BIND 9.9 起，Slave zone 檔案內定為二進位格式
修改 /etc/named.conf
加上 masterfile-format text; 即可
例如
zone "abc.com.tw" {
type slave;
file "named.abc.com.tw";
masterfile-format text;
masters { 107.167.1.1; };
};
另外，將 二進位 zone 檔案 轉成文字檔的方式：
named-compilezone -f raw -F text -o named.abc.com.tw.txt abc.com.tw named.abc.com.tw
* named.abc.com.tw 二進位檔
* named.abc.com.tw.txt 匯出的文字檔
如何查詢 Bind 版本
$ nslookup -q=txt -class=chaos version.bind 103.29.xx.xx
Server: 103.29.xx.xx
Address: 103.29.xx.xx#53
version.bind text = "9.9.4-RedHat-9.9.4-29.el7_2.4"
$ dig txt chaos version.bind @103.29.xx.xx
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.47.rc1.el6_8.1 <<>> txt chaos version.bind @103.29.70.73
