DN42入坑指南（四）基于powerdns配置IP反向解析

规划

#将属于我自己的IP段儿配置反向解析（172.20.58.192/27）

#反向解析的区域名字：192/27.58.20.172.in-addr.arpa

172.20.58.193   IN PTR  as4242420524-la.wsfnk.dn42
172.20.58.194   IN PTR  as4242420524-hk.wsfnk.dn42
172.20.58.195   IN PTR  as4242420524-cq.wsfnk.dn42
172.20.58.196   IN PTR  as4242420524-sj.wsfnk.dn42
172.20.58.197   IN PTR  as4242420524-gb.wsfnk.dn42
172.20.58.198   IN PTR  as4242420524-bj.wsfnk.dn42
