Ipv4 and ARP tables:

On receiving the ping, host B sends an ICMP Echo Reply packet to host A. Host B looks up its routing table (partial table shown below) using the IP address ____________ and finds that the gateway is ___________. Host B then looks up the ARP table using IP address ___________. Assume it does not find the required entry to map the IP address to the MAC address of the default gateway. Host B then uses ARP to obtain the required entry and uses it to forward the IP datagram.

The ARP request and reply frames, ARP table and IP datagram are shown below the routing table. Provide the required addresses in the frames, table and datagram.
