I am having 2 VLAN
VLAN1 - IP range 192.168.1.1 to 192.168.1.99 subnet 255.255.255.0 i.e. I have 100 host in VLAN1VLAN2 - IP range 192.168.1.100 to 192.168.1.199 subnet 255.255.255.0 i.e. I have another 100 host in VLAN2
Now I want to communicate in ...
Ok assuming I used your 2nd idea, Now suppose I have to migrate 1 host from VLAN1 to VLAN2 now do I need to change my IP to other subnet prepared for VLAN2 ?
I observed that even when we use 255.255.255.0 mask just by using VLAN I can separate broadcast domains.
One more thing, what if I take IP range this way
VLAN1 - IP range 10.0.0.0 subnet 255.0.0.0 VLAN2 - IP range 12.0.0.0 subnet 255.0.0.0
