Support Round Robin DNS!

[EGS]

Please support round robin DNS!

That means the ability to assign multiple IPs to a single domain! Plesk can do it, why can't DirectAdmin!?

King,

I would like to ask why. Do you want the domain to be piped through two separate networks? That is the only advantage I can see. I have done this myself but I cannot see where a lot of people would need it.

Sometimes people need to know why before they consider it important enough to act on it.

With all respects, really upto the person to decide if they need it or not.

However Round Robin is indeed supported, It is simply multiple A records so just add it again with a different IP and it will work. I use it myself for a clients IRC network.

I never said anything to the contrary. Read my post. I am asking why King needs it so that I can learn. If you want to remain ignorant that is up to you. I want to learn about other possibilities.

I also asked King to post more information about the possibilities so that the DirectAdmin staff might take notice. If DA is thinking like I am currently thinking then its going to be very low of the list because not that many people need it. But if there are other reasons we do not know about then it might go up on the list.

No its not that simple. You cannot add the domain again. You have to add the A records yourself to the current zone file but yes you can do that in DA but again it is not as simple as adding A records.

You must also change the default named.conf file so that the bind will alternate the ip's served.

options {
	rrset-order {
		order cyclic;
	};
};

I would also like to know why you would want to rotate ip's for IRC. What advantage is there?

To spread the irc clients across all the servers evenly.

Fair enough, I misinterpreted the ... lack of correct word .. attitude? intention? I'm sure you understand what I mean anyway. I am use to dealing with people who prefer to shoot someones suggestion down. Glad to know I am wrong .

I know for a fact that it will work in a 'just that simple' method. However it is purely random as clients handle the first response given which can in a sample of say 10, be the same ip 9 times rather than only 5.

options {
	rrset-order {
		order cyclic;
	};
};

See this post.

Awesome, I will have a look at this in more detail, as mentioned above I currently use the quick/nasty method. If there is something with more control It will be of great interest.

As mentioned, it forces clients to different addresses. Most just use this for load balancing and for fault tolerance, However some use some pretty nifty setups with custom scripts to check server loads.

RR DNS does simple load balancing and no fault tolerance. If you are wanting these features get something like LVS.

Which is not Round Robin (at least as I understand it) as King asked for. Therefore my statement "No its not that simple."

.. no fault tolerance.

For IRC, Connect attempt 1 fails, cycle to next server, It doesnt automatically pick it up but it allows for a error to be rectified until picked up by someone who can modify DNS/fix server.

Fair enough, However it is that simple after the slight modification to the named conf, So I personally consider that as being supported. I have put it in place to test and it works quite nicely, I must thank you for the pointer to that thread.

My understanding of round robin I guess was more of a random robin, Whereas this truely cycles the response each time.

Round Robin DNS is supported by Bind not DirectAdmin. I believe King wants to be able to login to DirectAdmin and enable Round Robin DNS from there.
