Exercise 3 We have a network as shown below. The user working at the computer gucio.intranet.pl send command ping www.test.pl Assumptions: 1. ROUTER and all the computers in the subnet 112.168.0.0/24 have no records in their ARP caches, 2. the DNS cache of the computer gucio.intranet.pl is empty, 3. ROUTER and computers in subnet 214.118.8.0/23 have proper records in their ARP caches for the whole subnet, 4. server dns.intranet.pl has got the whole knowledge about all addresses in the network, 5. we use only the first 3 bytes of the MAC addresses - they distinguish one from another the MAC addresses in our network (the broadcast MAC address = FF:FF:FF). IP=112.168.0.1/24 MAC=40:40:40 IP=214.118.8.254/23 MAC=14:14:14 ROUTER dns.test.pl IP=214.118.8.253/23 MAC=23:23:23 DG=214.118.8.254 REPEATER www.test.pl IP=214.118.8.252/23 MAC=31:31:31 DG=214.118.8.254 REPEATER gucio.intranet.pl IP=112.168.0.100/24 MAC=12:12:12 DG=112.168.0.1 DNS=112.168.0.200 dns.intranet.pl IP=112.168.0.200/24 MAC=21:21:21 DG=112.168.0.1 dhcp.intranet.pl IP=112.168.0.002/24 MAC=33:33:33 DG=112.168.0.1 Fulfill the table below, describing the network movement between all devices (computers and ROUTER), till the moment that the computer gucio.intranet.pl receives the answer for its ping command. The The Protocol, message source (the content of the packet or the frame) The source IP address The destination IP address MAC address destination MAC address 12:12:12 DNS request www.test.pl 112.168.0.100 14:14:14
