Step 1: Open Settings

First, you need to open Settings on your iPhone or iPad. On the home screen, tap the "Settings" icon, which will take you to the device settings page.

Step 2: Select Wi-Fi

In the device settings page, select the "Wi-Fi" option. This will display a list of available Wi-Fi networks.

Step 3: Select a network

In the Wi-Fi network list, select the network you want to connect to. Then, in the network details page, scroll down and find the "HTTP Proxy" option.

Step 4: Configure the proxy server

Under the "HTTP Proxy" option, select "Manual". This will open a new page that allows you to manually configure the HTTP proxy server.

In this page, you need to enter the IP address and port number of the HTTP proxy server. If you don't know this information, you can ask your network administrator or service provider for help.

Step 5: Save settings

Once you have entered the IP address and port number of the HTTP proxy server, tap the "Save" button. You can then return to the Wi-Fi network list page and connect to the network.

Now, you have successfully set up the HTTP proxy IP server on your iPhone or iPad. Whenever you connect to this network, your devices will use this proxy server for internet access. This will help protect your privacy and improve your network security.
