Relay Proxy IP: Network Request Relay Link Construction and Security Configuration

How do proxy IPs play with transit links? Teach you to build a channel by hand

Engaged in data collection of the old iron must have encountered this situation: the target site suddenly blocked IP, or access to slow as a snail. At this timeTransfer Agent IPIs a lifesaver, equivalent to the local device and the target server between the rack a "transit station", let's take ipipgo's proxy pool as a chestnut:

 Python request example (remember to replace it with your own API)
import requests

proxy = {
    'http': 'http://username:password@gateway.ipipgo.com:24000',
    'https': 'http://username:password@gateway.ipipgo.com:24000'
}

resp = requests.get('destination URL', proxies=proxy, timeout=10)

This channel has three levels of benefits: 1. Hiding the real IP anti-blocking 2. automatic IP switching to ensure stability 3. encrypted transmission anti-bugging. But do not think that just buy a proxy can be used, improper configuration minutes into the sieve.

Four steps to build a real battle, even a beginner can become an expert

The first step is to select the protocol type first:

HTTP proxy: Suitable for web browsing
Socks5: UDP protocol support for smoother games/videos
HTTPS: Encrypted transmission is more secure

Using ipipgo's Socks5 proxy as an example, the client configuration should pay attention to these three points:

1. Don't fill in the wrong port number (common 24000-25000)
2. Authentication method selects username/password
3. Timeout setting recommended 5-8 seconds

Advanced players can use Nginx as a reverse proxy, which will enable theIntelligent RoutingFor example, if the domestic traffic goes to the telecom line, the overseas requests are automatically cut to the cross-border line. For example, if the domestic traffic goes to the telecom line and the overseas request is automatically cut to the cross-border line, the configuration will look like this:

 Nginx configuration snippet
location / {
    proxy_pass http://upstream_pool;
    proxy_set_header X-Real-IP $remote_addr;

     Automatic failover of failed nodes
    proxy_next_upstream error timeout invalid_header;
}

Three Iron Laws of Safety and Security. One less and you're out.

Seen too many people proxy servers run naked and get hacked, remember these three life-saving settings:

1. Two-factor authentication must be on
In addition to the account password, add a dynamic verification code. ipipgo's Enterprise package comes with this feature!

2. Access to the whitelist should be limited
Allow only specified IP segments to connect, don't let any dog or cat use your proxy!

3. Traffic monitoring is essential
Suddenly there is a surge in traffic eighty percent is being stolen, in the ipipgo background can be set to use the amount of warning

Why go with ipipgo?

Having used seven or eight proxy services, ipipgo has two killer features:

1. TK LineMeasured latency is less than 100ms, more than 3 times faster than normal lines
2. Dynamic Residential IPSupport pay-per-use, small-cost program evangelism

Frequently Asked Questions QA

Q: What should I do if the proxy IP suddenly fails to connect?
A: First check if the account is expired, then test the local network. If ipipgo background display is normal, try to change the access port

Q: Which is better, static IP or dynamic IP?
A: need to maintain long-term sessions choose static (such as raising the number), short-term high-frequency request with dynamic more cost-effective

Q: Can agent speed be increased?
A: three tips: 1. choose geographically proximate nodes 2. switch the Socks5 protocol 3. turn on smart routing in the ipipgo backend

One last trick that only insiders know: ipipgo'sAPI Extraction FunctionSupport for simultaneous access to multiple export IP, with multi-threaded crawlers directly take off. New users are recommended to take the dynamic standard version of the first practice, more than 7 1G traffic trial and error cost is low, with familiar and then on the customized program.
