TM Unifi IPv6 prefix, changed from /56 to /64
Posted: Mon Oct 19, 2026 7:42 pm
Hello,
I see you have some experience with IPv6 with TM Unifi. I have a business plan. They used to give me /56 prefix for many years. However, recently (I think 1-2 months ago), I detected that some of my VLANs are no longer on IPv6. When I checked, TM changed the PD from /56 to /64, which means I cannot subnet them.
Do you have experience with TM-Unifi, whether requesting a larger prefix is OK?
I am now using NPT6 (on OpenWRT), which is not ideal. I tried to contact TM-Unifi, but I may need to reset the PIC information, as this is a company account.
Thanks!
