From the Network Toolbox home page: "Network Toolbox is a freeware tool to examine both the network settings on your Mac, and your local area network. In addition, it can perform basic functions such as DNS lookups, pings, and trace routes." The software allows you to examine OT Status, Network Interfaces, TCP Status, UDP Status, Network Addresses, DNS Lookup, Ping, Trace Route, ARP Cache, Route Status Report, AppleTalk Status, and the AppleTalk Names List.

Also, if you have an older Mac, be sure to check out the "Classic" applications page for more options.
Finally, take a look at ALEMIA if you think you know that name of an application, but aren't quite sure.
No, I don't accept reviews anymore for these older applications. With the creation of this page in the Orchard's late 2005 redesign, I only accept reviews for currently-developed applications that work on Mac OS X (or later....whatever that might be!!).
