How to set static IP in kali linux?

Step 1: Run as root user

┌──(kali㉿kali)-[~]
└─# sudo su

┌──(root㉿kali)-[~]
└─# 

Step 2: Check your current IP configuration

┌──(root㉿kali)-[~]
└─# ifconfig

eth0    inet6  fe80::250:xxxx:xxxx:xxxx  ...  ...  ...

Step 3: Change eth0’s IP address

┌──(root㉿kali)-[~]
└─# ifconfig eth0 10.10.10.2

┌──(root㉿kali)-[~]
└─# ifconfig

eth0    inet  10.10.10.2  netmask 255.0.0.0  broadcast  10.255.255.255

OR

┌──(root㉿kali)-[~]
└─# ifconfig eth0 10.10.10.2 netmask 255.255.255.0 up

┌──(root㉿kali)-[~]
└─# ifconfig

eth0    inet  10.10.10.2  netmask 255.255.255.0  broadcast  10.255.255.255

Step 4: if you need to assign a default gateway

┌──(root㉿kali)-[~]
└─# route add default gw 10.123.123.1

┌──(root㉿kali)-[~]
└─# ifconfig

eth0    inet  10.10.10.2  netmask 255.255.255.0  broadcast  10.255.255.255

┌──(root㉿kali)-[~]
└─# route

Destination  Gateway        Genmask    Flags  ...  IFace
default      10.123.123.1    ...        ...   ...  eth0

Step 5: if you need to add a DNS server

┌──(root㉿kali)-[~]
└─# nano /etc/resolv.conf

┌──(root㉿kali)-[~]
└─# cat /etc/resolv.conf

# Generated by NetworkManager
search localdomain
nameserver  8.8.8.8

Step 6: Test Ping with your target IP address

┌──(root㉿kali)-[~]
└─# ping 10.10.10.3
