Hi All, I need some advice here. I have never been exposed to a network which required more than 1 range of IP's. Usually on the 192.168.0.x range. I have inherited a site with an ip range of 10.5.2.1 - 10.5.3.255 (255.255.254.0) I am going to run out of IP's soon and would like to kinow what would be the best solution to add more IP's

Thanks so much

One option would be to expand (double or more) the range you are currently using. Change it from your current two class Cs (10.5.2.0/23, 255.255.254.0) to four class Cs (10.5.2.0/22, 255.255.252.0). Is this an option?

Note that you will need to update the netmask on any systems that have static assignments in this range, and update any inspection rules.

Thanks for the advice. What exactly are inspection rules?

Just a reminder (since I don't know what your internal network design looks like) that you might have to update internal firewall rules, Linux iptables entries, etc to allow the new range. If you don't have any internal filters, then you don't need to worry about this.
