Re: tlug: Dynamic IP & DNS

["J. David Beutel" <jdb@example.com>]

Regarding IP addresses, in addition to fixed versus dynamic,
you should distinguish private versus public.  Cable and DSL ISPs
often give out private IP addresses (e.g., 192.168.x.x), since they 
need a lot of them, because they're always in use.  

The ISP uses IP masquerading at their gateway to map your private
address to a public one that will work on the Internet.  This limits
the protocols that you can use.  I think it would also prevent anyone
on the Internet from initiating a connection to your machine, even if
you use dynamic DNS.
