Renew your IP address from the DHCP server on Mac (1)

If you receive your IP address using DHCP, you can force your computer to renew your current IP address. In some cases, renewing the IP address resolves connection issues.

You might need to do this periodically in an environment where many computers use the same DHCP server or the network administrator has set up a short DHCP lease time.

Check with your ISP or network administrator to find out whether you need to renew your DHCP address.

On your Mac, choose Apple menu >System Settings, then click Network in the sidebar. (You may need to scroll down.)
Open Network settings for me
Click the network service that needs a renewed IP address on the right, then click Details.
Click TCP/IP, then click Renew DHCP Lease.
Click OK.
