现在有一个需求需要在dns中对dbprod126建一个别名wondadb3r的记录也就是ping wondadb3r的时候显示的是dbprod126的ip目前有两种方法主要使用方法1指向别名因为使用方法1的时候如果dbprod126更改了ip以后ping wondadb3r也会显示更改后的ip 方法1指向别名在dns中建立wondadb3r指向服务器dbprod126结果类似图中name为DWPROD2R的记录 方法2指向ip在dns中建立wondadb3r指向ip 172.22.100.4结果类似图中name为DWdbalias的记录 方法1的ping结果dwprod2r和dbprod83指向通一个ip但是ping dwprod2r时显示的是dbprod83
