Urgent: DNS and IP Addressing
Ok..i'm not sure if you can do this but..
We have a server at my company that is running a lot of services like mail, web, etc. We're trying to make a disaster recovery plan where we have 2 ISPs in case of an emergency.
Would it be possible to have a website like www.google.com resolve one public IP address and if that fails resolve another IP address? It's like linking 2 IP's to one DNS name. I understand that round robin dns does something like this but is only used for load balancing and not disaster recovery where if one IP goes down, the other IP will take over, but both will be listed for one DNS name. Anyone know how we can do this?
Re: Urgent: DNS and IP Addressing
this should have been put in the "General PC" section...
anyway, isnt that what the alternat dns is when you register/edit a domin?
Re: Urgent: DNS and IP Addressing
I wasnt sure...
Is the alternate DNS name the redirect site for the primary DNS name and will allow me to go to the second IP address if the first IP address fails?
Re: Urgent: DNS and IP Addressing
That is what i always thought, but maybe somone that knows more about it should either back me up, or tell me i am wrong!
Re: Urgent: DNS and IP Addressing
What you want is a backup name server. All you need to do is add a second name server to your zone file.
