DHCP scope question
Posted on 2009-04-08
We are running out of IP addresses on our DHCP server and need to increase the number of hosts on DHCP. Currently we have DHCP set on Windows 2003 Server x32 Standard SP2 with the following details:
Start IP Address: 192.168.4.1
End IP Address: 192.168.4.254
Subnet Mask: 255.255.254.0 Length: 23
With our subnet I would assume we would get 510 addresses. Am I correct? If so can I just change the End IP Address to 192.168.5.254 to get the additional IPs?
We have a number of Cisco Catalyst switches connected with VLANs and having subnet 255.255.254.0 already present in it. Is there something else we would need to change in the network to make sure nothing breaks once we make this change? We are planning to reboot all the hosts when we do this. Please advise. Thanks.
