At this point I was kicking myself in the butt for not being better prepared. I had never expected to get this far in such a short time. Now that Alisa had found the latest release of the source code and compressed it into a single file, I needed to walk her through the steps required to send me the file. But I couldn’t give her one of the hostnames I was using, and obviously I didn’t have a hostname that ended in Motorola’s " mot.com ." I thought of a work-around: thanks to my knack for remembering numbers, I knew the IP address of one of Colorado Supernet’s servers, named "teal." (Each reachable computer and device on a TCP/IP network has its own distinctive address, such as "128.138.213.21.")
