- IPv6 has been properly implemented in cPanel/WHM, enabling dual-stack hosting without complex workarounds.
- Previous limitations included SNI not being usable with shared IPv6 addresses and requiring separate prefixes for servers and websites.
- The Network Crew Pty Ltd (TNC) worked with APNIC’s Technical Assistance Platform (TAP) to resolve IPv6 deployment issues.
- Key problems included RouterOS v7 routing oddities and cPanel/WHM’s IPv6 implementation.
- TNC collaborated with cPanel developers to remove IPv6 overlap restrictions and resolve legacy warnings.
- Changes were tested in development builds and later promoted to stable and LTS releases.
- TNC deployed AAAA records and /96 prefixes for smooth dual-stack implementation.
- Internal network resilience was improved with BGP and VRRP for both IPv4 and IPv6.
- APNIC TAP’s support was instrumental in achieving network overhaul and IPv6 deployment.
- The successful IPv6 deployment contributes to the APNIC region crossing the 50% IPv6 adoption milestone.
