If you load the following on your system you will get the NSLOOKUP

Resource
ID Option Feature Description
5770SS1 31 5050 Domain Name System

I've removed that option from many lpars because IBM uses such an old
version of bind that one fails audits. I wanted to ensure that it just
could not be started, accidentally or otherwise.
I really feel that the nslookup command is a 'client' command and not a
server command and should exist independently of that option. However I'm
trying to get work done so instead of submitting another RFE I'd like to
find an IBM i based alternative. (Noticed I dropped off the word
"native"?) QP2TERM and QSH both lack the 'ix commands HOST and DIG
(unless you load option 31). Are they there but just not in the default
path?

nslookup is part of the BIND distribution.

I can tell you that in FreeBSD nslookup is no longer available
once BIND was replaced by "unbound". "dig/nslookup" is now "drill".

You still can install BIND from the "ports tree" in FreeBSD if needed.
Here is a snippet from the file HISTORY included with the port describing
what you are looking for taken from the file fetched during the port install
http://ftp.isc.org/isc/bind9/9.9.9-P4/bind-9.9.9-P4.tar.gz

snip..
BIND 9.7.0

BIND 9.7.0 includes a number of changes from BIND 9.6 and earlier
releases. Most are intended to simplify DNSSEC configuration.
snip...
- A "tools only" installation mode on Windows, which only installs <--
dig, host, nslookup and nsupdate.
- Improved PKCS#11 support, including Keyper support and explicit
OpenSSL engine selection.
