You need to get someone to delegate the name to you or no one is going to
know to ask your servers about your domain making it useful on your
internal network only.

The above is overkill if you are just going to have one server on a DSL
or Cable connection. If that is the case that applies to you, having one
DNS server is fine since if your DNS server is down or unreachable so
are your other services.

You might also consider using djbdns instead of bind. It is simpler to
set up and has a much better security track record.

You probably want to wait on doing this until you learn more about how
DNS works. Setting up your own cache to use, instead of using your ISPs
is a good project for doing this.

Which in many cases they do for residential service. Also if you don't
have a static IP address it is going to be problematic to run your DNS
at home.

And any external use involves purchasing a domain name from an appropriate
registrar or reseller. They can be as cheap as only about GBP 6 (USD 10
or so) for a couple of years. At that price one has to wonder why you
don't want to register it. Further, if you fail to register a domain that
you're using internally, and then someone along and registers it, that
external domain will be unreachable by you as your local DNS information
will override it.

Yes, apart from email (MX or A records): if there's no entry in the
DNS at the moment someone sends an email, then their /local/ server is
entitled to bounce it as an unknown domain.

You can either pick a reserved domain name or use some unlikely to be used
top level domain name and have your cache be told to use your DNS servers
to get that information rather than start at the roots (to protect against
the off chance that ICANN decides to sanction the TLD you picked).

If they get back NXDOMAIN they can bounce the message. If they
can't connect to the DNS server to get an answer then the message is
supposed to stay queued for future delivery attempts until a timeout
period (typically several days) is reached. If things didn't work this
way whenever a site lost their connectivity to the the network at
large they would bounce a lot of messages that would have been better
to queue and retry again later.

Absolutely. I used "roaima.lan" for my internal network before I got
round to registering my own domain(s).

So to have a domain name work outside of my lan, I need to register
the domain name with one of the many registerars (pardon my spelling)
on the web and delegate it to my dns server. ...Correct? Is there
anyway I can get my domain registered externally for free (set up any
new servers or purchase any equipment...software etc)?

By the way thanks for all the replies, Im new at this and its been
very helpful.
If you have any good sites or books about this subject I would
appreciate your reccomendations.

I don't think anyone is offering second level domains for free under the
ICANN root. If you are willing to use a third level domain, you could
probably find someone who would be willing to provide one for free.
I think you can get some free domains in some of the alternate roots,
but your domain would only be usable by other people who used the
alternate roots in their caches.

It might be possible to find a subdomain for free (3rd or 4th level
domain), which I did by going up the chain in my country domain. Or for
my dynamic adsl I use subdomains of a dynamic DNS hosting service (do web
search for 'dns hosting').

To do your own forward DNS, you would need at least 1 (usually 2) static
names to dynamic IPs (web search for 'dns hosting'). Otherwise any
3rd party could do forward DNS for any registered name, but public reverse
DNS would require cooperation of your ISP (Turk Telekom).

If you wanted a country domain (.tr) you could start at the link
for registration services on http://www.iana.org/root-whois/tr.htm and see
if they list second level domains that might offer subdomains.
