OTTool — a free utility from Neon Software that provides a synopsis of the IP and AppleTalk configuration parameters within Apple’s Open Transport networking architecture — has support for Mac OS X, in addition to Classic Mac OS, as of the new version 1.2.
OTTool also lets users on IP networks make Domain Name Server (DNS) queries, ping devices using ICMP Pings, trace IP routes (UNIX traceroute), scan through ranges of IP addresses asking for resolutions, and query a DNS for Mail Exchange and System Info, according to MacTech magazine. On Classic Mac OS PowerPC machines, it will also display the IP ARP cache.
OTTool 1.2 will run natively on Mac OS X and Classic Mac OS 8.x and 9.x, all from a single application. Plus, it has added some minor user interface improvements. You can grab a copy from Neon Software’s download site.
