Question

1. Consider sending a 4000-byte datagram into a link that has an MTU of 500 bytes. Suppose the original datagram is stamped with the identification number 526. How many fragments are generated? What are their characteristics? Please show work (Assume IPv4 is used so the IP header is 20 bytes in length);2. A datagram network uses a 16-bit host addresses. Assume a router uses longest prefix matching and has the following forwarding table;-----------------------------------------------;Prefix Match Interface;-----------------------------------------------;1 0;11 1;111 2;Otherwise 3;Give the associated range of destination host addresses for each of the four interfaces and the number of addresses in the range. Please provide solution similar to the following 8-bit table;8-bit;Prefix Min Number Max Number Range;1 1 0000000 = 128 1 0111111 = 191 64 = 2 6;11 11 000000 = 192 11 011111 = 224 32 = 2 5;111 111 00000 = 224 111 11111 = 255 32 = 2 5;Otherwise 0 0000000 = 0 0 1111111 = 127 128 = 2 7
