- IPv4: of the 728 hosts measured 50% have average(RTTs) within 2.15ms of one another. The hosts are in 160 different countries with China having the most hosts with 195, follwed followed by the United States with 52, Indonesia with 37, Malaysia with 27 and Pakistan with 13. In terms of regions the top region is East Asia with 206 hosts, 101 from Africa, 63 from Europe and 58 from North Amerca (Canada and the United States). There are 593 host that have 'www' in the name. The range of average ping RTTs is from 0.327ms to 377ms. The range of nping RTTs is from 2.3ms to 387ms.
Another way of looking at the data is to consider the relative differences, i.e. (Avg(ping_RTT)-Avg(nping_RTT)/(0.5(Avg(ping_rtt)+Avg(nping_RTT)), this gives the distribution below that shows the IQR of the averge difference is ~ 1.2%. If one looks at the hosts that have relative differences of > 22% or less than -22% (about 2% of the hosts), we find most are from China or have low RTTs (< 4 msec).
- IPv6: 50% of the 36 hosts measured have average(RTTs) within 0.26ms of oneanother).
Again the relative ping vs nping differences for IPv6 is shown below and shows an IQR of the relative average difference is 0.45%:
