It would have been better and still would be better even in
that case to use only one prefix and return the original one
to the RIR.<br>

It's not always so simple.<br>
When we have dns servers hardcoded in thousands machines, or when we
have hosting where clients puts their domains (and we have no
control on client's domains) - return any ip class is not easy.<br>
<br>
On ipv6 - there is problem with renumbering too - but there is no
need to get another class - we have just one class which is big
enough to end of our life ;)<br>
