There are only two places to specify nslookup options:
as command options, or from the resolver configuration data set.
Only a few of the options may be set in the resolver configuration
data set. The command options always have precedence over any option
configured in the resolver configuration data set.
Only the following options can be specified in the resolver configuration
data set for v9
nslookup:
- nameserver/nsinteraddr
- options ndots: n
- search
- domain/domainorigin
The z/OS® UNIX
nslookup command
uses a private resolver that is different from the resolver used by
other z/OS UNIX socket programs. The z/OS UNIX
nslookup command
has the following functional differences:
- z/OS UNIX nslookup does not use
SiteTables (for example, /etc/hosts) for host name resolution.
- Only the built-in translation table is used for nslookup.
