Revision as of 01:52, 10 June 2010
I may not have understood the yum method correctly, but as far as I can tell, the IPs are only unique per release version. I.e. if I install F12 on a system with a static IP, do updates, then wipe it and install F13 instead and do updates to that, my IP gets counted as unique in both the F12 and the F13 number. Thus the total across releases is not really the number of unique IPs.
Jef Spaleta estimated the total number of Fedora clients to be 16 million in May 2009. If the non-smolt-corrected number is now 22 million, Fedora has had a nearly 40 % increase in installed base over the past year. That doesn't seem quite realistic. --mhuhtala 2010-06-08
- The sum of IP addresses at the right of that chart could be misleading, and I've been considering dropping it. However, the total IP address count is unique across all releases. So the case you mention above would not be counted twice in that number. --pfrields 14:52, 8 June 2010 (UTC)
