sub domain?

[RD_Gringa]

I know this is probably a stupid question and I really don't know what section to post it...
What exactly is a sub domain? I can have a few sub domains on my server or I can upgrade and be my own server and run web sites that I want to make later.
Would it be a good idea to start the new site, included in my main site or as a sub domain, then as I get it filled with information to move it to it's own domain?
I don't really know how to expalin it well.
Also, I really need to make some money from my site. I will be leaving USA and need to make at least $600 a month to survive. I have been playing around with different affiliates (travel type stuff) but none are making me much money.
Would it be a good thing, say with the page I have to sell maps, to move it to a sub domain?
With a sub domain I will need to buy new .com names for each?
(also I really have no money to spend to make money. I have to try and use what I already have)

If your domain name is example.com then a subdomain might be subdomain.example.com

The only problem with placing sites on subdomains is that when you try to submit them to directories you will find quite a few will not accept you.

I use subdomains for placing forums separate from the main site e.g. forums.tolranet.com while www.tolranet.com is used for our sales software. In this scenario one advantage a subdomain has over using a folder is it is fairly painless to move it to a second server should the sites out grow a single server.

It's better to build sites on their own domain names rather than growing them on a subdomain then move, if you do move then you have to wait for search engines to update with the new domain.

If you need to make money you should try writing. Lots of webmaster need good writers.

Subdomains and domains are not what you need. You need a service or product that people will buy to click to learn more about.

If you have a host and a domain and your host offers it, you can get another domain name and create a sub domain with your primary site and then point the DNS for the new domain name (the sub domain) to the primary site's servers.

For example, you have a site hosted called MySite.com. You register a new domain name, let's call it numbertwo.com. You create a directory on your primary site named numbertwo. You then go to the registrar for numbertwo.com and point its DNS to MySite.com's servers. You can then visit numbertwo.com as if it is its own site, without usimg the primary domain name. You administer it either through MySite.com or create a password and administer it in a partitioned mode. In other words, the subdomain could be administered by someone else while not accessing your primary domain.

Wrong, that's not a subdomain that is in cPanel terms an addon domain.

RD have you figured out how to create a subdomains yet? Have you asked your host for support?

It is nice to have a goal to make certain amount of money per month? What do you consider your currently skill sets?

I do believe you should know about sub-domain by now. So, if you are thinking of earning money, as mentioned by marcel, try to write good articles as many webmasters are looking for these and you can make some money. Or you can try promoting affiliate products from Clickbank or other Ads revenue sources.

A sub-domain does not need to be registered; as it is a continuation of the registered domain name. The. com itself is a domain and we are part of its sub-domains.
So using the example.com example, you register example.com but you don't need to register one.example.com, two.example.com etc The name server that is responsible for example.com will also be the authority for all of it's sub-domains.
If you are selling space on your web server for others to use you probably are not creating sub-domains, rather you are setting up virtual web sites which is another story altogether.

TOP LEVEL DOMAINS (TLD)

There are two kinds:

The broad categories like com, org, gov, mil, edu, net, etc...
I havn't heard of such TLDs disappearing, but new ones are added, like .eu or .net.
(And .xxx is being suggested again and again - and rejected again and again...)

Then there are all the national domains like fr, de, se, dk, it, tv, hk, tw, etc...
Such domains rarely change, although it sometimes happens that countries disappear (Remember the late sovjet empire, or Jugoslavia..?)

PERSONAL DOMAINS

These are the domains we are usually thinking of.
They can be bought and sold by anyone.

SUB DOMAINS

Another step further down the ladder.
Any domain may (in theory) add subdomains to their own domain.
The question is not whether it's possible, but is it practical..?

In my own case: photo.madsdam.net is equal to madsdam.net/photo
And if I wanted: gallery1.photo.madsdam.net equals madsdam.net/photo/gallery1
But I don't use more than one level of subdomains, in order not to confuse people.

A subdomain would, at least to me, signify 'related' but not 'identical'.
In my opinion: More than one level of subdomains only confuses people (which is probably why spammers love this little trick).

The general advice: Stick to conventions most people already know well!
