Question about the content of the /etc/resolv.conf

[John]

Hi all,

Question about the content of the /etc/resolv.conf

Our /etc/resolv.conf looks like that:

# more /etc/resolv.conf
domain amsterdam.nl berlin.de brussel.be vienna.at madrid.es helsinki.fi

nameserver 194.229.188.24
nameserver 194.229.188.25

!!Note:
The domain amsterdam.nl will be resolved by the local DNS's, but all the
rest (berlin.de brussel.be vienna.at madrid.es helsinki.fi) are resolved
by foreign DNS's. Because in the /etc/named.conf all the foreign domains
use type forward.

zone "berlin.de" {
        type forward;
        forwarders {
              213.162.88.3;
              213.162.88.4;
              };
        forward only;
};

I have ever followed the HP DNS course and they mention to put all the
domains in the /etc/resolv.conf
Is it necessary to put all the domains (berlin.de brussel.be vienna.at
madrid.es helsinki.fi) behind the keyword domain?? If yes WHY?? If not
can I remove them??

Please let me know.

Thanks advance,

John
