Instalación:

Lo primero de todo vamos a configurar la zona directa

-sudo apt install -y bind9

- sudo systemctl status named

-sudo nano /etc/bind/named.conf.local

zone "aulaSMR118.local" {
type master;
file "/etc/bind/db.aulaSMR118.local";
};

-sudo nano /etc/bind/db.aulaSMR118.local

sudo systemctl reload named

Comprobación zona directa:

-nslookup ai1pc118.aulaSMR118.local localhost
-nslookup ai1pc100.aulaSMR118.local localhost

Ahora vamos a configurar la zona inversa:

sudo nano /etc/bind/named.conf.local

zone "118.28.172.in-addr.arpa" {
type master;
file "/etc/bind/db.118.28.172";
};

sudo nano /etc/bind/db.118.28.172
