Note: At times (most) I have called DHCP “Dynamic Host Control Protocol.” I’m not sure where I picked that up, but you will see it all over the Internet, including on the web sites of some big players in the network business, such as Microsoft, Intel, and Cisco. I have corrected it in the digest proper, but I can think of no easy way to correct it in this forum.
