On Linux, neither Chrome nor Firefox are working for me, yet:<p><pre><code>    $ host _why.usesthis.com                                                       
    _why.usesthis.com has address 74.207.245.100
</code></pre>
odd.<p>[Edit: Looking at darshan's post below, I understand why:  host (part of the BIND distribution) uses its own resolver; everything else goes through the system facility (i.e. glibc). I still don't know how to fix it, though.]
