Would it not be doable for a single router in a LAN to assign a number of community ID’s to it is hosts? For instance:

192.168.1.0/24 and 192.168.2.0/24, for a complete of 508 usable hosts underneath 2 completely different community ID’s. (simplicities sake I will be utilizing examples underneath /24)

I’m conscious you’ll be able to subnet into 192.168.1.0/23 or use the 172.16.x.x handle in order for you greater than 254 hosts underneath a single router. I’m simply curious if the a number of community ID instance (192.168.1 & 192.168.2) is feasible as an alternative.

Would the router itself must be underneath the identical community ID as what it offers out as hosts? For instance, it must be 192.168.1.0/30 with a purpose to give out IP’s to a subnet of 126 usable hosts underneath 192.168.1.4/25, as an alternative of 254 usable hosts underneath a unique community ID of 192.168.2.0/24

If this isn’t doable, the place does the break occur in a LAN the place a number of completely different community ID’s exist? Eg. 192.168.1.0/24 and 192.168.2.0/24. I am confused as a result of the subnetting examples I realized from solely present a LAN being underneath a single community ID, however in non-public addressing, all of the community ID ranges of for instance, 192.168.x.0/24 are usable.
