I am not it try to subjugate your knowledge, but I have 700 dhcp users per
site that uses a 128kbps Wan Link, and they still use some apps over the
link, and they keep coming and going everytime, so my DHCP Lease has a very
short period time duration because i have a limited number of IPs to Attrib,
the users for dns purposes only use local domains, rarely they need to use
remote dns, and I have a Gc per Site, so Bandwith is very important.
