Install DNS Server Debian 12

Pastikan server sudah mendapatkan ip address. Cek dengan cara mengetikan

#ip a (enter)

Jika sudah muncul tampilan berikut, artinya sudah mendpatkan ip address

root@latdns:~# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0@if114: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether 76:69:11:b8:38:cd brd ff:ff:ff:ff:ff:ff link-netnsid 0
    inet 192.168.20.9/24 brd 192.168.20.255 scope global dynamic eth0
       valid_lft 1717sec preferred_lft 1717sec
    inet6 fe80::7469:11ff:feb8:38cd/64 scope link 
       valid_lft forever preferred_lft forever
root@latdns:~# 

Lalu cek koneksi internet dengan mengetikkan perintah

#ping google.com (enter)

Jika muncul tampilan seperti ini artinya sudah ada koneksi internet
