Answer for a specific host, but recurse for all others within a zone

On your resolver, create a zone called
and only have one entry, an A record for the zone itself. something like this:
---begin something.xyz.com zonefile---
something.xyz.com. in soa ns1.abc.com. hostmaster.abc.com. (
something.xyz.com. in ns ns1.abc.com.
something.xyz.com. in ns ns2.abc.com.
something.xyz.com. in a 192.168.100.15
---end something.xyz.com zonefile---
This will still allow www.xyz.com and mail.xyz.com to resolve, but will NOT recurse for www.something.xyz.com. If you want that to resolve, you'll have to add that to the zone as well, as you're claiming authority for something.xyz.com and everything "to the left" of that as well.
It just occurred to me that you could also provide a local answer for a single name with RPZ, which would give the benefit of continuing to recurse for www.something.xyz.com.
