Abstract: A network device may receive IPv6 fragments of a flow. Source and/or destination port information may be encoded into an upper sixteen bits of an identification number of an IPv6 fragment header of each of the IPv6 fragments. The network device may extract the source and/or destination port information from the IPv6 fragments, and may perform a spoof check of the IPv6 fragments. The network device may drop any of the IPv6 fragments that fail the spoof check, to generate remaining IPv6 fragments, and may translate the remaining IPv6 fragments into IPv4 fragments based on the source and/or destination port information. The network device may forward the IPv4 fragments toward an IPv4 cloud network.
