http quality proxy: quality HTTP proxy screening configuration program

What's the best way to choose an HTTP agent?

A lot of old iron in the selection of proxy IP have stepped on the pit, obviously look at the parameters are good, with either slow speed or always dropped. In fact, picking a proxy is like buying a watermelon, just look at the grain enough to shoot. We have to focus on three hard indicators:Survival rate, response time, IP purity. For example, ipipgo's dynamic residential agent, the measured survival rate can reach 98%, which is 5-8 percentage points higher than the peers in general.

Hands-On Proxy Quality Measurement

Don't just listen to merchants blowing, do-it-yourself measurement is the most real. Prepare 20-30 test IPs and run a round with this Python script:

import requests
proxies = {'http': 'http://用户名:密码@ip:port'}
try.
    resp = requests.get('http://httpbin.org/ip', proxies=proxies, timeout=5)
    print(f "Successful connection, response IP: {resp.json()['origin']}")
except Exception as e.
    print("Proxy failed or timed out.")

Focus on two numbers:Success rate below 90% direct passes, response of more than 3 seconds is recommended as a spare tire.

There's a way to configure it. It's all for naught if you don't set it up right.

Getting a good agent who won't match is also spoiling things, remember these three tips:
1. Don't wait for the rotation interval, according to the business volume dynamic adjustment. For example, the crawler business is recommended 2-3 minutes to change the IP
2. Geographic selection should be precise, do business in Europe and the United States, do not choose Japan and South Korea nodes
3. protocol matching is very important, http business do not use socks5 proxy (although it can be used but the efficiency of 80% discount)

Guide to avoiding pitfalls and saving money

I've seen too many people pay a lot of money for enterprise level packages that don't work at all. Remember the formula:
Daily usage <10GB select standard version | 10-50GB with Enterprise Edition | Static IP for fixed services
Static residential proxies like ipipgo's support 35 bucks a month, which saves half the overhead over per-traffic billing.

QA First Aid Station

Q: What should I do if I can't connect to the agent all the time?
A: Check the whitelist settings first, then test the local network. ipipgo client comes with a diagnostic function to detect port blocking in one click.

Q: What if I need multiple regional IPs at the same time?
A: Just add the country parameter to the extraction API, such as&country=us,gb,jpIt will be able to rotate the US, UK and Japan nodes.

Q: What's so expensive about the corporate package?
A: The main difference is in the exclusive channel and priority, and the measured concurrent request speed of the Enterprise Edition is 2.3 times faster than that of the Standard Edition.

Why do you recommend ipipgo?

This dynamic residential agent has a masterpiece - theCarrier-grade IP poolsThe first thing you need to do is to use a real home broadband IP. Simply put, the real home broadband IP, unlike some businesses with virtual machine IP to fill the number. The success rate of using his proxy over the authentication code can be measured to 82%, which is higher than the data center IP by a large margin.

Highlighting theirTK LineThe TK Dedicated Line is especially suitable for business scenarios that require high concurrency. Last time to help customers configure the crawler system, with the standard agent can only run to 200 requests / second, cut to the TK line directly soared to 1200, and the cost of each 10,000 requests to spend more than 3 cents.

There's something to be said for package selection:
- Individual developers go straight in with their eyes closedDynamic residential (standard)I've been playing for half a month at $7.00 a gig.
- Workshop selectionStatic homes35 fixed IPs to save energy and effort
- On enterprise-level projectsDynamic Residential (Business), $9.47/G with exclusive tech support

Lastly, don't be fooled by unlimited traffic packages, which tend to limit the number of concurrency. ipipgo's stepped pricing is more cost-effective instead, how much to use how much to count, and at the end of the month, you can't use up all the traffic can also be carried over.
