Proxy ip server: Proxy ip server principle and build configuration

What the hell is a proxy IP anyway?

For example, you send a friend a courier do not want to expose their home address, find a courier collection point transit. Proxy IP server is equivalent to this "collection point", it uses its own address to help you send and receive network requests. The common proxy on the market is divided into three types:

① Dynamic Residential IP - It's like a magician who changes his face, changing addresses every time he connects.
② Static Residential IP - It's like a fixed landline number. The address stays the same for a long time.
③ Data Center IP - Mass-produced "industrial products" for server rooms, low-cost but easy to identify

Build a proxy server yourself? Don't wait to read this first

Can you get a server and install Squid to use it as a proxy? Theoretically, yes, but in practice there are too many pitfalls. For example, using Nginx reverse proxy configuration:

server {
    listen 3128;
    location / {
        resolver 8.8.8.8;
        proxy_pass http://$http_host$request_uri; proxy_set_header Host $http_host; proxy_set_header
        proxy_set_header Host $http_host;
    }
}

This is a simple configuration, but there is a fatal flaw - IPs are easily blocked. If you maintain it yourself, you'll have to worry about IP pool updates, request distribution, failover and all that crap, so it's better to just get an off-the-shelf service and save yourself the hassle.
