Wi-Fi settings

DNS is Domain Name Service. It is the “phone book” of the Internet. When you enter a URL such as Official Apple Support Community your browser sends that to a DNS server, and the DNS server returns the IP address of that URL so your browser knows how to find it. Here is the long answer→https://en.wikipedia.org/wiki/Domain_Name_System

There are “master” DNS servers, and local DNS servers. The value in your iPhone settings defaults to your network provider’s local copy; their copy is updated periodically from a master DNS server. But you can choose to use a different DNS server by entering it’s IP address. Two commonly used alternates are 8.8.8.8 (Google’s) or 1.1.1.1 (Microsoft’s).

An HTTP Proxy routes your browser requests through another server rather than directly from your browser to the site, so the site sees the proxy’s IP address instead of yours. Some businesses want you to use a proxy when on their network so they can control what you access, but in most cases you should not need or use a proxy.

Off, except in rare instances of a corporate Wi-Fi network, and in that case your IT department would give you proxy information.

Mr. Finch, would you mind explaining what DNS and HTTP PROXY are?

Thank you kindly!

I thank you very much for this explanation! It is greatly appreciated. Have a wonderful day! 😊
