During VLSM addressing, how do I configure a IP address range when a n

Level 1

So the network ID I’m using is 192.150.3.0 /22. I’ve been asked to make an addressing scheme for 4 LANs

I’m confused as to how the host ranges work when the host number is large( all the online examples show a small host amount of bellow 255). Also since it’s 192, I’m working with class C CIDR values?

Say the largest LAN has 400 hosts. I use subnet mask /23 which in total hosts 512 hosts.

Now with my network host ranges, how would we write the range does the 3rd oclet change? Would this be 180.150.3.1 - 180.150.4.254?

Now with my network host ranges, how would we write the range does the 3rd oclet change? Would this be 180.150.3.1 - 180.150.4.254?  - do not believe this can be done.

example :

All 128 of the Possible /23 Networks for 192.150.*.*

192.150.0.0 192.150.0.1 - 192.150.1.254 192.150.1.255
192.150.2.0 192.150.2.1 - 192.150.3.254 192.150.3.255
192.150.4.0 192.150.4.1 - 192.150.5.254 192.150.5.255

All 64 of the Possible /22 Networks for 192.150.*.*

192.150.0.0 192.150.0.1 - 192.150.3.254 192.150.3.255
192.150.4.0 192.150.4.1 - 192.150.7.254 192.150.7.255

So you only have option i can see if you looking 192.150.3.X and 4.X network required in same pool use /21

All 32 of the Possible /21 Networks for 192.150.*.*

192.150.0.0 192.150.0.1 - 192.150.7.254 192.150.7.255
