🔄 How to Renew Your IP Address in Windows and Linux

Whether you’re troubleshooting network issues or just want a fresh IP lease, renewing your IP address is a quick way to reset your connection. Here’s how to do it on both Windows and Linux systems.

🪟 Windows: Renew IP via Command Prompt

✅ Steps:

• Open Command Prompt as Administrator
• Release the current IP address:

ipconfig /release

• Renew the IP address:

ipconfig /renew

• Check your new IP address:

ipconfig

💡 Tip: To target a specific adapter, use:
ipconfig /renew "Ethernet"

🐧 Linux: Renew IP via Terminal

🔧 Method 1: Using dhclient

sudo dhclient -r
sudo dhclient
  

Add -v for verbose output:
sudo dhclient -v -r eth0
sudo dhclient -v eth0

🔧 Method 2: Using nmcli (NetworkManager)

nmcli con down id "MyConnection"
nmcli con up id "MyConnection"
  

🔧 Method 3: Using dhcpcd (Raspbian, etc.)

sudo dhcpcd -k eth0
sudo dhcpcd -n eth0
  

⚠️ Avoid running these over SSH unless you’re using a timed script or at job.
You can also restart the network service:
sudo systemctl restart networking.service
