Assign the entire ipv6 block [closed]

I want to be able to use any subnet in a nodejs (with localAddress with the got module for example) program on ubuntu 22.04

The only way I found is to add each IP manually in netplan (xxxx:xxxx:xxxx:xxxx:1/64, ::2/64, and so on), but adding all the IPs like this would be impossible, is there a way to assign the whole block?
