A traceroute shows the path a packet takes from your device to a target, listing each router (hop) along the way with round-trip time (RTT). Each line is one hop. Look for: (1) an unexpected jump in RTT — usually indicates a congested link or geographic detour; (2) * * * responses — hop isn’t responding to traceroute (may be firewalled but still forwarding); (3) the final hop’s RTT — total end-to-end latency to the target. Use the visual traceroute tool for a mapped visualization with hop geo-location. Common patterns: 1-3 hops = your ISP, 3-8 = transit ISPs, 8+ = destination’s network.

What Is a MAC Address?
MAC addresses are the physical-layer identifiers that let switches and Wi-Fi access points route Ethernet frames. Every network interface has one, burned in at manufacture. Modern devices randomize MACs to defeat cross-network tracking.
