YouTube script seems to be working very well

General Customizing Pi-hole

Here is an Example for setting up ipv6 for the host file. (I run a dual stack -diverting ads 100% of the time will not work without ipv6 host additions.)

#!/bin/bash

# crappy hack that seems to keep YouTube ads to a minumum.
# over two hours of Peppa Pig and no ads. Taking one for the team...
# grub@grub.net v0.11

# Change forceIP to the real IP from an nslookup of a
# googlevideo hostname so you get something in your
# geographical region. You can find one in your
# Pi-hole's query logs.
# They will look something like this:
#     r6---sn-ni5f-tfbl.googlevideo.com

# as root: run this once then run "pihole restartdns"
# You can cron this for auto-updating of the host file.
# Mine fires every minute:
# * * * * * /home/grub/bin/youtube.update.sh 2>&1

forceIP="24.244.14.177"
#added for ipv6
#forceIP6="2001:4e8:0:b043::11"

# nothing below here should need changing

piLogs="/var/log/pihole.log"
ytHosts="/etc/hosts.youtube"

workFile=$(mktemp)
dnsmasqFile="/etc/dnsmasq.d/99-youtube.grublets.conf"

if [ ! -f $dnsmasqFile ]; then
    echo "addn-hosts=$ytHosts" > $dnsmasqFile
    touch $ytHosts
    piLogs="$piLogs*" # preload with results from all logs
    echo "Setup complete! Execute 'pihole restartdns' as root."
    echo "cron the script to run every minute or so for updates."
fi

cp $ytHosts $workFile
zgrep -e "reply.*-.*\.googlevideo.*\..*\..*\..*" $piLogs \
    | awk -v fIP=$forceIP '{ print fIP, $6 }' >> $workFile
#this section added for ipv6
#zgrep -e "$forceIP" $workFile \
#    | awk -v fIP6=$forceIP6 '{ print fIP6, $2 }' >> $workFile

sort -u $workFile -o $workFile

if ! cmp $workFile $ytHosts; then
    mv $workFile $ytHosts
    chmod 644 $ytHosts
    /usr/local/bin/pihole restartdns reload
else
    rm $workFile
fi


exit

You must uncomment the ipv6 sections and add an appropriate ipv6 address based on the same NSlookup you did for the ipv4 nslookup.

also uncomment the zgrep section for ip6

edit
updated the ipv6 section.
