IPv6 Vs IPv4 | IPv6 Comparison with IPv4

differences IPv6

Difference between IPv4 and IPv6:

Following are the some key features of IPv4 and IPv6 address, with these features you can compare these two version of internet protocols.

  • We have the extended address space in IPv6, IPv4 is of 32 bits and IPv6 is of 128 bits
  • Ipv6 addresses are globally unique.
  • Fixed header length: in IPv4 you have the fixed header where as in IPv6 you have the option headers that you can use for different purposes.
  • Ipv6 offers the address auto configuration without any DHCP, where as in IPv4 you need to have a DHCP for assigning dynamic IPv4 addresses.
  • You can have the support for labeling traffic flows.
  • You have some build-in security features in IPv6 like IPSEC and AH.
  • IPV6 provide the site multi-homing, you can multi-home host and address with multiple IP prefix which allow you to connect with multiple ISPs.
