create an IP network design for a small office with 4 subnets and 50 host addresses. One subnet will be the HR Department. All inbound and outbound traffic from the other subnets will be denied access to the HR Subnet
For a class C network address (i.e /24), you need to borrow 2 bits from the 4th octet to get 4 subnets, the remaining 6 bits will give you 64-2=62 hosts, which is enough for your 50 hosts. So the final subnet mask would be /26.
