Study Notes

Ping Utility

The ping utility is a network tool that sends ICMP Echo request packets to a remote host and receives ICMP Echo response packets.
Successful pinging indicates both physical connectivity and properly configured protocols between a workstation and the remote host.
ICMP Echo request packet size is displayed in bytes.
Time taken for a packet to travel round-trip is recorded.
Pinging can reveal loss of packets, which can indicate network congestion, hardware issues, or other problems.

Using Ping

Pinging can be done by IP address or by hostname.
If a host can be pinged by IP address but not by hostname, name resolution may be the issue.

Pinging on Different Subnets

Pinging hosts on the same subnet typically results in fast round trip times due to minimal distance.
Pinging hosts on different subnets within the same organization will require travel through routers.
Pinging hosts on the internet will require travel through at least two organizational routers and then through multiple internet routers.
The round trip time for internet pings will typically be significantly slower due to greater distance.
