These rules do not exist for fun.

If you pretend, that you have two nameservers, but have only one, that's worse than having only one. If you believe it or not, most hosting companies have two or more nameservers. There are even free secondary providers, so where's the problem?

fast question:

SECONDARY_DNS = if for some ip or for some ns.foo.net
is for IP correct?

thaks

UPDATE--
okay i know now is for IP
