This is our current configuration for our dhcp server/router.
ip dhcp pool ncore-pool
network 192.168.134.0 255.255.254.0
As you can see we are using a .254 subnet mask
However, one host was getting
192.168.134.255 as an assigned IP address.
Being that we are using a /23 mask. Wouldnt the host still be able to connect
to our network, as .255 is no longer
the broadcast address of the subnet?
she was unable to until i excluded
192.168.134.255 from the dhcp and
she was given another ip address
From the perspective of the Cisco router using 192.168.134.0 with a /23 mask if legitimate and the user should have been able to connect and to access resources. But there are some devices (some OSes - and I think that it includes at least some versions of Windows) that see 192.168.x.x and automatically treat it as a /24 and do not recognize the supernet that you are attempting to use.
