DNS Question
Okay so I've dealt a lot with simply putting entries into DNS for internal usage. For example we have IP cameras that I added DNS entries for and gave them names instead of using IP addresses. However we are doing something a little more advanced now.
Our Internal DNS server sits on a SBS 2010
We installing a new server that host a certain application that will run on our network. It will be used internally, but also it will be used externally. Apparently it will be a website the users will be able to log into.
On my part I was asked to do the following:
Okay I can easily do the linking of the IP address to the internal name, but what is a external DNS? And how do I go about that making it reachable with our public IP? I know my public IP if that helps.

The server name will be test.example.org Can you add that name to your external DNS server and internal DNS server? The external should be pointed to a reachable public IP address and the internal would point to the local IP subnet.

How do I view to see if I even have a external domain setup? I'm just not familiar with the terminology or concept of external domains. I just personally deal with our business internal dns for example site. Local
OK, if you run a 'whois' against the external DNS name, that should tell you the provider it is with. Usually its with an ISP such as demon or BT?

Oh are you saying that a external DNS is just another term for a service such as www.godaddy.com?
No external DNS is the same as internal DNS. Its the method you resolve domain names to ip addresses. Only it works on the public networks.
If you ping www.google.co.uk, you will obviously return back an IP address. So for your domain, you need to find who owns the domain, and ask them to create an A record for the record you require

We don't even have a website, so how do we even know anyone is hosting anything to begin with?
Do you have an domain then? If you havent got an external domain name then you either need to purchase one or dont use an external dns name. Just access the resource direct to IP address

We have a local domain for active directory and group policy purposes.
This application will be used internally AND externally.
I guess that was kind of my main question, what is a external DNS? I'm not well versed in DNS terminology, but I've figured it out how to work on them usually trial by fire.
But you stated purchase, so it sounds like again a external DNS is just another word for a DNS hosting site like godaddy.com? Because I've set up one of those before for a personally web server of mine at home if that's the case.

Hi,
If someone sends an email to a person in your business, look at the email address they use - the part after the @ is your domain.
It is also possible that you don't have your own domain, and you use someone else's (like gmail) in which case your email address(es) will be something like:
mybusinessname@gmail.com
In your first post, you said:
Accepting that you changed the domain to example.org for the purposes of posting here, whatever it really is, that is your (external) domain name.
If you do already have a public domain, somebody (and ISP usually) is hosting your domain name, and they are likely also providing your public DNS service on their own DNS servers. It is them you need to contact and ask them to add an 'A' record for test.example.org (changing example.org back to whatever it really is), and point it to whatever publically routable IP you are wanting to use.
HTH,
Alan.

Our e-mail system is hosted externally.
If I host a external domain name, example.org at Godaddy.com for example, do I have to involve the ISP at all?
Our computers (around 50) point to our gatewat, a Cisco 5510, which uses Google's DNS servers. When we set them up, we didn't use our ISP's because they're always seems to go down.
I remember way back in the day we had to call the ISP about changing a DNS entry for our mail server (This was before we outsourced the mail servers to headquarters) because we changed the domain name. So we changed the MX record here locally on our DNS server that's hosted on the SBS 2010, but it wasn't working, so again as mentioned earlier we had to call the ISP to update their record..Not sure if that had to do anything with this situation.
Can I simply just host the new domain on godaddy, then port forward it to the server located on our site?

Thank you very much, that was very clear. I ended up having to start a new domain on GoDaddy for it to work, but now I understand how the process works. Thanks!
Glad it worked out for you :-)
If you send them a request to setup an A record, and point to whichever external IP address they should be able to set that up for you
Cheers
