If this machine is your public DNS server (by which I mean the machine which
contains the authoritative zone file for your domain, which will be consulted
when anyone on the Internet looks up the IP address for your website), then
you should look in /etc/bind (and probably named.conf.local there) to find out
the file which contains the appropriate zonefile.
However, the very fact that you ask this question makes me suspect that you
are not running the authoritative public DNS server for the domain on this
machine.
Just to be clear what the instruction is talking about - it means changing the
DNS server/s which *the entire Internet* looks at to find out the IP address of
your web server.
If you really do want to change that information, you will need to find out who
is in charge of that DNS server/s. A good way to start is with:
# whois domain.com <-- substitute the domain we're talking about here
See who the contact details are - it may be a colleague of yours. Make sure
you do the following command from a machine which has an external DNS server
in /etc/resolv.conf (perhaps your ISP's):
# dig ns domain.com <-- substitute the domain again
This will tell you which name server/s the Internet thinks it can get answers
about your domain from. You need to work out or find out who can make changes
to those machines.
