OS X Mavericks: Renew an IP address from the DHCP server
If you are set up to receive your IP address using DHCP, you can force your computer to renew your current IP address.
This might be helpful 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.
- Choose Apple menu > System Preferences, then click Network.
- Select your connection service that uses DHCP in the list (such as Ethernet or Wi-Fi).
- Click Advanced, click TCP/IP, then click Renew DHCP Lease.
