View Full Version : Remote DNS, round robin and such...

I saw webhostingtalk is using easydns for hosting their dns info.
I checked their site and it looks like I couldn't afford that (24.95/month) with my many domains.

My registrar bulkregister offers hosting for dns with round robin and unlimited subdomains and up to 200 MB of dns traffic per year for $5 per domain/year in the basic version without email forwarding.

Is there already a script or something available to make round robin exclude servers, something which would check all the servers and if necessary log into the bulkregister dns account and remove the IP of that server.

Did anybody already use bulkregister for dns? Is their dns tool reliable? I think they could be reliable because they need to be that for their domain registry biz?

I don't know the DNS system of BulkRegister -- but if you really have many domains - why not do DNS yourself?!?

Then you would not need to pay a fee per month for each domain, and you would have more control.

Regarding round robin: I don't know any scripts for bulkregister, but I have set up my own dns system to simply ping a list of servers every minute, and if one of them fails, it will be removed from the round robin list in the database.

I could of course make it more advanced (like checking for if Apache or Qmail went down -- sometimes that happens when you can still ping the server). But it works for me... and I receive a BigBrother warning by pager anyways if something should fail.

The idea with bulkregister is that it would be extra reliability, they say something like hosted on several servers on 4 different networks etc...


Not sure though if it is a good idea.

Well, how much reliability do you need?

For example: Are all your servers on the same network?

If yes, would it matter to you if the nameservers kept working even though all access to your network (and all your servers) was cut off?

Normally most use two servers to do DNS. It is quite unlikely that both servers should crash at the same time.

(Personally I use 3 DNS servers.. but that's just me being paranoid)

DNS isn't really the premier protocol to perform redundancy with. If you are serious about redundancy, buy a product from F5 or Netscaler. They work best.
