There are a few ways you can change your IP address on macOS. Before you dive into the system settings, though, try resetting your router. This should assign you a new IP address automatically. If this seems like too much work, you can connect to a VPN app, or follow the steps below to manually refresh your IP address:
Open the menu by clicking the Apple icon
Select System Preferences, then Network
Choose your network in the list, then click the Advanced button
Open the TCP/IP section and click Renew DHCP Lease
That’s it – you should now be browsing with a completely new IP address
