SIIT-DC (RFC7755) and SIIT-DC Dual Translation Mode (RFC7756) specify extensions to the Stateless IP/ICMP Translation Algorithm (SIIT) to accommodate DC deployment contexts, in particular. These two RFCs specify the behavior of two elements (SIIT-DC Border Relay (BR), SIIT-DC Edge Relay (ER)). The specifications not only provide operational guidance, but also specify normative implementation functions that are essential to ensure interoperability and deterministic behavior, so that IP communications are successfully established.

The SIIT extensions specified in RFC7755 and RFC7756 are widely accepted, implemented [1][2], and deployed. Thus, operational experience supports this reclassification from Informational to Proposed Standard.

Consistent with its Charter [3], V6OPS WG requests the reclassification of these two RFCs to Proposed Standard.
