DNS server

Sat Jun 13, 2009 12:03 am

Hello specialists.

I would like to know if there is any way to implement more than 2 DNS servers in IP->DNS. I mean, I would need to implement a DNS server on RouterOS for all domain names in a company but with more than 2 External (public) DNS. So, computers in the network will have only 1 dns server which is the router itself. Router will redirect dns request depending internet provider.

Supose I have 3 Different Internet providers, each of them provide me with 2 DNS servers so I have 6 DNS servers 2 for each connection. Where I suppose to load such information? because I am able to load only 2.

Is there any DNS packet to do this?

PS: Remember we cannot use provider XX´s DNS services requesting from provider YY public ip.

Thank yOu very much, I hope you understand my question.

i understand your problem and am not sure of a good workaround, but I will say in your case it might be easier to bypass ALL dns servers at your ISPs and just run your own recursive server that hits the root servers directly. It's becoming common to trust your ISPs DNS less and less :)

I'm sorry ChangeIP. I've read your post once and once again, but I am afraid not to understand you very well.
Could you give me an example of you are advicing to me? I would really apreciate it very much. I´ve thought to implement a dedicated DNS server independet from RouterOS, I dont know, may be a Linux over a simple PC. What do you think about?

I would not use Mikrotik's dns servers for more than 5-10 users if I use it at all. I found that it starts to drop requests after a while. Clear the cache, problem is gone for a while. Rather get yourself a linux box and load bind9 on it, installation is pretty easy.

Heres my "site" (if you could call it that) http://randomnetworking.site90.net . The first link is a caching DNS server guide I made.
