IETF 125: IPv6 over Networks of Resource-Constrained Nodes (6LO) 2026-03-20 03:30

Why It Matters

Progress toward publication and clearer scope for GA/PASA streamlines IPv6 addressing in resource-constrained networks, enabling more interoperable, single-hop address assignment for IoT deployments; obsoleting RFC 8163 and updates to transmission drafts affect implementers and vendors planning 6Lo deployments.

Summary

At IETF 125 the 6Lo (SISLO) working group met remotely to review agenda items and document statuses. Chairs reported two newly published RFCs (9926 and 9927) and five active working-group drafts, with the PASA and GA drafts advanced and publication requested pending AD review. GA was revised to clarify scope and algorithmic address-assignment use cases in response to sixman comments, emphasizing one-hop operation and alignment with RFC 8505; PASA remains a specific application of GA. Other drafts include updates for 6LoWPAN transmission over 802.15.4, short-range optical links, and a draft intended to obsolete RFC 8163.
