A network device may receive, from a source device, an option request that includes a source address of the source device and a destination address of a destination device, wherein the network device is associated with an Internet protocol version 6 (IPv6) network. The network device may identify a map code that is associated with an address translation for traffic associated with the destination device and may determine, based on identifying the map code, a source prefix code and a destination prefix code for the address translation. The network device may determine a source IPv6 prefix and a destination IPv6 prefix for the address translation based on the source prefix code and the destination prefix code and may provide, to the source device, an option response to the option request to permit the source device to use the source IPv6 prefix and the destination IPv6 prefix for the traffic.
