[BusyBox] Problem about the DNS query.

[??]

Hi,
    I find that the busybox send DNS query with content "(none)", 
if I come to busybox send DNS query with "www.busybox.net".
In fact, the DNS query with content "(none)" needn't be sent. 

    I want to resolve it. What should I do? I don't familiar with the
busybox. Need I do something in "libbb/inet_common.c"?

thanks.
