Correct.

<div>A /22 of IPv4 is equal to a /32 IPv6. So you get up to a /32
of v6 for no extra fee.</div>
<div><br>
</div>
<div>BUT... If you are a business, expect only a /48... If you
are a Service Provider, you can probably justify a /32.</div>
<div><br>
</div>
<div>but seriously... a /48 is a TONNE for a business. The only
reason you'd want more is if you have multiple networks in
geographic disparate locations with different upstreams.<br>

<br>
TL;DR version:<br>
<ul>
<li>Businesses: allocate a /48 for every building, no matter how
small.</li>
<li>ISPs: allocate a /48 for every residential customer.<br>
</li>
<li>Consistency is much more important than waste management.</li>
</ul>
