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
The graphs below show the relative performance (over 10 minute intervals) between IPv4 and IPv6 RTT "distances", as seen by our vantage points. A value on the upper/positive side of the axis means that the IPv6 connectivity is performing better than the IPv4 and is marked in green, whereas the lower/negative values marked in blue represent that the IPv4 connection is better (from the particular vantage point, or set of vantage points). See below for exact averaging methodology.

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.
