For those people without permanent connections to the net it's
difficult to have a static domain name. Dynamic DNS servers allow you
to obtain a domain name even if you only use a dial-up IP address.

Well, just as an exercise, I applied for the domain name
jpssolutions.nws.net. Then I wrote a short shell script that fires up
Apache and registers my current dial-up IP address with nws.net. As
long as I'm on-line (pretty short since I don't feel like giving NTT
more of my money ;-) you can reach my web server at
http://jpssolutions.nws.net Once I drop the connection the server is
gone only to return at a new IP (with the same domain name) the next
time I run the script. Pretty nifty :)

What use this has, I leave up to you....

All you have to do is run the C program that updates nws.net's routing
table.

Nope, this appears to be a 0 cost way to get a static domain name with
a dynamic dial-up IP address....

How long it lasts is another question.
