Question 433 Explanation:
→Given address is CIDR network address 210.32.64.79/26.
→Classless addressing treats the IP address as a 32 bit stream of ones and zeroes, where the boundary between network and host portions can fall anywhere between bit 0 and bit 31.Classless addressing system is also known as CIDR(Classless Inter-Domain Routing).
→The first address in the block can be found by setting the rightmost 32 − n bits to 0s.
→The last address in the block can be found by setting the rightmost 32 − n bits to 1s.
→The number of addresses in the block can be found by using the formula 232−n.
→Here “n” is 26.
→Classless addressing treats the IP address as a 32 bit stream of ones and zeroes, where the boundary between network and host portions can fall anywhere between bit 0 and bit 31.Classless addressing system is also known as CIDR(Classless Inter-Domain Routing).
