Ensure IPs generated are within 100.64/10 range. #3

Open colindean opened 8 years ago

100.64.0.0-100.127.0.0 are the valid IPs.

colindean commented 8 years ago

In commotiond, we just use the least significant octets of the MAC address, and then bitmask those based on whatever subnet gets handed to the IP generation function (which, even though it's 100.64.0.0/10 by default, could be anything). So we never generate an address outside of that subnet, because we start with the unique bits and then mask everything not in the subnet.

Correction. 100.64.0.0-100.127.255.255 are valid.

What Commotion does is a "modulo operation" so that the 4th segment of the MAC address is converted to fit within that range like so:

01=64, 02=65, 03=66 etc up until 39=127 Once the MAC segment=40 (64 in decimal), the IP address becomes 1 again.

Example: DC:9F:DB:39:05:A8 = 100.127.0.0 and DC:9F:DB:40:05:A8 = 100.64.0.0

This process repeats again until DC:9F:DB:FF:05:A8 which is somewhere in the 60's I believe.

Curiously, Commotion does this INCORRECTLY because it doesn't use 64 as the first converted number and only goes up to 125 as the last number. We can ignore the way they do this and do it the right way.

"Correction. 100.64.0.0-100.127.255.255 are valid."

Indeed! This outputs the list of the 4,194,304 valid addresses: # nmap -sL -n 100.64.0.0/10

colindean commented 8 years ago

nmap -sL -n 100.64.0.0/10

That’s a neat trick.

THIS is what the ranges should look like: 100.64.0.0 => DC:9F:DB:00:00:00 100.65.0.0 => DC:9F:DB:01:00:00 100.66.0.0 => DC:9F:DB:02:00:00 100.67.0.0 => DC:9F:DB:03:00:00 100.68.0.0 =>

Yeah. The HTML version of the calculator generates IPs for all of those ranges. Sounds like an enhancement to the Perl and Shell versions is in order.
