The Lucent AP-1000, the access point that's rapidly becoming the standard for use in corporate or campus networks, can store a list of as many as 492 MAC addresses that have permission to access the network. If a MAC address hasn't been added to the access point, it is rejected, and the user can't connect to the network. This technique has the added benefit of keeping the bad boys from spoofing IP addresses. If you can't get on the network, you can't spoof an address. Robert Currier has been in data networking for more than 15 years, the last five as Director of Data Communications at Duke University.
Currier is an accomplished writer, public speaker, and photographer.
