Review: robtex.com – DNS and Peering Tool

I needed to test some DNS configurations today and came across the an fulsome tool for gathering information about your websites, you hosting provider and their connectivity. AND it still has some amazing DNS, Blacklist and Peering information. Here with is a pictorial on the function of the website.

Head on over the Robtex

This is an treasure of information. I can see my hostname and domain being resolved and then the IP addresses and the BGP AS is shown.

Selecting the tab at the top will automatically do a lookup on most of the Blacklist providers to tell you if your domain is listed for bad behaviour.

The Etherealmind View

This is an amazing tool. Since I only need to access this type of information once or twice a year I don’t keep up with the latest tools and techniques. Having the information presented in compact, and hyperlinked form that can model the IP address, the domain name, the BGP AS, and map the connectivity between all the different elements is astonishing.
