What is 'DNS'?
DNS stands for 'Domain Name System' and is the master naming scheme for
the Internet. DNS allows a web surfer to type in an address like
http://www.badblue.com and have it automatically resolved to the
correct IP address so that its content can be delivered to the user.
What is 'Dynamic DNS'?
When a typical PC connects to the Internet through a dialup, broadband
or other connection it is often assigned a random IP address (usually
through a process called DHCP).
The problem with a random IP address (if you're trying to run a server
on your own PC) is that other Internet users don't know your new
address each time you connect. Thus, users can't easily locate your
PC when you run BadBlue or any other type of server.
Dynamic DNS helps solve the problem. BadBlue includes DNS software that
determines when the PC's address has changed and sends the change to a
master DNS server. For example, BadBlue supports a naming service
called DynDNS.org. At DynDNS, you can sign up for a free dynamic DNS
account such as jsmith.dyndns.org.
This will allow you to distribute a DNS name that your users can type
in to their browsers' address bar (http://jsmith.dyndns.org) rather
than an IP address which often changes frequently.
Starting with version 2.1, BadBlue includes Dynamic DNS software that
allows you to easily set up your own DNS name through DynDNS.org.
Whenever you're online and running BadBlue, friends or colleagues will
be able to 'surf' to your PC using their browsers.
This makes it easy for web surfers to explore your PC and download the
photos, music, videos or business files you've designated as shared.
