you need to use a local proxy to see the real service scope. Last time a customer with a national general IP test, die show "temporarily does not support the region", replaced with ipipgo Suzhou node immediately normal.

Scenario 3: Data collection without stepping on puddles
Climbing a certain government website to check the policy of each district, using the national general IP is easy to be blocked. Change to ipipgoMulti-city rotation strategy, every hour automatically switch different district and county IP, the collection of success rate directly pull full.

Third, hand to teach you to choose the right service provider

There are quite a few on the market that claim to be able to do city positioning, but there are too many pits in the real test. Remember these threeGuide to avoiding the pit::

A special reminder to watchFrequency of IP updatesThe IP pool of some service providers is not updated for three months, and has long been blacked out by major platforms. ipipgo replenishes 15% new IPs every day, and you can check the freshness of IPs with this script:

import requests
proxy = {"http": "http://ipipgo_username:password@cn-hangzhou.node.ipipgo.com:9020"}
resp = requests.get('https://ipinfo.io/json', proxies=proxy)
print(resp.json()['ip'], resp.json()['city'])

Fourth, the configuration of the tutorial can also be handled by the white man

Take the crawler project as an example of a three-step process for pinpointing:

Step 1: Pick a city code
Log in to ipipgo backstage and search for the city ID, for example, Chengdu Wuhou District is cd-wh

Step 2: Dynamically set the request header
Don't be stupid and use a fixed IP, you'll get blocked:

headers = {
    'X-Proxy-City': 'cd-wh',
    'Authorization': 'Bearer your_api_key'
}

Step 3: Automatic Rotation Strategy
Set every 50 requests to change the IP of different districts in the same city, so as to maintain the geographical attributes and security.

V. First aid kits for common problems

Q: Is it illegal to use this?
A: As long as you don't engage in false registration, single brush these tawdry operations, normal business needs are completely legitimate. ipipgo all nodes have been filed by the Ministry of Public Security, rest assured with.

Q: What if I need to switch cities frequently?
A: Turn it on in the account settingssmart modeIt supports automatic switching by hour/times. Last time a customer to do national house price monitoring, set every 20 minutes to cut a city, stable run for three months.

Q: What should I do if I encounter a sudden IP failure?
A: The first time to go to the official website to check the node status, ipipgo has a real-time monitoring page. If there is indeed a problem, just add a retry parameter to the API request:

params = {
    'retry': 'auto',
    'fallback_city': 'sh-pd'
}

As a final word of caution, don't buy those volume-based shared IP pools on the cheap. For city-level business, look for something like ipipgo.Exclusive IP + Precise PositioningThe service provider that saves you from losing your seal is enough to buy ten years of service.
