What is IP Address

Address are use for identification. It is like name of person.
 computer is using two types of address
    IP ADRESS and MAC ADDRESS.

MAC ADDRESS:

MAC (media controller address) is LAN address , Which use for identify data in to the LAN.
 It is work on layer 2.
 It is 48 bit hexadecimal.
Switch can understand MAC address.
It is use for system identification.
It is permanent   .

For check IP add start- run –cmd – ipconfig  /all



It is also known as physical add , Ethernet add , LAN address , NIC address .

It is stored in LAN card.





In computer world an ip is

    0.0.0.0   first ip

    255.255.255.255  last ip

Why first ip is 0.0.0.0 ?

0 is a off bit.

1 is a on bit.
00000000.00000000.00000000.00000000     All off




    

 0             0             0             0   
11111111.11111111.11111111.11111111   All on



    255          255         255          255
How many ip add in the world ?


žNow a days all ip address are finished , so IANA(Internet Assigned Numbers Authority) makes second generation of ip address.

   1) ipv4

          Ipv4 have 32 bits.

   2) ipv6

          Ipv6 have 128 bits.

Supernet

Supernet Supernet is used for to merge multiple route into single router. Supernet is create max.7 network Supernet is covered in into small size network Supernet create in 4 step’s 1. First convert all ip into binary 2. Now set the end operation end operation condition’s. operation are       a. all bit is one then output is one       b. all bit is zero then output is zero       c. if one bit is one and second is zero then output will zero 3. After set end operation now create new ip 4.Count common bit and create subnet mask For example                       172.16.111.0                       172.16.112.0                       172.16.113.0  1. Now convert it into binary.       10101100         00010000              01101111        00000000 10101100         00010000              01110000        00000000 10101100         00010000              01110001        00000000 2. Now set the end operation end operation condition’s and create new ip  10101100         00010000               01101111
