Making DNS public

[nagetech]

As you might remember, I made a previous post regarding setting up a 2k Domain @ home...and i have scccessfully done that, and its getting better...

I had a new idea....since i have DNS, and i know everyone needs DNS to be online, i figured, why dont i make my DNS public just for the sheer hell of it?

It's a new project of mines..and i hope it's doable......

when i say public, i mean how would people be able to reach it through my router?

i have a t1 connection hooked up to a netgear rt311 router..and my DNS Server Ip addy is 192.168.0.20....what port would i have to forward in the router so when people point to 24.188.196.21, it would forward itself to the DNS server?

i was thinkin bout putting the DNS server's IP in the "default" slot, which totally UNBLOCKS that one ip...but id rather just play it safe and forward only waht i have too...thanks :)

UDP and TCP port 53.


For me answering this question, do I get anything :D . j/k good luck with your sweet T1.

Make it a SpeedGuide Counter-Strike server :)

cool man , i thought the netgear rt311 was a cable/dsl router?

In theory, cable and t 1 are almost the same thing....but cable isnt locked @ 1.5mb....and t1 is 1.5mb up and down....

Did my answer work?

[nagetech]

Let's find out...it works for me..but then again..im on the inside..

throw in 24.188.196.21 as ur primary DNS ..nothing for secondary...and tell me if you get a reslove

by the way..what kind of connection you on

[nagetech]

i HAVE s small question...with DNS....is there anyway i could review on my server...like what requests were made?

does the DNS keep a log of what ip's made what requests..and waht the request was resolved too?

thanks for all ur hlep

[master7]

It works for me! I'm on ADSL

[newbie1]

hey nagetech you have a pm

[nagetech]

Hum..nice to hear it worked...anyone else wanna try it out just to help me out?

by the way..when you typed it in...did you reboot first to amke sure the settings were used?

cause on DSL..you have PPPoE...and sometimes the software used to sign in over writes everytghing else...unless you're behind a router

[newbie1]

it works

[nagetech]

Man..this is very good to hear...

If you are using Win2K Server all you have to do is open up DNS through the Administrative tools to see which IP's have been resolved to a name. As far as who made the request for the IP, I don't think there is any way to tell.

Just out of curiosity, what IP's do you have your forwarders pointed too?

CHECK UR PM

Here's what my DNS looks like on my server at home. I don't make my DNS server public, it's only to serve my client machines. If you start opening those folders on the left, you will see the names of every web page opened, then eventually the IP of that site.

When I asked what IP you had it forwarded to, is this. I have mine forwarded to the DNS servers of my ISP. If you don't have the web page cached on you local server, that your client is looking for, then your server needs to know were to look (or forward) that request to.

But, I'm in the process of pinging all of the root DNS servers listed on the root servers tab. These servers are the ones (I believe) that are aurthorized to be DNS servers by Internic (http://www.internic.net/index.html). I want to use the one with the lowest ping, so that I have the fastest resolve of any IP's not cached on my local DNS server.

I think you really need to check into this more before you set up a public DNS server. You may wind up getting into deep ***** with your ISP.

You have a business class connection - get yourself a proper router. It may end up being your bottle neck. Look at netopia, cisco, or nexland if on a budget - just friendly advice.

there is more to a connection than simple bandwidth. T1's are great for multiple users as it balances a little better. Its all about the number of channels...
