RIPE

If you didn't already send the change to RIPE, you could use the RFC 2317
technique to redelegate the entire /24 to the customer:

0/24 IN NS ns1.customer.com.
     IN NS ns2.customer.com.

$GENERATE 0-255 $ CNAME $.0/24

Then the customer would make himself authoritative for
0/24.x.96.80.in-addr.arpa.
