Description

We want to write a script that calculates:

  • the number of relays, and
  • the consensus weight fraction of relays,

in the consensus that:

  • have an IPv6 ORPort,
  • support IPv6 reachability checks,
  • support IPv6 clients, and
  • support IPv6 reachability checks, and IPv6 clients.

In order to provide easy access to these statistics, we propose
that the script should:

  • download a consensus (or read an existing consensus), and
  • calculate and report these statistics.

We could write this script using Python 3 and Stem:
https://stem.torproject.org

The following consensus weight fractions should divide by the total
consensus weight:

  • have an IPv6 ORPort (all relays have an IPv4 ORPort), and
  • support IPv6 reachability checks (all relays support IPv4 reachability).

The following consensus weight fractions should divide by the
"usable Guard" consensus weight:

  • support IPv6 clients, and
  • support IPv6 reachability checks and IPv6 clients.

"Usable Guards" have the Guard flag, but do not have the Exit flag. If the
Guard also has the BadExit flag, the Exit flag should be ignored.

The script should check that Wgd is 0. If it is not, the script
should log a warning about the accuracy of the "Usable Guard" statistics.
