4 character long available domain name generator

Recently I developed a script to find 4 character long  available domain name. We all know that 4 character long available domain name is very difficult to find. Generally all normal keywords are already registered. So I planned to develop an application using that I can search 4 character available domains.

I wrote this script to randomly generate 4 character long available domain names with combination of alphabets a-z and numbers 0-1. In this script I assumed that pronounce ability would not be a major factor because all pronounceable domains are already get registered. And the results were what I was expecting:

• Random a-z domain name generation : 100 %
• Random a-z + 0-1 domain name generation : 100%

Because the processes of this script is utilizing lot of server resources. So I planned to develop a lighter version of 4 character long available domain name generator for you and this lighter version of script will generate list of 10 available 4 character domain names randomly. After every page refresh you will get new list of 4 letter domains.

This 4 character long available domain name generator script is currently configured to find .IN, .COM, .NET, .ORG, .INFO, .BIZ and .US domains but you can easily customize this to look for other domain extensions. To customize this for any other extension you need to add /delete that extension according to all extensions written in script:

if(checkdomain("whois.nsiregistry.net",$current.".com")) {

echo $current.".COM\n<br />"; $i--; }

Now I am going to share that script with you . Save this script as php file and host this file on your hosting server or in your localhost server (To run this application from your localhost server you need to be connected with internet). You can download this script from the given link.
