IP Address Study of the basics.

Dear Readers,
Here are some important points and facts about the IP (Internet Protocol). 

The IP (Internet Protocol) is basically an address that identifies the connection of a host to its network.
The IPv4 address consists of 4 bytes (i.e. 32 bits). It has 3 field part :  Type , Netid, Hostid.
Depending on the length of the fields the IPs are classified into 5 Classes. Which are, Class A, ClassB, Class C, Class D, Class E.
The Dotted-Decimal Notation:
The IPv4 addresses are usually written in a decimal form with decimal points separating the 4 bytes (as mentioned earlier). Eg: .

IPv4 & IPv6 :
The most commonly used version of the protocol is IPv4. With the increasing growth of Internet,  the IPv4 faces some deficiencies. IPv6 was proposed and is now the new standard.
The IPv6 gives the following advantages over IPv4.
1.      Larger address space.
2.      Better Format.
3.      Allowance of extension.
4.      Support for resource allocation.
5.      More secure transmission.

The Hexadecimal Colon Notation. :
As IPv4 uses the Dotted Decimal Notation, the IPv6 uses the Hexadecimal Colon Notation. The Colon separates the 128 bit address into 8 segment. Eg. FE80 : F5AD : 3198 : ACCF : ADFB : 3210 : FFFF : FDCA .
