What are IPv4 Address
IPv4 Addresses are the combination of numbers used on the internet to transfer user data from source to destination and the range of the IPv4 Addresses Numbers are between 0-255 only.
IPv4 Addresses are 32-bit addresses divided into 4 parts which are known as octets and bits are the combinations of 0 & 1 only.
Classes of IPv4 Address
IPv4 addresses are divided into 5 classes based on the Priority Bits.
Priority bit is used for IP address Classification.
The most significant bit(s) from the first octet are selected for Priority bit(s).
|Class B||128 – 191||10|
Note: In Class A 127 is reserved as Loopback Address.
Types of IPv4 Addresses
There are certain addresses in each class of IP Addresses that are reserved for Private Networks. These addresses are called private Addresses.
The Private addresses are not Routable (or) Not Valid on the Internet.
|Class||Private IP Address Range|
|Class A||10.0.0.0 to 10.255.255.255|
|Class B||172.16.0.0 to 172.31.255.255|
|Class C||192.168.0.0 to 192.168.255.255|
Number of Network / Host Class wise
|Class||No of Networks||No of Host|
The difference between Public & Private IPv4 Addresses
|Public IP Address||Private IP Address|
|Used on the Internet||Used within the Organization|
|It should be unique over the internet||It should be unique within the LAN or Organization|
|Assigned by the Internet Service Provider||Assigned by Network Administrator|
|Need to Purchased from Internet Service Provider.||Free|
