I just need help with the last question with stars.
IP Addresses are stored as binary numbers in four 8-bit bytes (strings of 0’s and 1’s). For ease of reading, these are translated into their four equivalent decimal numbers, separated by dots, to form “dot separated decimals.” Use the facts given about binary numbers, along with the multiplication principle, to answer the following questions about IP addresses:
What is the decimal value of the binary number 10101011? (Note that this is the same number shown in the place-value table below.
How many different decimal values are possible for an 8-bit binary number?
********How many different IP addresses can be stored as described above?**********
Explanation / Answer
An IP address which belongs to class B has the first two bits in the first octet set to 10, i.e.
10000 000-10111111
128-191
Class B IP Addresses range from 128.0.x.x to 191.255.x.x.
SO FOR 10101011 =171 IS ALSO UNDER CLASS B
Class B has 16384 (214) Network addresses and 65534 (216-2) Host addresses.
