    Default Bind View options and some other queries ...

    Hi ... linux newbie here ... got a few queries regarding BIND

    System--- x86-rhel-52-01 virtual guest ||| Bind 9.3.4

    1) I wanna differentiate b/w 'match-clients' and 'match-destinations' options defined a VIEW clause to see them working in test setup ! how can i achieve so ?
    EXCERPT from a bind doc
    "The match-clients statement defines the address_match_list for the source IP address(es) of the incoming messages. The match-destination statement defines the address_match_list for the destination IP address of the incoming messages and may be used with multihomed servers or to differentiate, for example, localhost behavior from all other IP address sources."

    But how do i setup the above scenario ...

    2) why don't we receive an answer for a SOA query of rs.internic.net ||| although NS and A queries are do ANSWERED positively.
    using these public dns server for querying SOA
    a) 208.67.222.222 | 4.2.2.1 | 8.8.8.8
    b) Recursive resolution done by rhel guest by itself using named.root ROOT
    hints.
    Is that possible, we have a public dns domain of which we can't query SOA... despite the reason that this info should be mandatory PUBLIC for a PUBLIC domain ! (correct me here)

    3) Query regarding STUB zones when they are created for public domains
    on our test System ... |||
    Public domains causing Confusion --- apple.com | nokia.com
    Public domains obeying ---- yahoo.com

    why doesn't our BIND server received HOST A RR for the NS servers ( mentioned in NS RR ) for the apple.com and nokia.com domain whereas it does received HOST A RR for NS Servers ( mentioned in NS RR ) associated with yahoo.com domain ... why is that difference arising when we try to create STUB zones of these above mentioned PUBLIC domains ?

    See the detailed conf. and output difference here

    Default Update

    3) solved using minimal-responses yes; option which defaults to no
    Tested in private namespace and results speaks that its [-o< done.

    Below is Pro DNS and BIND excerpt
    minimal-responses
    minimal-responses ( yes | no ) ;
    minimal-responses yes ;
    If minimal-responses is set to yes, the server will only add records to the authority and additional data sections (see Chapter 15) when they are required by the protocol, specifically delegations and negative responses. Since the effect of this is to reduce the data volumes sent, it may improve the performance of the server. The BIND default is no. This statement may be used in a view or global zone clause.
