DNS noob! Please Help.

[Haliway]

Well I am getting my hands dirty with DNS for the first time and need some guidance. I have a server on my LAN that has a Public IP address Nated to it. I can access this machine from the out side world using the IP but would like to assign a name associated to it. I tried creating a forward lookup zone but still no luck. Any help is greatly appreciated.

Thank you.

You'd want to register alias/cname with your ISP to see it from the outside.

Do I need to registar everything I creat in DNS even after my FQDN is registered?

Assuming you don't have your own DNS in a DMZ that your ISP is forwarding to: anything you want resolved from the Internet needs to be registered publicly through your ISP or anther public DNS provider (register.com, for instance).

I should have been more descriptive. This is a cooperate network with it's own DNS on the DMZ.

Ok. do you have a domain registered already? This is basically something you would just do through your registrar.

Yes

You need to contact your registrar and register your nameserver with them. This will make your DNS server authoritative for "yourdomain.com".

The simple answer is, contact your provider, tell them what you want to do, and they'll get it set up for you.

OK, I thought once I was registered with the domain name i.e (abc.org) I could create i.e (123.abc.org) (456.abc.org) on my DNS box without haveing register anything else. I guess thats not the case.

Thanks for clearing that up!

When you say "123.abc.org" or "456.abc.org" you are talking about sub-domains, and if you've registered your DNS box as the authoratative DNS server that responds to requests for "abc.org", that SHOULD include any sub-domains.

What exactly is the problem you're having?

 

[Haliway]

It's more of a convenience thing then anything else but I have a server on the network that I access remotely thru Terminal Services using the Public IP address. I'd like to create a sub-domain name (***.abc.org) that will direct me to the Public IP I have Nated to the server. This is a corporate environment with a registered DNS server.

HELP PLEASE!

Yes, then lhuegele is right. If you've already got the top level domain registered as authoritative, then you should be able to create hosts and subdomains.

 

[Haliway]

OK, thats great news now I just need instructions on how to do this. can you explain or do you have a link I can follow. Again thank you for the clairifcation!

Are you using Microsoft or BIND?

 

[lhuegele]

Using Microsoft, it's very simple actually, but you have to remember that the server you want to put in a subdomain would actually be "server.123.abc.org" and not "123.abc.org". If you want this server to be "123.abc.org" you'll just add a new HOST record (A record) to "abc.org".

To create a sub-domain, right-click on the forward lookup zone "abc.org" and select "new domain". This will create a new sub-domain inside "abc.org". Then you have to add the server (host record) to this sub-domain, giving it the external IP address of your server in question.

Personally, if this were me, I would just create a new host record on the main "abc.org" domain, give it a different name than what the server is called, and assign the external IP address to this new record.

Hope this helps.
