The way blocks are used by the RIRs means that /8 sized networks* are
more often than not used in a single region. Other than legacy
registrations, there are 5 RIRs that assign IPs, ARIN (North America),
LCANIC (South America), AFNIC (Africa), APNIC (Asian Pacific, includes
AU and NZ) and RIPE (Europe).
If all you have is an IP, then ordering the list by the first octet
makes sense for the /8 you are in. It doesn't really do well beyond
that boundry. After that all best are off. However, it is better than
basing the order off the last octet, which means nothing.
In the other message a few netblocks were picked on. 62/8, 81/8, 82/8,
83/8 213/8 and 217/8 are all RIPE IP ranges. Perhaps there is not the
raw volume of players in RIPE land so, they simply have less
population. Or perhaps the data does not take into account the
difference of time zones, and was looking at servers in the US on their
peak times, and servers in the EU at their off times. It's hard to
tell since no data collection methodolgy was given. The numbers could
be completly random for all we know.
41/8 Is reserved and not in use. Not sure where data from that bogon
block came from. 61/8, 210/8, 211/8 are all APNIC space. 128/8 is
given out to schools IIRC. I know the U of MN has 128.101/16.
Based only on a server's IP address you can't really tell much about
the server itself. There is nothing about an octet of the server's IP
address that makes it good or bad, but thinking makes it so.
* /8 is CIDR for what used to be called a Class A (pretty much).
24.0.0.0/8 is the range of 24.0.0.0 to 24.255.255.255, or all
IPs with a first octet of 24.
