1. IP addressing. a. Write the IP address 129.17.129.97 in its binary form. b. Consider an IP subnet with prefix 129.17.129.97/27. Provide the range of IP addresses (of form xxx.xxx.xxx.xxx to yyy.yyy.yyy.yyy) that can be assigned to this subnet Suppose an organization owns the block of addresses of the form 297.129.97/27. Suppose it wants to create four IP subnets from this block, with each block having the same number of IP addresses. What are the prefixes (of form xxx.xxx.xxx/y) for the four IP subnets? c. 2. Longest prefix matching. Consider a datagram network using 32-bit host addresses. Suppose that a router has three interfaces, numbered 0 through 2 and that packets are to be forwarded to these link interfaces as follows. Any address not within the ranges in the table below should not be forwarded to an outgoing link interface. Create a forwarding table using longest prefix matching Destination address range Outgoing link interfoce through 01010101 00000000 00000000 00000000 through 01010110 00000000 00000000 00000000 through
