busybox-1.23.1-r1 appears to not perform any DNS resolution, for its functions that would normally do so (ping, wget, ntpd, etc).

Example of issue:

$ busybox ping google.com
ping: bad address 'google.com'
$ /bin/ping google.com
PING google.com (216.58.216.206) 56(84) bytes of data.
64 bytes from ord31s21-in-f206.1e100.net (216.58.216.206): icmp_seq=1 ttl=53 time=37.4 ms
64 bytes from ord31s21-in-f14.1e100.net (216.58.216.206): icmp_seq=2 ttl=53 time=38.3 ms
64 bytes from ord31s21-in-f206.1e100.net (216.58.216.206): icmp_seq=3 ttl=53 time=45.3 ms

tcpdump confirmed no DNS resolution performed.  nsswitch.conf is at its defaults, resolv.conf contains only google's DNS servers, resolution works fine except with busybox.

Appears to affect at least x86_64 and arm.

Uncertain how long this has been an issue as I have not used these utilities before.  Found a bug filed against Raspbian for busybox 1.22 with the same apparent symptoms:
