Differences between IPV4 and IPV6

IPv4	IPv6
1.IPv4 addresses are 32 bit length.	1.  IPv6 addresses are 128 bit length.
2.IPv4 addresses binary numbers represented in decimals.	2.  IPv6 addresses binary numbers represented in hexadecimals.
3.IPSec support is only optional.	3.  Inbuilt IPSec support.
4.Fragmentation is done by sender and forwarding routers.	4.  Fragmentation is done only by sender.
5.No packet flow identification.	5.  Packet flow identification is available within the IPv6 header using the Flow Label field.
6.Checksum field is available in IPv4 header	6.  No checksum field in IPv6 header.
7.Options fields are available in IPv4 header.	7.  No option fields, but IPv6 Extension headers are available.
8.Address Resolution Protocol (ARP) is available to map IPv4 addresses to MAC addresses.	8.  Address Resolution Protocol (ARP) is replaced with Neighbor Discovery Protocol.
9.Internet Group Management Protocol (IGMP) is used to manage multicast group membership.	9.  IGMP is replaced with Multicast Listener Discovery (MLD) messages.
10.            Broadcast messages are available.	10.              Broadcast messages are not available. Instead a link-local scope all-nodes multicast address is used for broadcast.
11.            Manual configuration (Static) of IPv4 addresses or DHCP (Dynamic configuration) is required to configure IPv4 addresses.	11.              Auto-configuration of addresses is available.
