To change the IP address on a Windows computer, you can either configure a static IP address manually or allow the system to obtain an IP address automatically via DHCP. The process involves adjusting network adapter settings through the Control Panel or Settings app.

Begin by opening the Network and Sharing Center or navigating to Network & Internet settings. From there, select the appropriate network adapter, such as Ethernet or Wi-Fi, and access its properties.

To manually set a static IP address, follow these steps:

  • Open the adapter’s properties and select “Internet Protocol Version 4 (TCP/IPv4).”
  • Click the Properties button.
  • Choose “Use the following IP address.”
  • Enter the desired IP address, subnet mask, and default gateway.
  • Optionally, specify DNS server addresses or choose to obtain them automatically.
  • Confirm the changes and close the dialog boxes.

If you want the IP address to be assigned automatically:

  • Select “Obtain an IP address automatically” and “Obtain DNS server address automatically” in the TCP/IPv4 properties.
  • Save the settings to enable DHCP.

This process can also be performed via the Command Prompt using the `netsh` utility for advanced users who prefer command-line operations.

Setting Description Example
IP Address The unique address assigned to your computer on the network 192.168.1.100
Subnet Mask Defines the network portion of the IP address 255.255.255.0
Default Gateway The router IP address that allows communication outside the local network 192.168.1.1
DNS Server Resolves domain names to IP addresses 8.8.8.8 (Google DNS)

Changing the IP Address on macOS

On macOS, changing the IP address is managed through the Network Preferences pane. This allows you to configure either a dynamic or static IP address depending on your network requirements.

To set a static IP:

  • Open System Preferences and select Network.
  • Choose the active network interface (e.g., Wi-Fi or Ethernet).
  • Click the “Advanced” button and navigate to the TCP/IP tab.
  • From the “Configure IPv4” dropdown, select “Manually.”
  • Enter the desired IP address, subnet mask, and router (gateway) address.
  • Click OK and then Apply to save the settings.

For dynamic IP address allocation, select “Using DHCP” in the “Configure IPv4” dropdown. The system will then obtain an IP address automatically from the network’s DHCP server.

Additional options include renewing the DHCP lease if you want to refresh the current IP address without setting a static one. This can be done within the same TCP/IP tab by clicking “Renew DHCP Lease.”

Changing the IP Address on Linux

Linux systems provide several ways to change the IP address, including graphical user interfaces for desktop environments and command-line tools for servers or minimal installations.

  • Select either “Manual” to enter a static IP or “Automatic (DHCP)” for dynamic assignment.
  • Fill in the IP address, subnet mask (netmask), gateway, and DNS servers if setting manually.
  • Save and apply the changes.

Using the command line, the `ip` command or `ifconfig` can be used (though `ifconfig` is deprecated in many distributions):

“`bash
sudo ip addr add 192.168.1.100/24 dev eth0
sudo ip route add default via 192.168.1.1
“`

To remove an existing IP address before adding a new one:

“`bash
sudo ip addr del 192.168.1.50/24 dev eth0
“`

Alternatively, `nmcli` (Network Manager command-line interface) can be used to modify connections persistently.

Command Purpose Example
ip addr add Add an IP address to a network interface sudo ip addr add 192.168.1.100/24 dev eth0
ip addr del Remove an IP address from a network interface sudo ip addr del 192.168.1.50/24 dev eth0
ip route add Add a default gateway route sudo ip route add default via 192.168.1.1

When changing IP addresses, it is important to ensure that the new address does not conflict with other devices on the network and that the subnet mask and gateway are correctly configured to maintain connectivity.

Changing the Computer IP Address on Windows

To change the IP address on a Windows computer, you can either set a static IP address or allow the system to obtain one automatically via DHCP. The following steps outline how to manually configure a static IP address.
