How does IPv4 Subnetting Work?
Each computer(all 2 of them) can ping the router but can't ping each-other and firewall is off. Same default gateway, IP address very similar (just two number away at end) but the subnet mask is different between these two computers. One ends in 192 the other 224. There is a switch between them that then connects to the router.
Why can't the computers ping each-other?
