Hi,
I get the same with the latest git source, on x86-64 - but only when
not using glibc.
It's definitely a bug. I disabled nscd, changed DNS to just 8.8.8.8,
and tested musl libc, glibc, the "real" nslookup.
Here's the output:
$ /usr/local/bin/busybox nslookup example.com
Server: (null)
Address 1: (null)
Address 2: 127.0.0.1 localhost.localdomain
Name: example.com
Address 1: (null)
Address 2: 93.184.216.119
$ /usr/bin/busybox nslookup example.com
Server: 8.8.8.8
Address 1: 8.8.8.8 google-public-dns-a.google.com
Name: example.com
Address 1: 93.184.216.119
Address 2: 2606:2800:220:6d:26bf:1447:1097:aa7
$ /bin/nslookup example.com
Server: 8.8.8.8
Address: 8.8.8.8#53
Non-authoritative answer:
Name: example.com
Address: 93.184.216.119
Thanks,
Steven
