【bind】messagesにRFC 1918 response from Internet for xxx.xxx.xxx.xxx.in-addr.arpaのログが出力される件

ログの意味

RFC 1918 response from Internet for xxx.xxx.xxx.xxx.in-addr.arpa

xxx.xxx.xxx.xxx.in-addr.areaに対応するDNSゾーンが定義されていない場合にログが出力されている模様。
ログを一見すると、InternetにプライベートIPアドレスが漏れているよって見えるけど、
必ずしもそういう意味ではない?

解決方法

/etc/named.confに対応するDNSゾーンファイルを作成してあげましょう。

/etc/named.conf
zone "xxx.xxx.in-addr.arpa." {
                type master;
                file "xxx.xxx.rev";
        };

これをnamedに反映してあげれば、ログが出力されなくなります。
