Configure Google, OpenDNS or any other DNS server on your iOS device to improve the Wireless browsing experience on your iOS device and also check which works better on your device.

If you are one of those who are experiencing some glitches with your WiFi browsing speeds, then you would probably want to looks for the correct DNS server that works well with your iDevice. There are a lot of tools to figure that out, but Namebench is the best among the many tools that are available. The tool is available for the Mac and is completely Open Source.

In this tutorial, we will figure out the fastest possible DNS server for your network, and configure your iDevice appropriately to get to the edge. Before we could get into this thingy, we need to know what a DNS Server is (just the gist of it).

What is a DNS Server?

A DNS stands for Domain Name System. All it does is that, it translates the domain names, which are of the numerical forms into human readable ones. The translations is what it matters when it comes to configuring the DNS servers onto your iDevice. The faster it translates, the better is your browsing experience. If you are interested in knowing more about DNS and how it translates and all those stuffs, Wikipedia has the best and simple explanations for these.

  1. Choose the network for which you want to configure the DNS settings. [You need to be connected to that particular network to configure its DNS]

  3. After typing the DNS Server information, Tap the WiFi Networks button to take you back to the WiFi Settings page!

Recommend some good DNS Servers:

There are two DNS Servers that perform best. The Google’s and the OpenDNS servers. Google DNS works out for most of them, since they have got some huge data farms and never goes down. Here are the addresses for these DNS Servers:

[checklist]
  • Google DNS – 8.8.8.8 , 8.8.4.4
  • OpenDNS – 208.67.222.222, 208.67.220.220
[/checklist]

What effect does DNS servers have on my device? And why should I configure it?

Well, as everyone wants to get the max out of technology, you would be expecting to get the full WiFi speeds for the amount you pay for your bandwidth. These custom DNS servers helps resolve the domain names you query from your device faster than normal.
