I’ve learned more about networking in the last week than I did in the past year.
DSL modems, such as the Westell Wirespeed, typically assign IP addresses based on MAC address. The MAC address is supposed to be a unique identifier for every piece of networking equipment. Of course, I’d always known some ISPs limit usage based on MAC address filtering. What I didn’t know is that MY ISP did, and the way in which they did it.
When the modem has assigned an IP to a requester, it won’t give out any more IPs. It will only give out one IP to one and only one MAC address.
