For each of the following IP addresses, what will the router do if a packet with that address arrives? (a) 135.46.63.10 (b) 135.46.58.16 (c) 135.46.52.2 (d) 192.53.40.7 (e) 192.53.56.7. Assume: Your laptop's Ethernet address is 0a:0b:0c:0d:0e:0f, DHCP server address is 131.111.7.3, your IPv4 address will be 131.111.7.121, the gateway's IP address is 131.111.7.1, and Ethernet address is 00:01:02:03:04:05, the network subnet mask is 255.255.255.0.Write the series of protocol/packet exchanges that occur on the wired Ethernet link, up until you can send a single packet to 128.232.0.20. You do not need to describe packets after this packet has left the link. Include ARP and DHCPUsing packet tracer, implement a network that has the following components: 1- At least five routers 2- At least 7 subnets 3- At least 12 PCs 4- At least 4 switches 5- Use RIP routing protocol To assign IP addresses of the routers and PCs, use the IP address from your ID as follows Assume your id is 118zyxw, Consider the numbers z, y, x and w as deciemal You have the subnet 118.0.0.0/24 If your ID is 1181234 then the IP is 118.0.0.0/24 Use this subnet to get at least 7 subnets.

- After establishing a connection with the local DNS server PC1 now knows the IP and MAC addresses of PC2. Suppose PC1 [IP Address: 192.168.2.1, MAC Address: 0010.1191.A946] is sending an ARP packet to PC2 [IP Address: 192.168.2.2, MAC Address: 0110.1290.AD23]. What will be written in the target MAC address before the packet reaches PC2 ?It has a total of four routers. Every single one of the four distinct kinds of routers Does router A need to recompute its distance vector as a result of the addition of routers B and D to the network as a result of the construction of a new link that connects routers A and C? The DV (distance vector) algorithm is the routing mechanism that is employed by the RIP protocol, which is executed on the routers.A Network with id: 192.168.0.0 and subnet mask 255.255.0.0 is given to you to split it in such a way thatfollowing classrooms are given adequate number of IPs based on their needs. Each classroom willoccupy its own subnet. The following information for each subnet must be included: Subnet ID CIDR Subnet Mask First IP usable in the subnet Last IP usable in the subnet Broadcast IP Address for the subnet Classroom1: 8 PCsClassroom2: 400PC and 4 PrinterClassroom 3: 2 PCsClassroom4: 62 PCs and a ServerClassroom5: 24PCs
