Internet Protocol (IP) Address

 

IP ADDRESS

IT IS A UNIQUE ADDRESS THAT WE CAN ASSIGN TO DEVICE .SO THAT DEVICECAN COMMUNICATE WITH EACH OTHER.

WE CANNAOT ASSIGN SAME IP ADDRESS IN ANY TWO DEVICES IN OUR NETWORK. IF WE WILL DO THIS THEN IT WILL BE  CAUSE A CONFLICT ERROR.

TWO VERSION OF IP ADDRESS: 1: IPV4 ; 2: IPV6 ; IPV4 32 BITS AND IPV6 128 BITS.

AN IP ADDRESS, OR INTERNET PROTOCOL ADDRESS, IS A SERIES OF NUMBERS THAT IDENTIFIES ANY DEVICE ON A NETWORK. 

COMPUTERS USE IP ADDRESSES TO COMMUNICATE WITH EACH OTHER BOTH OVER THE INTERNET AS WELL AS ON OTHER NETWORKS.

TO FIND THE IP ADDRESS CLASS WE NEED TO LOOK AT THE FIRST DIGIT OF THE IP ADDRESS.

AND BY LOOKING AT THE FIRST DIGIT, WE CAN GUESS THE SUBNET MASK TO WHICH CLASS IT BELONGS.

CLASS A IP ADDRESS SUBNET MASK 255.0.0.0

CLASS B IP ADDRESS SUBNET MASK  255.255.0.0 

CLASS C IP ADDRESS SUBNET MASK 255.255.255.0

IANA TABLE IP RANGES

                IANA  ( Internet Assigned Numbers Authority)

Class	Address Range	USES
IP Class A	1 to 126	Used for large number of hosts.
IP Class B	128 to 191	Used for medium size network.
IP Class C	192 to 223	Used for local area network.
IP Class D	224 to 239	Reserve for multi-tasking.

TYPES OF IP ADDRESS

Static And Dynamic Ip Address

PUBLIC AND PRIVATE IP ADDRESS

_____________________________

IP ADDRESSING

N IS REPRESENTED  NETWORK AND RESOLVED FOR NETWORK AND H REPRESENT HOST AND RESOLVED FOR HOST.

FOR EXAMPLE : CLASS A IP ADDRESS IS 15.1.1.1 AND 15 IS NETWORK IP AND 1.1.1 IS HOST DEFINED.

CLASS B IP IS 172.165.5.1 AND 172.165 IS NETWORK IP AND 5.1 IS HOST DEFINED.

CLASS C IP ADDRESS IS 192.168.6.10 AND NETWORK IP IS 192.168.6 AND 10 IS HOST DEFINED.

IF YOU WANT TO CREATE A LOCAL AREA NETWORK, YOU WILL FIRST NEED TO PURCHASE A PUBLIC IP ADDRESS. 

AFTER THAT, WHEN YOU HAVE TO ASSIGN AN IP ADDRESS TO A DIFFERENT DEVICE, YOU NEED TO KEEP THE NETWORK ADDRESS SAME OF THE IP ADDRESS YOU PURCHASED FROM YOUR PUBLIC IP ADDRESS AND CHANGE ITS HOST ADDRESS AND ASSIGN DIFFERENT DEVICES.

CLASS C IP ADDRESS

DID YOU SEE THAT THE PUBLIC IP ADDRESS BELONGS TO THE CLASS C AND THE   CLASS C ARE FOR THE  FIRST 3 DIGIT DIGITAL NETWORK  RESOLVED OF THE  AND THE LAST DIGIT IS THE HOST RESOLVED AND YOU SAW THAT WHEN WE ARE PROVIDING THE ADDRESS TO EVERYONE. 

SO FROM  NETWORK DIGIT IS SAME BUT HOST DIGIT IS CHANGED.

CLASS A IP ADDRESS

SAME PROCESS IN CLASS B IP ADDRESS.

CLASS A 

FOR EXAMPLE CLASS A IP ADDRESS IS 10.1.1.1  AND WHAT WILL BE ITS NETWORK ID AND BROADCAST ID AND SUBNET MAST.

IP ADDRESS IS 10.1.1.1

BROADCAST ID IS  IP ADDRESS :  10.255.255.2555

NETWORK ID IS  IP ADDRESS :  10.0.0.0

SUBNETMASK  IS IP ADDRESS : 255.0.0.0

CLASS B

FOR EXAMPLE CLASS A IP ADDRESS IS 176.165.1.1  AND WHAT WILL BE ITS NETWORK ID AND BROADCAST ID AND SUBNET MAST.

IP ADDRESS IS 172.165.1.1

BROADCAST ID IS  IP ADDRESS :  172.165.255.2555

NETWORK ID IS  IP ADDRESS :  172.165.0.0

SUBNETMASK  IS IP ADDRESS : 255.255.0.0

CLASS C

FOR EXAMPLE CLASS A IP ADDRESS IS 196.168.3.1  AND WHAT WILL BE ITS NETWORK ID AND BROADCAST ID AND SUBNET MAST.

IP ADDRESS IS 196.168.3.1

BROADCAST ID IS  IP ADDRESS :  196.168.3.255

NETWORK ID IS  IP ADDRESS :  196.168.3.0

SUBNETMASK  IS IP ADDRESS : 255.255.255.0

USES OF IP ADDRESS

IP ADDRESS BLOCKING: 

IP ADDRESSES CAN BE BLOCKED TO PREVENT ACCESS TO CERTAIN WEBSITES OR SERVICES.

IP ADDRESS TRACKING:

IP ADDRESSES CAN BE TRACKED TO TRACK THE ONLINE ACTIVITY OF INDIVIDUALS OR GROUPS.

IDENTIFYING DEVICES ON A NETWORK: 

IP ADDRESSES ARE USED TO UNIQUELY IDENTIFY DEVICES ON A NETWORK. THIS ALLOWS DEVICES TO COMMUNICATE WITH EACH OTHER AND TO ACCESS RESOURCES ON THE NETWORK.

ROUTING TRAFFIC:

IP ADDRESSES ARE USED TO ROUTE TRAFFIC ON THE INTERNET. WHEN YOU VISIT A WEBSITE, YOUR COMPUTER'S IP ADDRESS IS USED TO FIND THE WEBSITE'S SERVER. THE SERVER'S IP ADDRESS IS THEN USED TO SEND THE WEBSITE'S CONTENT BACK TO YOUR COMPUTER.

SECURITY: 

IP ADDRESSES CAN BE USED FOR SECURITY PURPOSES. FOR EXAMPLE, THEY CAN BE USED TO BLOCK UNAUTHORIZED ACCESS TO A NETWORK OR TO TRACK DOWN HACKERS.

GEOLOCATION:

IP ADDRESSES CAN BE USED TO DETERMINE THE APPROXIMATE LOCATION OF A DEVICE. THIS CAN BE USEFUL FOR THINGS LIKE TARGETED ADVERTISING OR FRAUD DETECTION.

TROUBLESHOOTING: 

IP ADDRESSES CAN BE USED TO TROUBLESHOOT NETWORK PROBLEMS. FOR EXAMPLE, IF YOU'RE HAVING TROUBLE CONNECTING TO A WEBSITE, YOU CAN USE YOUR IP ADDRESS TO FIND OUT WHERE THE PROBLEM IS LOCATED.
