Not true.  Zone *files*, yes.  Because of the wonderfulness that is NAT, my 
LAN's nameserver gives different answers based on whether the query comes 
from the LAN or the Internet.  My named.conf looks similar to:

    view "private" {
        match-clients {
            !127.0.0.1;
            !::1;
            localhost;
            "lan";
        };

        zone "honeypot.net" {
            type master;
            file "internal/db.honeypot.net";
        };
    };

    view "public" {
        match-clients { any };

        zone "honeypot.net" {
            type master;
            file "external/db.honeypot.net";
        };
    };

Then, my zone files looks like:

  internal/db.honeypot.net:

    $INCLUDE ../common-stuff
    www  IN  A  10.5.0.32

  external/db.honeypot.net:

    $INCLUDE ../common-stuff
    www  IN  A  12.34.56.78

  common-stuff:

    @ IN SOA ...
    www  IN  A  2001:470:1f01:224:1::2
    and so on

So, the Internet and my LAN see mostly the same data, except for a few 
records that get answered with different values.
