- An ISP has a 127.3.0.0/16 IP address. Customer A is given a 127.3.0.0/24 group of IP addresses. How many addresses do they get? What is the range of IP addresses they get? (E.g. if A got 2, the answer might be 3.0.0-127.3.0.1) Customer B is given another /24 block immediately after Customer A’s What is the CIDR notation for their block? Customer A and Customer B are physically near each If we want a way to refer to their combined block, what is a single CIDR notation for both sets of IP addresses? What is the subnet mask for this new merged subnet?Consider an IPv4 subnet with private IP address space 166.111.8.0/24. If each IP interface in the subnet needs a distinct IP address, then how many IP interfaces can there be in the subnet?A simple CIDR routing table is shown in Figure 1. For each of the destination IP addresses below, indicate which entry in the table it matches. Indicating none if no routing entry can be matched (hint: given an IP packet, the router will check whether there is a routing entry which can be used to route this packet, by checking the destination IP address in the packet with each routing entry: based on the subnet mask of each routing entry, it can extract the network ID and compare it with each routing entry; if there are a few routing entries which can match, the entry with the longest subnet mask wins). Address Mask Output Port 10.19.0.0/16 1 10.19.128/17 2 10.19.192/18 3 10.19.192/19 4 0.0.0.0/1 5 141.219.2.10 10.10.10.10 10.19.86.141 10.19.193.6 10.19.255.86 10.19.192.18

- The first of these packets is from your computer to the DHCP server telling it to release the lease on your IP address. The next 4 packets renew that lease. Note that the source address on the “DHCP Discover” and “DHCP Request” packets is 0.0.0.0. This indicates that your computer does not actually use its new IP address until the interchange has completed. Also note that the destination address in each of the 4 packets is a broadcast address[1]. It should be obvious to you why the first two packets are broadcasted, but what about the last two? Can you explain this? Answer the questions in your Word document right after you post a snapshot of the DHCP packet screen. (#4)A IPV6 global unicast address is composed of a Global Routing prefix = 2001:0540:FACE, Subnet ID = 0020, and an interface id = 0000:0000:0000:0040. Assuming the IPV6 global unicast address follows the "3+1+4" Rule, which of the following is the correct IPV6 global unicast address representation? %3D %3D 2001:540:FACE:20:40/32 2001:540:FACE:20:40/64 2001:540:FACE::40:20/32 2001:540:FACE::40:20/64Suppose that your computer is assigned with the IP address 126.54.18.81 and the network mask 255.255.192.0, and your friend's computer is assigned with the IP address 126.54.81.18. Are the two computers on the same IP subnet? Briefly explain your answer.

The topology of the network is shown above. The Internet Service Provider (ISP) provides the following information to connect the corporate network to the Internet. The CIDR range given for the company: 124.34.52.0/21 The address of the ISP router (also called "Gateway address"): 124.34.63.254 Configure the network by giving CIDR blocks for each company subnet and IP addresses for each station and router knowing that: For Ethernet 1, we need 514 hosts to connect. For Ethernet 2 we need 50 hosts to connect. For Ethernet 3 we need 123 hosts to connect. For the Token Ring network we need 132 hosts to connect. You need to take into account the gateway addresses that need to be allocated for each of the subnets. Assign IP addresses to hosts A, B, C and D and IP addresses to the router gateway interfaces.
