I have a network which was setup as a standard 192.168.1.1 /24 range. This was fine and should have been plenty of addresses for the network.
However the company expanded unexpectedly and they installed a new production line. The range would have been fine for the expansion of PCs however the people that put the production line in stuck all the components on the network and took up 105 IP addresses. Another company then came along and put a camera and door security system in and took a load more IPs.
So now I'm looking at a network with only about 10 ip address left and they are planning on buying iPads for the sales team.
What I'm trying to establish is if I can expand the IP range without additional hardware? And if so how do I go about extending the number of IP addresses I have?
The main network of PCs need to be able to see the production line devices for monitoring and reporting.
Here's where it might get tricky. Getting the 3rd party company to change the static IP settings on their components may not be easy. As a last resort we may be able to get them over to do it, but they are in Germany and we are in the UK. So it might be expensive to do.
Changing printers and the security system shouldn't be a problem.
I've attached a diagram of our current network layout.
Any help or advice would be greatly appreciated.
