The $GENERATE directive of bind9 makes it possible to autogenerate the reverse mapping for a range of IPs what is really helpfull for reverse dns of a dhcp range. But it seems that the $GENERATE directive can only generate the reverse dns for a /24 subnet. So is there an easy way to autogenerate the reverse mapping for example the range of a /18 subnet whitout a zone file with more than 16k lines?
A solution with another DNS server or a way without $GENERATE is also welcome.
Hint: The whole reverse zone is a /16 not a /18 but I only need to generate the rDNS PTR RR for the range of a /18.
