i have some question about the host that provide ns1.yourname.com
1. how can they provide this name server... i mean that what website that provide this name to them
2. is it cost anything? coz if i want it i have to pay set up fee and monthly cost
3. if now i'm reseller and get my own name server ... but later i have my own server ... will i have to buy this name (my name server) from them ?
thank for all

1) They will set it up on their servers and you will register those name serversat your registrars. There will be no cost for registering it.

2) Some charge a monthly fee + setup fee, some monthly fee only, some setup fee only and some no fees at all.

3) When you get your own server, you can change the IP of your name servers and it will works on your server. No cost for changing the IP.

In case it isn't clear, to expand upon #1, when they 'give' you a nameserver (such as ns1.yourdomain.com), what is happening is that they are aliasing *their* nameserver with your name. Somewhat similar if you had two domains pointing to the same web space (and typing in either name would bring you to the same site). If you move, you can set this up again, and 'retain' the name (errrrr... if you want to call it that).

follow up question to #2, and EricDs Reply.

Eric stated they are either Setup Fee, or Monthly Fee, or Both, or FREE.

Where do you Sign up for These?
Where can you get it Free?

Is it lesser 'quality' or something if its Free?

Thanks

Trevor, you get these from the host you resell for.

Some hosts charge for it, some don't. It's up to them, according to their pricing, business plan. Free aliased DNS and paid aliased DNS are not lesser quality or anything, they are actually the same thing :)

Thanks Amigo.


I was told that its better to host your nameservers on a different server.

Any truth to this?

Apparently the reasoning was that, if one of them is down, the entire site doesnt go down.

Does this sound a little bit right?

:D

If you run a single machine for HTTP, email and everything else, you shouldn't have to run DNS on a separate machine. Unfortunately, most DNS cache's will cache a bad entry. This includes web browsers, operating systems, and full DNS cache servers like those found at an ISP.

So yes, for best performance you should have at least two name servers on two separate machines. This will avoid problems if your web server or network connection goes down -- as long as the client doesn't cache a bad DNS entry they'll be able to see your site as soon as the problem is resolved.

For smaller sites this probably isn't much of an issue anyway; especially if you have very little or no downtime, unless your operations are absolutely critical.
