Update the public IP address to reflect the new location or configuration.
You seem to be misunderstanding the concepts. Each network interface has its own MAC address, but they don't all share the same one. When data travels, it carries its own source and destination MAC addresses. The receiving device unpacks the packet, swaps out the source address with its own, and sends it forward with a new destination address. All traffic destined for the ISP stays under the router's MAC, which acts as a unique ID to allocate a connection. TTL stands for Time to Live, indicating how many times a packet can hop before being discarded to avoid loops in the IP layer. DHCP assigns lease times, not TTL, and when the timer reaches half its value, the device requests a refresh from the server.

More knowledgeable? If he truly understood, he’d grasp the concept of TTL on lease duration. When that link is severed, the TTL vanishes immediately. It’s a matter of ignorance—he understands everything about IPv4, MAC addresses, and DHCP. Yet he lacks precise technical vocabulary. In short, he can reach out to his ISP for guidance and education. He appears difficult to contact.
