10/21 Anyone know of a study where I can find the frequency of usage
of RFC1918 networks? I.e. how many people use 10.x, 172.16.x,
192.168.x, etc? -John
\_ Doubt you can find a reliable number. Since these networks are
private, people don't usually notify anyone else (outside their
organizations) about their topology...
\_ Don't need anything reliable, just general trends and
preferences (such as, based on personal experience, more
manufacturers use 192.168.{0,1}.0/24 as default nets than
172.16.0.0--was wondering if there were any surveys around.
\_ Try doin it in reverse. You could probably find stats on
the number of publicly accessible IPs. Then find stats on how
many computers are connected to the internet (also a number
you can get estimates on). Go from there...
\_ One thing you can get a vague number on is the number of
reverse-resolution requests for RFC1918 networks. Those *still*
go to central dns servers on many poorly configured networks.
It caused enough DNS load that they went to an anycast architecture
to decentralize the DNS load.
\_ Who are the "they" you are referring to? I'm helping
run/implement anycast DNS for a number of ccTLD's as well as one
of the root servers. I know of a few other organizations that
have proposed anycasting their DNS, but was not aware of any
that were actually doing implementation work. It would be cool
to have others working on the same problem to bounce ideas off
of. -dans |
