ラズベリーパイでDNSサーバ4

ソフトをインスト-ル

# apt -y install bind9 bind9utils

設定ファイルを書き換える。

# vi /etc/bind/named.conf

以下の文字の後に追加

include "/etc/bind/named.conf.default-zones";
include "/etc/bind/named.conf.internal-zones";

# vi /etc/bind/named.conf.options

acl internal-network {
        192.168.2.0/24;
};

        allow-query { localhost; internal-network; };
         recursion yes;
//=======================================================================

         dnssec-validation auto;
         listen-on-v6 { any; };

ローカルネットワークの定義をする

# vi /etc/bind/named.conf.internal-zone

zone "hibiki.serveblog.net" IN {
        type master;
        file "/etc/bind/hibiki.serveblog.net.lan";
        allow-update { none; };
};

zone "amamoto-music.sytes.net" IN {
        type master;
        file "/etc/bind/amamoto-music.sytes.net.lan";
        allow-update { none; };
};

zone "hibiki-cloud.ddns.net" IN {
        type master;
        file "/etc/bind/hibiki-cloud.ddns.net.lan";
        allow-update { none; };
};

zone "2.168.192.in-addr.arpa" IN {
        type master;
        file "/etc/bind/2.168.192.db";
        allow-update { none; };
};

名前解決でIPv4（Ver.4は）使い倒すけど新規格IPv6（Ver.6）は使うので次の設定を確認する。

# vi /etc/default/named

OPTIONS="-u bind"
