im an I.T technician working at my local school. the network has 190 computers currently.
I use windows server 2003, and the network has all the normal servers e.g. File server, admin server, print server.
the DHCP server sends IP's out as soon as machine's are turnt on like they do, talk of another 200 computer to the network has arised recently.
with the 255.255.255.0 subnet mask in my network im only allowed 254 computers right? how can i add another 200 computers to the network with this. Please help me someone im really unsure on what to do when the extra 200 PC's come.
kewl's suggestion would probably be an easy solution. Most of the time, the 192.168.x.x range is used inhome networks.. but 192.168 w\ the 255.255 subnet gives you a maximum of 65,000+ ip addresses to use.
There's really no need to nit-pick and break it down closer... you could also do 192.168.0.0 255.255.254, Which would give you 510 usable ip addresses. or 255.255.252 which would give you 1024 ip's.. but you don't have to worry about conserving ip's since they're private addresses.
You may need to make some changes to your network devices when making this change of ip addresses.
I worked at the community college I was attending, and believe it or not.... they didn't utilize NAT ! Every computer on campus had a unique public ip address. This was the topic of discussion all the time in classes I was taking.
