Re: DHCP MAC Filter

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Unfortunately I can't do this within the switch/router. My department shares
a university building with several other departments (I'm the only one
running DHCP), and most cooperate with using fixed IP addresses. But I still
get users in the building that grab my IP addresses; I do have DHCP
reservations for most of my clients, but want to have a few unassigned IPs
for visitors etc. I'm not too concerned with administrative overhead if you
have a suggestion.

Thanks.
