Table 3.20 is a routing table using CIDR. Address bytes are in hexadecimal. The notation /12" in C4.50.0.0/12 denotes a netmask with 12 leading 1 bits: FFF0.0.0. Note that the last three entries cover every address and thus serve in lieu of a default route. State to what next hop the following will be delivered: (a) C4.5E.13.87 (b) C4.5E.22.09 (c) C3.41.80.02 (d) 5E.43.91.12 (e) C4.6D.31.2E (f) C4.6B.31.2E Table 3.20 Routing Table for Exercise 72 Net/MaskLength C4.50.0.0/12 C4.5E.10.0/20 C4.60.0.0/12 C4.68.0.0/14 80.0.0.0/1 40.0.0.0/2 00.0.0.0/2 Nexthop
