IPv4 addressing space is exhausted by the rapid growth of the Internet and the
devices connected to the Internet. IPv6 expands the IP addressing space by increasing the
address length from 32 bits to 128 bits.
10. What is the binary equivalent of the decimal number 232?
Each section (octet) contains eight binary digits. Each digit represents a specific
value (128, 64, 32, 16, 8, 4, 2, and 1). Everywhere there is a 1, the specific value is relevant. Add
all relevant values in a particular octet to obtain the decimal value. For example binary 11001011
equals 203 in decimal.
14. What is the decimal equivalent of the binary number 10010101?
0x refers to the item as hexadecimal. Convert each character into its corresponding
nibble. Then combine the nibbles together and calculate the resulting decimal equivalent. C has a
value of 12. 12 x 16 = 192. 192 + 9 = 201.
