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

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.
