  • For example, 2.10.130.250 could be an IP address. 

Static vs Dynamic IP address :

Static IP address
Dynamic IP address
Static IP address means it will not change as long as you stay with the same provider or same services. Dynamic IP address means it will vary each and every time  network.
Static IP address is more expensive. Dynamic IP address is less expensive
Static IP address need additional security. Dynamic IP address provides high security.Because changing IP address gives more privacy.
Static IP address will provided by ISP Dynamic IP address will provided by DHCP
Easily traceable by hackers Impossible to tracing.Because,each and every time IP address is vary.


How we know the IP address of our system :

  • Open the Command Prompt.

  • Type the 'ipconfig' and then press Enter button.

Types of the IP address :

IPv4 Address :
  • IP addresses have two common formats. IP version 4 addresses are comprised of four numbers-only segments separated by dots:
      • e.g. 127.0.0.1
      • e.g. 253.16.44.22
      • e.g. 72.48.108.101
  • IPv4 address is classified into 5 types of classes.
  • Those are Following :

Class Start address Finish address
A 0.0.0.0 126.255.255.255
B 128.0.0.0 191.255.255.255
C 192.0.0.0 223.255.255.255
D 224.0.0.0 239.255.255.255
E 240.0.0.0 255.255.255.255


IPv6 Address :
  • IP version 6 addresses are more complex. IPv6 address are comprised of 8 segments:
      • e.g. 3ffe : 1900 : 4545 : 3 : 200 : f8ff : fe21 : 67cf
      • e.g. 21DA : D3 : 0 : 2F3B : 2AA : FF : FE28 : 9C5A

Advantages of IP address :

  • IP address will be used to Identify the particular system.
  • IP address is also used at the time of file transferring over the network.
