that Web Server ARP Table already contains any MAC address needed
for this packet)
c) (3 points) Source Address in IP header
d) (3...
true or false ? 1) In a network where virtual circuit is used in Network layer , the virtual circuit number is fixed through out the route . 2) If an IP packet is fragmented at a router , the reassembly will be perform in next router. 3) When a client machine first sends out the DHCP discover message , the message destination address should be set to DHCP server IP address. 4) In IPv6 , IP address is 6...
