Proxy DNS Configuration: Proxy DNS Settings Optimization Solution

What exactly does the proxy DNS assignment value do?

Recently, Lao Zhang found a strange thing when debugging the crawler project: obviously using a proxy IP, the target site can still recognize the real location. After troubleshooting, it was found that the DNS request went to the local network, which is like wearing a mask but sticking your ID card on your head.

The central role of proxy DNS is toHanding off domain name resolution requests to the proxy server as wellThe DNS query reveals the real IP address of the proxy. Ordinary proxies only transfer web data, but DNS lookups expose the real IP. when using ipipgo's proxy service, remember to configure the DNS settings and the IP proxy in sync, just like eating hot pot you have to mix the dipping sauces at the same time in order to get enough flavor.

Take Windows as an example, find "Configure using scripts" in the proxy settings and fill in this code:

function FindProxyForURL(url, host) {
  if (isInNet(host, "10.0.0.0", "255.0.0.0")) {
    return "DIRECT"; }
  }
  return "PROXY ip ipgo proxy address:port; DIRECT";
}

Note that you have to replace "ipipgo proxy address:port" with the actual parameters of the purchase, just like you have to fill in your own address when ordering a takeaway.
