    dnsmasq: dnsmasq --rev-server support
    
    This is functionally the same as --server, but provides some syntactic sugar to
    make specifying address-to-name queries easier.
    
    For example --rev-server=1.2.3.0/24,192.168.0.1 is exactly equivalent to
    --server=/3.2.1.in-addr.arpa/192.168.0.1
