Changing an IP address in Windows 10 can mean renewing a router-assigned private address or configuring a static local address. Use DHCP unless you have a specific networking reason and know the correct network values.
Steps
- For a normal DHCP connection, disconnect and reconnect the network first when you simply need a fresh connection.
- For a command-line renewal, open an authorized Command Prompt and use ipconfig /release followed by ipconfig /renew.
- To configure a static address, open the network adapter’s IP assignment or IPv4 properties.
- Choose manual IPv4 only when you know the correct IP address, subnet, gateway, and DNS values.
- Use an unused address valid for that network and avoid conflicts with DHCP reservations or other devices.
- Test local network and Internet access.
- Return to Automatic (DHCP) if the manual configuration causes problems.
Private and public IP addresses are different
Your router or ISP normally controls the public Internet address seen by websites. Changing the PC’s private LAN address does not necessarily change the public address.
Static addresses can cause conflicts
Assigning an address already used by another device can interrupt connectivity for both systems. On managed networks, use the administrator’s addressing plan.
DNS is a separate setting
Changing an IP address does not require changing DNS servers unless the network configuration calls for it. Incorrect DNS can make websites appear unreachable even when basic network connectivity works.
Windows 10 is unsupported
Windows 10 reached the end of standard support in October 2025. Network configuration still functions, but Internet-connected PCs should migrate to a supported operating system.
