DNS configuration question

[MindServer]

Hi,

I'm configurating the DNS, and i have a question:

In OVH you can buy "IP Failover"

You recommend me use the defaults server's IP for create DNS?, or you recommend me only use "IP Failover" for all DNS?:

-For example with defaults server's IP:

ns4.mydomain.com -> 0.0.0.0 (defaults server's IP)
ns5.mydomain.com -> 0.0.0.0 (IP Failover)

-For example with only IP Failover:

ns4.mydomain.com -> 0.0.0.0 (IP Failover)
ns5.mydomain.com -> 0.0.0.0 (IP Failover)

Which method is preferable for hosting provider?.

Thank you very much. Have nice day!

For failover DNS it's really about preference but redundancy is always better - if something happened with your nameservers - correctly configured failover DNS could allow your sites to continue to resolve, pending your server wasn't down. It's definitely worth looking into if you're going to be acting as a provider for people's sites.
