Renewing your IP address frequently fixes minor glitches and connectivity issues. Your Mac will ask your DHCP server—frequently your Wi-Fi router—for the new IP address and interface using either a similar one or the new one, contingent upon the details your router provides
IP Address versus MAC Address
An IP Address is used to identify a computer on the Internet or a local intranet. On the off chance that computers share a particular local network, every one of the computers will likewise share a piece of their IP Address. As such, the comparative IP Addresses may demonstrate that a PC is close. The accompanying model represents what an (IP v4) IP Address may resemble:
The Media Access Control (MAC) Address is used to identify Ethernet network cards or basically PCs that have built-in Ethernet. In other words, every computer that uses Ethernet will have a MAC address; in any case, recollect that some Internet associations don’t use Ethernet. Not at all like the IP Addresses, computers that share a particular local network won’t have MAC addresses that take after each other in any capacity.
To discover these settings, click the “Apple” symbol in the upper-right corner of the menu bar, and select “System Preferences.”
Click “Network” in the System Preferences window.
Pick a suitable network and click the “advanced” button. This works with both wired (Ethernet) and remote (Wi-Fi) associations.
The next screen should default to the Wi-Fi tab. Pick “TCP/IP” all things considered, just to the right of it.
Click the “Renew DHCP License” catch and afterward click “Ok” when the renewal is finished. Clicking this catch instructs your Mac to get new routing information from the DHCP Sarver.
Resetting this could improve your Mac’s connectivity, particularly on the off chance that you’ve recently changed router settings.
