What are the Key differences between IPv4 and IPv6. IPv4 Source and destination addresses are 32 bits (4 ytes) in length. IPsec header support is optional. No identification of packet flow for prioritized delivery handling by routers is present within the IPv4 header. Fragmentation is performed by the sending host and at routers, slowing router performance. Has no link-layer packet-size requirements and must be able to reassemble a 576-byte packet. Header includes a checksum. Header includes options. ARP uses broadcast ARP Request frames to resolve an IPv4 address to a link-layer address. Internet Group Management Protocol (IGMP) is used to manage local subnet group membership. ICMP Router Discovery is used to determine the IPv4 address of the best default gateway and is optional. Broadcast addresses are used to send traffic to all nodes on a subnet. Must be configured either manually or through DHCP for IPv4. Uses host address (A) resource records in the Domain Name S
