Should configure proxy be on iPhone?

What is configure proxy on your phone?

What you really want to do is have these sites using the same proxy settings as your device.

To that end, if you are on your phone and want to access one of the restricted sites (eg. Facebook) on the desktop use a tool like to find out what settings you would need to put on the site to access it over the proxy.

On your Android (4.0.3) phone:
You should open the browser with an incognito mode, so that the proxy server is bypassed. Otherwise you will not see the proxy information.

Press the Menu button on the top left corner (and not Home, Settings or Back). Open More Tools. Open Developer Tools. At the bottom of the developer tools there should be a network icon. Tap it. You will see a list of all the sites you are connected to. Find the site you need and tap it.

Note that in Android 4.3 the network menu also provides a few more things like battery and data usage.

What is my proxy on my iPhone?

You have probably been able to guess that the proxy is just a simple way of connecting you to the internet when you are behind a company's network and not on your real internet IP.

You normally have an HTTP proxy to do this. But what does it have to do with your iPhone? In reality the proxy you use on your iPhone doesn't have much to do with the HTTP proxy you have on your desktop computer. The proxy that comes built-in into your iPhone is actually Apple's HTTP server. It is a simple app, not a proxy. You can call it your proxy if you like, or I suppose it could also be called a server. Apple just decided to call it their own "server".

Anyway. This is all about it's DNS address. How does DNS get assigned?

DNS is made up of a name server on the internet that is in charge of translating names in IP addresses (domain names) to IP addresses (A record) and visa-versa. Name server. When you configure your iPhone to connect to WiFi networks, you are usually greeted by some kind of name servers you need to resolve for it to connect to the network. This is because most modern websites do things differently when connecting to a public WiFi as opposed to having a connection to your cable or DSL modem. Instead they first go to your router, get the internet ip address of the router and then use that to resolve DNS names. Most routers let you specify what name server your computer is using and also your public ip address. Your macbook or linux or Windows 7 computers will normally default to name servers on the web to figure out things. In the case of my macbook, it connects to my broadband modem on IP 192.168.1 so it gets a name server of 208.67.222.

Your android devices can also use whatever you like. I believe you need to set it manually in adb if you want it to work. The iPhone uses the following by default.

Nslookup. I use the command "nslookup" which queries a domain name by it's hostname and translates it into an IP address. You would input the name of your wifi router as the query name which would then resolve it's dns name.

Should my Configure proxy be on or off?

Do we need to configure the Proxy settings?

Can't we create a proxy just using this line in web. . Are there any performance issues if my Configure proxy is on or off? It has no effect on IE11 but I guess it will work in all browsers, including chrome. The only thing you have to know is that IE7 and earlier proxies will be enabled by default. IE8 enables them by default unless you have been explicitlly disabled them.
