This document discusses measurements of IPv6 deployment in Finland. It finds that while IPv6 readiness among internet infrastructure organizations in Finland is high, actual end-user IPv6 usage was only around 4% until recently, when one major Finnish ISP increased their IPv6 customers to 11%. IPv6 performance measurements show IPv6 is sometimes faster but usually on par with IPv4, suggesting dual-stack networks can take advantage of both protocols for optimal performance. In conclusion, Finland is beginning to deploy IPv6 more broadly but significant latent IPv6 capacity remains among infrastructure and end-users.

Is IPv6 Faster? Sometimes!
• Dual-stack user:
- Two chances for the best performance
- In 12%-18% of cases can be significantly faster than the
IPv4-only user
- “Happy Eyeballs” implementations can facilitate this
- Important for latency-sensitive applications
• VOIP
• Gaming
