IPv4 and IPv6 are internet protocol version 4 and internet protocol version 6, IP version 6 is the new version of Internet Protocol, which is way better than IP version 4 in terms of complexity and efficiency.
Difference Between IPv4 and IPv6:
|IPv4 has 32-bit address length||IPv6 has 128-bit address length|
|It Supports Manual and DHCP address configuration||It supports Auto and renumbering address configuration|
|In IPv4 end to end connection integrity is Unachievable||In IPv6 end to end connection integrity is Achievable|
|It can generate 4.29×109 address space||Address space of IPv6 is quite large it can produce 3.4×1038 address space|
|Security feature is dependent on application||IPSEC is inbuilt security feature in the IPv6 protocol|
|Address representation of IPv4 in decimal||Address Representation of IPv6 is in hexadecimal|
|Fragmentation performed by Sender and forwarding routers||In IPv6 fragmentation performed only by sender|
|In IPv4 Packet flow identification is not available||In IPv6 packetflow identification are Available and uses flow label field in the header|
|In IPv4 checksumfield is available||In IPv6 checksumfield is not available|
|It has broadcast Message Transmission Scheme||In IPv6 multicast and any cast message transmission scheme is available|
|In IPv4 Encryption and Authentication facility not provided||In IPv6 Encryption and Authentication are provided|
