Can you set name server for /48 Ipv6 for RDNS

Hello Everyone

I’ve been trying to find a solution to this for a few hours and still am uncertain if and how this is done.

We have a /32 Ipv6 from Arin. While I can set the RDNS name server for that entire /32 in Arin, I wanted to actually set it for a /48. I did a reassignment as well as reallocation of a /48 from that /32 to our organization but while I can set the name server for the /32, there is no option to set it for the /48.

I could be wrong, but I think this can be done as organizations reassign blocks all the time with RDNS delegations.

So can this be done and if so would someone be able to tell how.
