[Unbound-users] DNS multiplexer?

[Jaap Akkerhuis]

    > Does anyone know of any code that will let one to run Unbound and NSD on 
   the same IP address and still use port 53 for listening on both?

    Can you not run NSD on the same IP address but different port,
    and then set unbound to forward queries for the zones NSD is
    authoritative for to localhost:<port>? I.e. unbound listen on 53.
    
As far as I know, one can. See "Forward Zone Options" in man (5)
unbound.conf
