            Bug ID: 13076
           Summary: IPv6 failure with "nc -v -u
                    [fda0::1f:1c:6405:8075:2b02] 32000"
           Product: Busybox
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Networking
          Assignee: unassigned at busybox.net

  Target Milestone: ---

root:/opt/iprf# nc -v -u [fda0::1f:1c:6405:8075:2b02] 32000
Error: Couldn't resolve host "[fda0::1f:1c:6405:8075:2b02]"
root:/opt/iprf# nc -v -u fda0::1f:1c:6405:8075:2b02 32000
Error: Couldn't resolve host "fda0::1f:1c:6405:8075:2b02"

The expected behavior should be data read from stdin to be forwarded to UDP
traffic on fda0::1f:1c:6405:8075:2b02's port 32000, and responses to come back
to be written to stdout.

bb ping works with the IPv6 address.

even adding fda0::1f:1c:6405:8075:2b02 to the /etc/hosts to allow a named
address did not help.
