The '''Transport Relay Translation''' ('''TRT''') method acts as an intermediate device between two hosts. The function of the translator is to convert IPV6 into IPV4 addresses and vice versa. TRT accomplishes this translation through IP address mapping and a custom IP address.{{Ref RFC|3142}}

The address, for example, if packets are to be transmitted from an IPv6 address ({{IPaddr|fec0:0:0:1::|64}}) to an IPv4 address ({{IPaddr|10.1.1.1}}) would read as {{IPaddr|fec0:0:0:1::10.1.1.1}}. The packets are routed towardstoward the translator firstly through an IPv6/TCP protocol and then from the translator to the IPv4 host through an IPv4/TCP protocol.<ref>{{cite web |last1=Shanmugaraja |first1=P. |title=Design and Implementation of Transport Relay Translator and its security Mitigations |url=https://www.researchgate.net/publication/290350020 |website=researchgate.net |publisher=Research Gate |access-date=28 June 2024}}</ref>

TRT employs a similar operation to DNS translation between AAAA and A records known as ''[[DNS ALG]]''.{{Ref RFC|2694}}
