Re: Which servers support secondary network numbers?

["James E. Drews" <[e-mail]>]

Cisco (and others I am sure) can can assign more than one ip range to
each port/wire.  For example, on one port of a Cisco router you can
assign the ip range:  144.92.4.0 (subnet mask 255.255.255.128). Then
sometime down the road when you add more machines to this network and you
need more IP addresses, Cisco (and others) will let you add a second
address range to the same wire.  The catch is, when a DHCP/BOOTP request
gets forwarded on from the NEW range, usually the gateway address in the
packet will be from the original range.  This causes DHCP/BOOTP servers
to assume the incorrect address range for the machine.  Some servers
DHCP/BOOTP have worked arround this problem.

Is that enough elaboration?
