My friend has installed ISA Server 2004 and i helped him on phone.i couldn’t see what he was doing.i asked him to enter the range of the network.and he entered 192.168.1.1 to 254 with mask 255.255.255.0 instead of entering 192.168.1.0 to 255.
he says every thing works fine.but i have a question in my mind.in this way of giving address range we have omitted 0 and 255 that are subnet address(0) and broadcast address(255).why is the network working fine.or what flaw or problem does it cause??
