Bind9 -“标签太长”

Question

是否有任何方法可以增加pri.example.com文件中子域(A记录)的长度，以便Bind9可以加载一个长子域，而无需显示“标签太长”，例如：

this-is-a-subdomain-number-one   $ATTL IN A XXX.XXX.XXX.XXX
this-is-a-subdomain-number-two   $ATTL IN A XXX.XXX.XXX.XXX
this-is-a-subdomain-number-three-that-one-of-my-clients-wish-to-use-for-his-website-but-bind9-upon-loading-is-displaying-label-to-long-error   $ATTL IN A XXX.XXX.XXX.XXX
this-is-a-subdomain-number-four   $ATTL IN A XXX.XXX.XXX.XXX

this-is-a-subdomain-number-one.example.com，this-is-a-subdomain-number-two.example.com和this-is-a-subdomain-number-four.com工作正常，但bind9不能加载this-is-a-subdomain-number-three-that-one-of-my-clients-wish-to-use-for-his-website-but-bind9-upon-loading-is-displaying-label-to-long-error.example.com：

有什么想法吗？

从‘百科’

Each label may contain up to 63 characters. The full domain name may not exceed the length of 253 characters in its textual representation. In the internal binary representation of the DNS the maximum length requires 255 octets of storage, since it also stores the length of the name.
