The first thing necessary is a domain, and a
host on which to store the media files for the podcast.
Getting a domain is simple and easy, there are many
domain registrars that can register a domain for
someone for a small fee. Some of these domain
registrars are GoDaddy.com, Dotster, or Network
Solutions are some that provide domains. The domain
registrar will, for a small fee, enter the chosen domain,
provided it is not being used, into the computers that
form the backbone of the internet. These computers will
be told where the domain is located on the internet;
what host it is that holds the domain's information. In
order to give them that information, the name servers
that are held by the host need to be associated with the
domain. Once the domain is in place, a good host
should be found. The host that is chosen should offer a
large amount of both disk space and a much larger
amount bandwidth. Disk space is neccessary because
the site which holds the podcast will be storing large
media files; audio or video files that take up a lot of
space and are difficult to compress. The large
bandwidth is necessary because transferring these large
files many times to many different people will use up
the quota quickly. A good amount of diskspace would
be several GigaBytes, bandwidth should be in the tens
or hundreds of Gigabytes. Once the host is set up, it
should offer you a couple of addresses called
nameservers. Inputting these server addresses into the
site where the domain was registered will complete the
domain setup and allow the site to be found on the
internet.

The next step for people who want to know how to
make a podcast is installing the software necessary to
maintain the podcast. A small piece of coding called
dircaster.php can be used to set up a basic level of
podcast. Dircaster.php can be found easily by searching
for it in any search engine. Once it is located, it should
be edited to reflect the particulars of the domain and
uploaded to the site. Dircaster.php will generate an RSS
file, or feed, that tells the subscriber about the new files
available for downloading. To begin podcasting, create
the audio files that should be podcast, fill in the
information about the file such as date, author, etc, and
upload them to the same directory that contains
dircaster.php. You now have a podcast, and all that is
needed is to publicise the address of the file
dircaster.php. To update the podcast with new
information, just upload the new files. Other things to
make the podcast better might be a site that contains
information about the podcast, but it isn't necessary.

There are many podcast software programs available to
use. Many of them are even free. Because of the
decentralized, geek adopted nature of podcasting, a
wide variety of programs are available, from large
programs with a big footprint that do many different
jobs to tiny little software packages that do the bare
minimum. A package is available for podcast
subscribers of almost any type, and more are being
created everyday.

While some podcast software is designed for home user
computers, much of it is designed to be used online.
There are many packages created so that feed
subscribers can view the podcasts they enjoy from
within a web browser. These software packages contain
both the feed reader like the home user software does,
but usually also incorporate a way to view or listen to
the podcasts online from inside the browser. Much of
this software is used at the podcast directories that
maintain listings of podcast feeds.

Another type of online podcast software is the category
of feed creators. PHP scripting is usually used to create
the RSS file that tells the feed readers where to
download the podcasts from. The scripting can either
create a hard copy of the RSS file and write it to the
server disk when the feed is updated, or it can make it
virtually. When the RSS file is generated virtually, it
doesn't actually exist on the host's server. Instead, the
address of the PHP script is distributed as the address of
the feed. When the script is accessed, it generates the
file by looking at the recent posts at the site and sends
the results to the feed subscriber.
