you for the duration of the connection, although your ISP may also change your IP address
during the connection. Each time you connect, you are assigned a new IP address.

you registered "happy.dynamip.com". You dial into your ISP. The DynamIP
application recognizes your newly assigned IP address and contacts the DynamIP server. The

This way, anybody who types "happy.dynamip.com" in their web browser is

What if I don't want to use the
"dynamip.com" domain in my address?
By default, your
address will be "something.dynamip.com". You may want to use the free
redirection service at http://come.to to redirect people to your DynamIP address, without letting them know you
are running DynamIP. Or, if you have your own domain, you can set up a
CNAME record in your DNS server to point to your DynamIP address. Or, you could set up your web server to
redirect people to your DynamIP address for certain pages or files.
Lastly, you could set up frames on your main web site that load
certain pages from your DynamIP site.
You must have Internet Explorer 3.01 or later installed in order for the DynamIP
application to function!
