What do the ping fields mean?
- bytes — Size of the ICMP echo reply payload (usually 56–64 bytes).
- icmp_seq — Sequence number, increments each packet. Gaps indicate dropped packets.
- ttl — Time To Live: how many router hops the packet survived. Subtract from the OS default (Linux=64, Windows=128, Cisco=255) to estimate hop count.
- time — Round-trip latency in milliseconds. Under 20ms is excellent; over 150ms feels laggy for interactive use.
- packet loss — Percentage of packets that did not return. Any loss above 0% warrants investigation.
