Dynamic hosting works by having a client (your server) notify the DNS server
of it's ip address so that the records can be updated dynamically.  This
usually means that one must become a host name on someone else's domain
name.  Check out hn.org for more information and possibilities.

One of the command line parameters of dhcpcd is that you can request an ip
address using the '-s 1.2.3.4' option.

I have since created a new script to maintain my connection.  Usually the
script will just idle...but lately things in the land of AT&T(now
AT&T/Comcast) have been rocky.

(I'm going to attach the script so that it preserves long lines.)
