BIND Round Robin

[Tony Teo]

Hi,

I need some tips to clarify some DNS issue I got.

A primary and a secondary name server's ip address will be required to
register in the internet root servers for a certain domain.

Qns 1 : So when a query is send from a LDNS to the root servers, are
both the name servers being return back to the LDNS for subsequent query

?

Assuming that both address are returned to the LDNS.

Qns 2 : Does the LDNS always query the primary name server ? When will
the secondary name server be query ? Is it under the event when the
primary become unavailable or unreachable ?

Qns 3 : Does the LDNS uses round robin algorithm  between the primary
and secondary name servers ?


Thanks
