Abstract: Systems and methods are described for communications between computing devices via a stateless high-volume network address translation (“NAT”) service. The stateless high-volume NAT service manages high volumes of connections between networks by encoding at least part of the information needed to manage a connection in an encoded IPv6 address, which is then used by a NAT device or application as its sending address when relaying data from a source to a destination. The encoded IPv6 address may contain information such as the IPv4 address of the source, the IPv4 address of the destination, the protocol used to communicate, the source and destination ports, and the like. When the destination sends a response to the encoded IPv6 address, the NAT device decodes the IPv6 address to obtain the encoded information, and then uses that information to deliver the response to the source.
