Re: [cobalt-users] Re: IP for Raq DNS and hosting

[Emilio <emilio@xxxxxxxxxxxxxxx>]

Usually the secondary DNS should be provided by an external machine since, as Ray points, negates the whole purpose of the redundancy you look fot in a secondary dns.

for example,

adigital.net.mx, which is the main host in my RaQ, has the 204.153.24.234 IP adress (and all my domains in that server are setup using that IP address.
But the secondary DNS is pointed to ns.rtn.net.mx, which is the NOC's main DNS server.

I hope this coments are usefull to you.
