robtex: "swiss army knife internet tool"

robtex has a pretty cool web frontend to the DNS database. You put in an
IP or domain and it brings back DNS related information.   

As an example, I put in nycbug.org: 
http://www.robtex.com/dns/nycbug.org.html

When you click the MX record (fulton.nycbug.org) you get standard DNS
stuff.  But if you scroll down you get the 'value-add' of having that
all that data in a database.  There is a small heading that may help:
"domains using this as mailserver"

Hope that helps.
