This week we covered addressing scheme in TCP/IP. A major part of that being the creation of private IP addresses. What is the reason behind private IP addresses?

Solution

The private IP address are the address of machines which are not directly connected to internet. Usually, there will be multiple computers which share an internet connection within a network/organization. Here, all the computers within that network/organization share the same IP address with reference to the outside world. But with reference to within the network, to differentiate the computers from one another, every machine will be assigned a unique IP address,and this addresses are called private IP addresses.

The private addresses are within the range:

192.168.0.0 - 192.168.255.255 (65,536 IP addresses). This is a 16-bit block.

172.16.0.0 - 172.31.255.255 (1,048,576 IP addresses). This is a 20-bit block.

10.0.0.0 - 10.255.255.255 (16,777,216 IP addresses). This is a 24-bit block.
