> NetLab 1.4 has an expansive, powerful tabbed interface chock full of internet utilities. It includes Finger, WhoIs, clock synchronization, quotes, ping, traceroute, DNS, and domain scanner tool. After familiarizing with the application for a few minutes, any computer aficionado can access unlimited amounts of information.

netlab is kewl and has more stuff.
I have both, but for people who could become overwhelmed at all the "chocked" stuff I recommend NeoTrace for newbies.
ALSO, an important feature is the nice beeps, and color-coded stuff. funstuff
