Differences between IPv4 and IPv6
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 | 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 is 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 |
| IPv4 has header of 20-60 bytes. | IPv6 has header of 40 bytes fixed |
