One Domain, two DNS Servers on Seperate ISP's for Failover.

We have two ISP's example: 8.3.56.xxx and 102.36.100.xxx. Lets say 102.36.100.xxx is the primary IP address for our domain and it works fine. We have two DNS servers, one primary and one secondary, on this ISP connection. Can we move our seconded DNS server (NS2) to the other ISP for a fail over if our connection to the primary fails. We have added the second ISP address in the reverse lookup zones, and the A recorded in the Forward Lookup zones for the secondary IP. We have also added a second MX record along with a matching A record for our email on both DNS Servers. Am I going in the right direction? Or is this even possible?

We need to have availability for email and access to our website if the connection to our primary ISP fails (it has done so).

Thanks in advance

There are companies that offer dynamic DNS services, such as Dyn (http://dyn.com/). They monitor your servers/services on your primary ISP and automatically change DNS to your secondary when needed. Automatic failback is also an option.

Thank you for your suggestions. Not sure that management wants to have the cost of a hosted solution but if I cant get this to work then that may be the way we need to go.

Asavener; I do have the records in sync on both servers and both servers are primary and both servers are listed with our registrar. I'll double check all the configurations and contact our registrar to be sure.
