+# RFC 015 – Mandatory IPv6 Adoption
+
+## Summary
+
+All IBP members must provide IPv6 addresses for their endpoints by January 31,
+2026.
+
+## Motivation
+
+JAM is an IPv6-only network planned for launch Q3 2026. IBP proxies must support
+IPv6 by Q1 2026 to be JAM-ready.
+
+## Why All Members
+
+AAAA records override A records in DNS resolution. If only partial members
+provide IPv6 addresses, GeoDNS will route to the reduced set of IPv6-capable
+endpoints. This degrades latency and coverage for all users as fewer geographic
+endpoints are available.
+
+100% member adoption is required to maintain current service quality when IPv6
+is enabled.
+
+## Proposal
+
+| Requirement | Deadline |
+|---|---|
+| All members submit IPv6 addresses to config | January 31, 2026 |
+| IPv6 endpoints operational and reachable | January 31, 2026 |
+
+Members not compliant by deadline become ineligible for bandwidth reimbursement
+at RFC-014 rates until compliant.
+
+## Rationale
+
+JAM's IPv6-only architecture requires IBP infrastructure to be fully
+IPv6-capable before launch. Q1 2026 compliance gives 6 months buffer before Q3
+2026 JAM launch for testing and integration.
