Whops ... so Busybox nslookup does the job of 'getent hosts' (or one of
its alikes) ... and not a separate DNS query as expected.

Hence nslookup shall definitely provide the information required by
Eial and may be a candidate for a '-s' short output format extension
(which may be a useful scripting extension).
