this request for ipv4 too.

I really don't think making generic named for ipv6 addresses within range 
bigger then e.g. /112 (64Ki addresses) makes any sense.

prehaps it may for small subsets of IP addresses

/64 is 18446744073709551616 addresses, that can't be scanned in meaningful 
time and this number of DNS records would just mess up any DNS servers' 
memory.

making BIND resilient against overflowing memory this way would make more 
sense than creating generic addresses.
