RIPE NCC - World IPv6 Day Measurements - ping (RTT) measurements
The following graphs show how our measurement vantage points see the individual IPv6 day participants or other destinations. Below you can select:
- the measured destination
- the target: each measured destination has a measured main site (usually www), and may also have a dual-stack site available
- source region
as of 2014-04-21 12:49:30 UTC, target: primary site

Methodology details: For averaging the relative RTT (IPv4/IPv6) over multiple source:destination pairs, we use this formula:
avg = 2^( ( log2( v4_a/v6_a ) + log( v4_b/v6_b ) ... ) / n )where '_a','_b',... are different source:destination pairs and n is the number of source:destination pairs. This is a form of the geometric mean. For displaying the value on the graph convert this into a percentage form, for instance, if the average is 0.5 this means IPv4 is 2x as fast, so IPv4 performance is +100% of IPv6 performance. If the average is 2 this means IPv6 is 2x as fast as IPv4, so IPv6 performance is +100% of IPv4 performance.
