Now that I have your attention!<br>
<br>
If you're in recent receipt of ipv4 space from the new /8 blocks
then you'll also be feeling my pain.<br>
<br>
If you're a lazy firewall maintainer or a complete idiot in charge
of some important packet routing hardware:<br>
<ol>
<li>you need to stop filtering these new address blocks
immediately, they have (or will have) some busy internet users
on them,</li>
<li>you need to review your firewall or wrapper settings on your
authoritative DNS servers, you need to answer <b><i>non-recursing
</i></b>DNS queries from these new addresses,</li>
<li>you need to read RFC1918, maybe even cover your small cubicle
with its contents, so you know what you should filter.<br>
</li>
</ol>
