Consider a router that interconnects subnets A and $B,$ as shown in the figure below. Suppose all of the interfaces in each of these two subnets are required to have the prefix $43\mathrm{.}81\mathrm{.}112./24($i$.$e$.$ a $/24$ CIDR portion of the IP space is provided$).$ Also suppose that Subnet A is required to support $120$ interfaces and Subnet B is required to support $29$ interfaces.

: What would be a valid assignment of network and broadcast addresses $($of the form a$.$b$.$c$.$d$/$x$)$ for these$-$two subnets?

: What would be a valid assignment of IP address, network mask and default gateway for one of the hosts in Subnet A$?$
