# Dumb script to resolve a list of IPs to their reverse DNS and AS details.
#
# This directly calls whois against whois.cymru.com for each line of input
# so if you're going to run it with hundreds of lines of input, maybe don't
# do that and use their DNS zone instead.
#
# Usage
# Pipe a list of counts and IP addresses through me like:

#!/bin/bash

# Started off being just the git/svn stuff from authors below but then got
# hacked on by me to add other silly things.
#
# Needs:
# - A 256-colour terminal
# - A terminal that supports colour emoji (else you'll need to substitute boring monochrome unicode glyphs and maybe colour them with terminal escapes)
# - Powerline font ("fonts-powerline" on Debian/Ubuntu) for the separator chevrons
# - Add this to your ~/.bashrc like:

#!/bin/bash

# bash v4 required because of associative array below.

# networkd-dispatcher hook script that sets every IPv6 address on the system to
# have preferred_lft 0. Put it in for example in
# /etc/networkd-dispatcher/routable.d/50-set-preferred-lft and make sure it's
# executable and owned by root:root.
#
# There's an associative array below where you can list addresses NOT to
