You can set another peer nameserver to be a public, private,
commercial, or other name server as follows:
; Zone file for abc.com.
$TTL xxx
@ IN SOA ...
IN NS ns1.abc.com.
IN NS google-public-dns-a.google.com.
IN NS res060.ns.uu.net.
[Note the blank space in front of the [unneeded] "IN" in each "NS"
above: they each inherit the LHS from the record above.]
Assuming that an IP address that is not yours will "never" change is a
frightening assumption, especially when proved untrue. Don't plant
someon else's IP address in your name space, unless there is a firm
agreement between yourself and them about why it's there and how changes
will be communicated.
