Need more IP Addresses

By palazzini ·
My network is running out of private IP addresses, currently i am using 172.20.0.1 with subnet of 255.255.254.0.
What is the best way to expand the dhcp server for more ip addersses with out disturbing existing subnet?
I need at least 200 IP addresses more and the users have to get the ip addresses from the same DHCP server.
I really appreciate any help.
Thanks in advance.

palazzini why are you hesitating to promote from class C to class B ip set ? change your net mask from 255.255.254.0 to 255.255.X.0 according to the number of subnets you wish to have . This will "disturb" your subnet . One other trick may be use a NAT server to show a certain amount of pcs in one fake subnet and the others in another pool. This might force two DHCP servers issuing different pools of ip , with NAT on them . But this is bizzare and not a "formal" method. When things go wrong it is difficult to trace .

Also don't forget to adjust the interface
(netmask) on all systems that don't use DHCP!!!.

All netmasks within a subnet should be equal.
