Dual-stack is now the default. Pure IPv6 + DS-Lite for new fiber drops in 2025.
Why it matters
IPv6 is the easy part. We have been dual-stack for years and as of this summer every residential customer has a real IPv6 prefix.
The hard part is the transition mechanisms. CGNAT on cable is a workaround, not a solution. We will continue to offer free public IPv4 on request, and our long-term plan is IPv6 + DS-Lite for new fiber drops.
What we are doing
This is the kind of thing we like to talk about publicly. Where we are early, we share the math. Where we are wrong, we say so. We would rather customers trust us to communicate honestly than wish away every problem.
"The best way to be trusted is to be trustworthy in small things first." — engineering team motto
