What is IP (Internet Protocol)?
Internet Protocol is used to specify the technical format of packets and the addressing scheme for the computers,laptops in the internet. It is working in the network layer of OSI reference model.
The different versions of IP’s are present : IPv4 and IPv6.
The difference between these two are given below:
| IPv4 | IPv6 |
IPv4 represents 32-bit address length | IPv6 represents 128-bit address length |
| It Supports Manual and DHCP address configuration for the network | It supports Auto and renumbering address configuration for the network. |
| In IPv4 end to end connection integrity is cannot be achievable | In IPv6 end to end connection integrity can be Achievable |
| It can generate 4.29×109 address space | Address space of IPv6 is quite large it can produce 3.4×1038 address space |
| Address representation of IPv4 in decimal. | Address Representation of IPv6 is in hexadecimal. |
| Fragmentation carried out by Sender and forwarding routers | In IPv6 fragmentation carried out only by sender |
| In IPv4 checksum field is present | In IPv6 checksum field is not present |
| IPv4 has header of 20 bytes. | IPv6 has header of 40 bytes fixed |
| It has broadcast Message Transmission Scheme | In IPv6 multicast and any cast message transmission scheme is present |
| Example : 192.16.8.9 | Example : 1234:5678:9abc:def0 |
