DNS Tools

This is a collection of utilities that I have used since my early days at XO Communications

Accessible at: http://dns.kittell.net

Available Tools:

1. Name Server (NS) Lookup
   • To use this part of the tool:
     • Type a domain/host name into the box on the top
     • Select the desired record type
     • Select server to lookup against
     • If you want to use a custom server type a server address (host/domain name or IP) in the other server box and it will automatically change the server drop down box to “Other”
     • Click on the “NS Lookup” button and the result will show up in the screen below
