Description holgerk 2016-03-08 18:08:04 UTC 
When looking up an integer number with busybox nslooup it always resolves it successful to an IP address: e.g:

nslookup 1
Server:    192.168.80.13
Address 1: 192.169.80.13 myserver.local

Name:      1
Address 1: 0.0.0.1

The nslookup version coming with the bind package would return an error.

I believe this is fixed with FEATURE_NSLOOKUP_BIG:

$ busybox nslookup 1
Server:         172.16.4.1
Address:        172.16.4.1:53

** server can't find 1: NXDOMAIN
