I use the attached (hope it comes through) script in
combination with some tools (yups I can't avoid awk ;)
as described in the beginning of the script to register
the primary (LAN) interface of my laptop whereever I

For the rest just follow the documentation on:
http://ops.ietf.org/dns/dynupd/secure-ddns-howto.html

Greets,
 Jeroen
