Hi!

I have a question about VLSM design. Let's take the example from the Study Guide on page 138.

So, we have following subnets:

1) 192.168.10.0/27 (30 valid hosts, 25 used)
2) 192.168.10.32/28 (14 valid hosts, 13 used)
3) 192.168.10.48/28 (14 valid hosts, 10 used)
4) 192.168.10.64/29 (6 valid hosts, 6 used)
5) 192.168.10.72/30 (2 valid hosts, 2 used)

My question: what should I do if I will need to expand the subnet 10.48 to 30 hosts after network is designed and functions? How to solve expanding issues with VLSM design?

Thanks ahead.
