Abstract
A method of receiving a data packet from an IPv4 domain in an IPv6 domain, the data packet comprising an IPv4 destination address and a destination port number. The method comprises the following steps: constructing an IPv6 destination address by concatenating an operator prefix, the IPv4 destination address, and the destination port number; generating an IPv6 data packet from the IPv6 constructed destination address and the received IPv4 data packet; and routing the generated IPv6 data packet in the IPv6 domain using the IPv6 constructed destination address, the constructed address belonging to a range of IPv6 addresses routable to an interconnection equipment of the IPv6 domain with the IPv4 destination address.
