Differences IPv4 Vs IPv6

Differences IPv4 Vs IPv6

I had compiled differences between IPv6 and IPv4 long back. Though it is for my personal reference I am uploading it on my blog. Hope someone might find this useful.
Thanks to those known and known sources who helped me compile this.
IPv4
IPv6
Addresses are 32 bits (4 bytes) in length. Addresses are 128 bits (16 bytes) in length
Address (A) resource records in DNS to map host names to IPv4 addresses. Address (AAAA) resource records in DNS to map host names to IPv6 addresses.
Pointer (PTR) resource records in the IN-ADDR.ARPA DNS domain to map IPv4 addresses to host names. Pointer (PTR) resource records in the IP6.ARPA DNS domain to map IPv6 addresses to host names.
IPSec is optional and should be supported externally IPSec support is not optional
Header does not identify packet flow for QoS handling by routers Header contains Flow Label field, which Identifies packet flow for QoS handling by router.
Both routers and the sending host fragment packets. Routers do not support packet fragmentation. Sending host fragments packets
Header includes a checksum. Header does not include a checksum.
Header includes options. Optional data is supported as extension headers.
ARP uses broadcast ARP request to resolve IP to MAC/Hardware address. Multicast Neighbor Solicitation messages resolve IP addresses to MAC addresses.
Internet Group Management Protocol (IGMP) manages membership in local subnet groups. Multicast Listener Discovery (MLD) messages manage membership in local subnet groups.
Broadcast addresses are used to send traffic to all nodes on a subnet. IPv6 uses a link-local scope all-nodes multicast address.
Configured either manually or through DHCP. Does not require manual configuration or DHCP.
Must support a 576-byte packet size (possibly fragmented). Must support a 1280-byte packet size (without fragmentation).
Network Sorcery is a great place to find RFC(s).
Refer to http://www.networksorcery.com/enp/protocol/ipv6.htm and http://www.networksorcery.com/enp/protocol/ip.htm links for related RFC(s) of IPv6 and IPv4 respectively.
Also there is good reference for Understanding IPv6 @ http://technet.microsoft.com/en-us/library/cc786127.aspx
