Check your best DNS server (Fast and nearby)

Written by Xaus Xavier Nadal on August 28th, 2011

Good,

Today I show an open source application extremely useful for improving code performance servers DNS Local and improve the performance of DNS queries to the internet by releasing internal DNS load and speeding the delivery of responses from the DNS to our computer, server or network.

The idea is to detect what is the fastest DNS, with better response time and closest possible through an application developed to make a series of performance tests to detect internet which is the best DNS for our teams.

At home it is very simple, run the program, collect data and modified your router or in your local area IP of the DNS assigned to your teams that indicates the program.

In a company you will have to run the program from all points with access to internet, ie if disponéis proxy server you should run the program from each delegation / site with direct access to the Internet and every ISP and geographical location has closest DNS servers and faster than others, so if a company has contracted an internet line with Telefónica and another is with Telmex, Axtel, at & t, etc ... should run the program in each of these outputs to the internet with a computer that has access via those networks.

The program can download it from the following link:

http://code.google.com/p/namebench/downloads/list?can=2&q=namebench

It is available for Mac, Windows and of course the source code is also available through Python.

I can run from a server it does not perform any installation. It's a portable version.

You can find more information about the program at the following link:

http://code.google.com/p/namebench

I explain a bit about what you must do to remove the fear of the newbies.

Download the program, run it and you will see a screen similar to the following:

Improve DNS

just click on Start Benchmark.

The options can change at your whim, and the defaults are fine but you can modify to suit your organization.

It will show a results page with the various tests made by the program and its results.

Improve DNS_2

At the top right you will see which is your best DNS server, so; take these ip's and put them in your computer, router or dhcp server for delivery to your customers, you can also set them as forwarders of the DNS in your domain, but I recommend using Root Hints for DNS servers as they are more effective, we'll talk about them another time.

Greetings and see you soon.
