Superficially cute, but not RFC 2136 et cetera dynamic DNS. Just a
fairly slow method.. (imagine setting the crontab entry to once per hour)
And, people who pipe sed into sed or use constructs like grep|tail|awk
have not Read The Fine Manual enough.
REQ_IP=$(/usr/bin/grep ${PASS} ${LOG} | /usr/bin/tail -1 | /usr/bin/awk '{print
$2}')
...can be done as:
REQ_IP=$(/usr/bin/awk -v pass=${PASS} '$0 ~ pass {ip = $2;}; END {print ip;};'
${LOG})
Finally, to get things back on topic and stop rewriting a "fulhack"[0],
I'm going to go a bit out on a limb and suggest that this perhaps is not
the most appropriate use for nsd. A more feature-complete name server
might be more suited.

Did you move a lot of KOREAN STEAK KNIVES this trip, Dingy?
[0]: A "fulhack" is Swedish for "fast elegant solution to problem", or
"kludge", depending on how one looks at things.
