macOS - Displaying, Releasing, and Renewing a DHCP Lease

The following instructions will walk you through how to:
  • Display the network settings currently assigned. This information can be utilized to verify whether or not a network connection exists as well as what your network settings are.
  • Release the current DHCP configuration. Note: Releasing allows you to discard the current configuration settings (such as the IP address) which have been assigned to you.
  • Renew the DHCP configuration. Renewing will pull a new IP address lease from the DHCP host and in many cases resolves connection issues.
  1. On your Mac, choose the Apple menu > System Settings, then click Network in the sidebar. (You may need to scroll down.)
  2. Click the network service that needs a renewed IP address, then click Details.
  3. Click TCP/IP, then click Renew DHCP Lease.
  4. Click OK.
