However, DNS implementations are already required to support both TCP and UDP, and using TCP would alleviate these considerations. This document specifies that new protocols with a dependency on Classic DNS do not need to account for the limitations of Classic DNS over UDP and can instead expect implementations to use Classic DNS over TCP.}, }
