Some parameter descriptions:

Listen-on Port: (any;}   This is the listening port, the default is to listen only local, I changed to any.   Directory This is the zone's access directory Dump-file Statistics-file memstatistics-file These three are statistical files, generally without modification, the default is available. Allow-query {Any} This parameter is very important, my understanding is to allow reply to where the request, the default is local, I here to modify into any of the bottom three DNS beginning of the file, the default is the zone file configuration, we need to set two zone, a positive solution, a Inverse solution. There is also a zone of the default type hint. Never delete this zone ".".   This is the resolution of DNS other than the native setting DNS.   Zone settings are simple, reference to write can be, it should be noted that the anti-solution zone name of the writing.   Watch the Zone "168.192.in-addr.arpa". My intranet IP address is 192.168.0.107. Anti-write is: 0.0.168.192. If the address is 1 paragraphs, for example, 192.168.1.0/24, the reverse is 0.1.168.192.      The previous 0 does not write 1.168.192. Configuration of the 4./var/named zone file
