<div><br></div><div>The issue was that if I got a /32, I was not able to break it down for announcement if I want to put part of it in a different (non-connected/aggregated) location. So the policy allows you to get another block to announce in that location.</div>

Quick check:<br>
<br>
inet6num: 2406:C500::/32<br>
netname: TSAGOA<br>
descr: The System Administrators Guild of Australia<br>
country: AU<br>
<br>
That is a single /32, out of the PA block of APNIC. Hence, unless you<br>
convince every single ISP in the world to accept it, the only thing you<br>
can announce is that /32, nothing else.<br>
<br>
More specifics will properly be dropped.<br>
<br>
Please don't spam the BGP tables with more specifics. If you need PI, go<br>
get a distinct PI block for that site from your favourite LIR.<br>

Oh and yes, it will be a lot of fun when some large company is going to<br>
split and then have to split up their IPv6 address space, somebody will<br>
be renumbering a lot of hosts... ;)<br>
