Setup Public DNS 1

[Caustic]

I've used MS DNS internally for years both AD integrated and standard DNS. But I have a question about external DNS servers. It's more of a "what do I do" question instead of a "how do I do it" question.

I'm discontinuing a contract with my ISP that previously handled the DNS for a namespace my company owns. I've never set up a public DNS server before and after reading a lot of the articles available on various sites I'm a little confused as to how to proceed.

Is it as simple as putting a server on a public IP address and then going to whatever website the domain was purchased from and giving them the IP of that new server?

Thanks for any info.

basically, if ur enterprise is S&M, i will recommend let your ISP to host your DNS server, just forward query to ISP DNS on your AD DNS. and all servers/workstions are pointing to AD DNS for name resolutin.

if you are charging a big enterpise DNS, you will pronbably mainatain your own DNS(or piblic DNS), but be aware of puting DNS in DMZ. I guess in this case, most likely, your company will hire consultant to set it up. there are lots of best practice to follow.

Goodluck

Thanks for the response.

I guess my situation is the second one. I want to move from the ISP handling the DNS to hosting my own public DNS. But I'm not sure how to go about it. Do you have any suggestions for online resources or reading material?

You will need to speak to the registrar that your name is registered with to get your DNS servers registed with the top level domain so that the glue records are in place. They may insist that you have a minumum of two DNS servers to host your own. Any less would be unwise.

You will also need to allow both UDP and TCP ports 53 through to your server although UDP will be used the most for queries.

If you only have one server then you could host the primary on your own site and then have your ISP or another DNS provider slave off your server as a secondary which would give you a little bit of redundancy. Both would have to be registered with the registrar.

I find this interesting.
Because I am having DNS issues. So infact what you are saying is that DNS should be registered. You see we are using Internal DNS's but they are not working as expected.

We do have two external DNS's that were giving by our ISP.
So it would be smart to use both of them as DNS or just use one and have the second DNS be one of our Internal servers?

ChrisAC,

Thanks for the information. That's exactly what I was looking for. I used a whois to track down the place where it was originally registered and contacted them to get our username information so we can manage the account again.

Carlo,

This all depends on if you are hosting your own servers for your own domain or not.

Start another thread and we'll have a look at your problem.

Chris.
