- IP Stands for Internet Protocol.
- IP address means each and every system have unique IP address.Which is used to identify the system over network and for communicating with other systems.
Format of an IP address :
- The format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be zero to 255.
- 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 :
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.
