    This contribution proposes targeted edits to IPNNI-2026-00012R005 to clarify that ALIII public-Internet interconnection should not be the sole available means of reaching numbering resources made reachable through the ALIII framework. The proposed edits add a requirement that code holders maintain an alternative off-Internet interconnection path, such as direct cross-connect or equivalent private interconnection fabric at carrier-neutral facilities, and clarify that mTLS/certificates authenticate approved peers but do not by themselves mitigate public-Internet availability risks such as volumetric DDoS, TLS/SIP state exhaustion, DNS attacks, or upstream congestion.
