Frequently Asked Questions
Q. Why is IPv6 adoption only ~40%?
Large legacy infrastructure still runs on IPv4 with NAT. Transitioning requires significant dual-stack deployment costs for both ISPs and hardware.
Q. Is IPv6 faster than IPv4?
Not inherently. However, in congested NAT environments, IPv6 can feel faster because it avoids address translation overhead.
Q. Do I need IPv6 at home?
It's not critical yet as most sites still support IPv4, but as IPv4 addresses run out, IPv6 will become the mandatory standard.
Q. Can I have an IPv6-only connection?
Possible, but many legacy services are IPv4-only. Dual-stack is currently the practical standard for full connectivity.
Q. How do I enable IPv6?
Check your router admin panel under WAN settings. Enable IPv6 if your ISP supports it.
