Can't remember exactly, but this is what I used in past to generate the list of things to block on the Kindle itself.

# Block unwanted domains with the /etc/hosts file
echo ".d" | sqlite3 /opt/var/local/reg/ServerConfig.db \
    | awk -F, '/VALUES/ {gsub(/\047/,""); gsub(/\;\)/,""); print $3}' \
    | grep -o '.*\..*\..*' \
    | grep -Ev 'com.lab126|DOMAIN|WEBSITE|THUMB|openid.assoc_handle' \
    | sed 's/);//;
            s/^http:\/\///;
            s/^https:\/\///;
            s/\/.*//;s/:.*//;
            s/|/\n/g;
            /^\./d;
            /^\[/d;
            /^$/d' \
    | sort -u \
    | while read -r; do
         echo "Blocking host : $REPLY"
         grep -q "$REPLY" /etc/hosts || echo "127.0.0.1 $REPLY" >> /etc/hosts
     done

From an old backup, I think it's this one in particular to block updates, but it was a long time ago....

127.0.0.1 firs-ta-g7g.amazon.com
