+# Configurare IP address Debian 12
+
+Verificare quale è il nome della rete
+
+```sh
+ip a
+```
+
+dalla risposta si evince che la rete è ***enP3p49s0***
+
+```sh
+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 noprefixroute 
+       valid_lft forever preferred_lft forever
+2: enP3p49s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
+    link/ether c0:74:2b:fc:61:b7 brd ff:ff:ff:ff:ff:ff
+    inet 192.168.1.4/24 brd 192.168.1.255 scope global dynamic noprefixroute enP3p49s0
+       valid_lft 32132sec preferred_lft 32132sec
+    inet6 fe80::70da:ae13:b91c:cf72/64 scope link noprefixroute 
+       valid_lft forever preferred_lft forever
+3: enP4p65s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
+    link/ether c0:74:2b:fc:61:b6 brd ff:ff:ff:ff:ff:ff
+```
+
+editando il file /etc/network/interfaces
+
+```console
+sudo nano /etc/network/interfaces
+```
+
+va scritto come
+
+ ```sh
+auto <interface_name>
+iface <interface_name> inet static
+   address <your_static_ip>/<subnet_mask_bits>
+   gateway <your_gateway_ip>
+   dns-nameservers <your_dns_server(s)>
+```
+con i seguenti campi
+
+```sh
+<interface_name> is the name of your network interface.
+<your_static_ip> is the desired static IP address.
+<subnet_mask_bits> is the subnet mask represented as bits (e.g., /24 for 255.255.255.0).
+<your_gateway_ip> is the IP address of your gateway router.
+<your_dns_server(s)> are the IP addresses of your DNS servers, separated by spaces. 
+```
+quindi nel nostro caso va aggiunto (qui ho usato dns di google)
+```sh
+auto enP3p49s0
+iface enP3p49s0 inet static
+   address 192.168.1.4/24
+   gateway 192.168.1.1
+   dns-nameservers 8.8.8.8 8.8.4.4
+```
+
+
+### Applying Network Configuration Changes
+
+After editing your network configuration files, apply the changes using the ifup and ifdown commands. These commands deactivate and reactivate your network interface, respectively.
+```sh
+sudo ifdown enP3p49s0 && sudo ifup enP3p49s0
+```
+For the new network settings to take effect, you may also restart the networking service entirely.
+```sh
+sudo systemctl restart networking
+```
