Dial up and cable modem

[BW Malcolm]

The problem is that both ends of the connection will (probably) have a new 
IP addressed each time he connects to the ISP. My cable modem IP 
changes a couple times a month. A dial up would change every time he 
connects. VNC client needs to know the IP of the VNC server to make a 
connection. 

Two possible solutions: 1) Use a utility to periodically determine the server 
IP and then e-mail it to the client computer if it has changed. 

2) Another is registering a domain name for the server and sign up with one 
of the dynamic IP updating services. (There are a number of dynamic IP 
services, I happen to use www.changeip.com). 

If the IP changes, the dyn IP service sends out an update to the DNS 
servers. It takes twenty minutes to an hour or so to update the DNS host 
lists. Once the DNS list has been updated, one can do a domain name 
resolution to determine the actual IP. 

Not much of an improvement over the e-mail method, but it has the 
advantage of letting him set up web services (FTP, WWW, etc) even 
though he does not have a static IP. 

And perhaps VNC will allow us the option of using of domain names 
someday in the future.
