WhatRoute is designed to find the names of all the routers an IP packet passes through on its way from your Macintosh to a destination host. It also measures the round-trip time from your Mac to the router, thus enabling you to determine slow links--or hops--in the Internet. WhatRoute can also find dead links, such as routers that don't respond. This program is optimized for use with Open Transport. What's New: A bug in rendering text on MacOS X 10.2.5 has been fixed |
