On a Mac computer you can send a ping using the Terminal or through the Network Utility application. Using the Terminal to Send a Ping The terminal is a command line interface that can be used for all kinds of things, including for sending a ping. Colasoft MAC Scanner is used for scanning IP address and MAC address. It can automatically detect all subnets according to the IP addresses configured on multiple NICs of a machine and scan the MAC addresses and IP addresses of defined subnets. I've tried a bevy of network tools like Look@LAN but none of them discover the WAP. Ping by MAC Address. The answer to the question is you cannot ping by a MAC address unless the device is. Nping is an open source tool for network packet generation, response analysis and response time measurement. It is free and open source and runs on Linux, *BSD, Windows and Mac OS X. TCP/IP computer networks use both the IP addresses and MAC addresses of connected client devices. While the IP address changes over time, the MAC address of a network adapter always stays the same.

Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It is available for virtually all operating systems that have networking capability, including most embedded network administration software.
Ping measures the round-trip time for messages sent from the originating host to a destination computer that are echoed back to the source. The name comes from active sonar terminology that sends a pulse of sound and listens for the echo to detect objects under water.[1]https://gatorsite.weebly.com/blog/optimization-tool-for-mac.
Ping operates by sending Internet Control Message Protocol (ICMP) echo request packets to the target host and waiting for an ICMP echo reply. The program reports errors, packet loss, and a statistical summary of the results, typically including the minimum, maximum, the mean round-trip times, and standard deviation of the mean.
The command-line options of the ping utility and its output vary between the numerous implementations. Options may include the size of the payload, count of tests, limits for the number of network hops (TTL) that probes traverse, and interval between the requests. Many systems provide a companion utility ping6, for testing on Internet Protocol version 6 (IPv6) networks, which implement ICMPv6.

History[edit]
The ping utility was written by Mike Muuss in December 1983 during his employment at the Ballistic Research Laboratory, now the US Army Research Laboratory. Created as a tool to troubleshoot problems in an IP network, Mike Muuss was inspired by a remark by David Mills on using ICMP echo packets for IP network diagnosis and measurements.[2] The author named it after the sound that sonar makes, since its methodology is analogous to sonar's echo location.[1][3] The first released version was public domain software while all subsequent versions were licensed under the BSD license. Ping was first included in 4.3BSD.[4] The FreeDOS version was developed by Erick Engelke and is licensed under the GPL.[5] Tim Crawford developed the ReactOS version. It is licensed under the MIT License.[6]
RFC 1122 prescribes that any host must process ICMP echo requests and issue echo replies in return.[7]
Invocation example[edit]
The following is the output of running ping on Linux for sending five probes to the target host www.example.com:
The output lists each probe message and the results obtained. Finally it lists the statistics of the entire test. In this example, the shortest round trip time was 9.674 ms, the average was 10.968 ms, and the maximum value was 11.726 ms. The measurement had a standard deviation of 0.748 ms.
Error indications[edit]
In cases of no response from the target host, most implementations display either nothing or periodically print notifications about timing out. Possible ping results indicating a problem include the following:
- H,!N or !P â host, network or protocol unreachable
- S â source route failed
- F â fragmentation needed
- U or !W â destination network/host unknown
- I â source host is isolated
- A â communication with destination network administratively prohibited
- Z â communication with destination host administratively prohibited
- Q â for this ToS the destination network is unreachable
- T â for this ToS the destination host is unreachable
- X â communication administratively prohibited
- V â host precedence violation
- C â precedence cutoff in effect
In case of error, the target host or an intermediate router sends back an ICMP error message, for example 'host unreachable' or 'TTL exceeded in transit'. In addition, these messages include the first eight bytes of the original message (in this case header of the ICMP echo request, including the quench value), so the ping utility can match responses to originating queries.[8]

Generic composition of an ICMP packet:[9]https://gatorsite.weebly.com/blog/eve-fit-tool-for-mac.
- IPv4 Header (in blue): protocol set to 1 (ICMP) and Type of Service set to 0.
- IPv6 Header (in blue): Next Header set to 58 (ICMP6)
- ICMP Header (in red):
- Type of ICMP message (8 bits)
- Code (8 bits)
- Checksum (16 bits), calculated with the ICMP part of the packet (the IP header is not used). It is the 16-bit one's complement of the one's complement sum of the ICMP message starting with the Type field[10]
- Header Data (32 bits) field, which in this case (ICMP echo request and replies), will be composed of identifier (16 bits) and sequence number (16 bits).
- ICMP Payload: payload for the different kind of answers; can be an arbitrary length, left to implementation detail. However, the packet including IP and ICMP headers must be less than the maximum transmission unit of the network or risk being fragmented.
Echo request[edit]
The echo request ('ping') is an ICMP/ICMP6 message.
00 | 01 | 02 | 03 | 04 | 05 | 06 | 07 | 08 | 09 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 |

Type = 8(IPv4, ICMP) 128(IPv6,ICMP6) | Code = 0 | Checksum | |||||||||||||||||||||||||||||
Identifier | Sequence Number | ||||||||||||||||||||||||||||||
Payload |
The Identifier and Sequence Number can be used by the client to match the reply with the request that caused the reply. In practice, most Linux systems use a unique identifier for every ping process, and sequence number is an increasing number within that process. Windows uses a fixed identifier, which varies between Windows versions, and a sequence number that is only reset at boot time.
Echo reply[edit]
The echo reply is an ICMP message generated in response to an echo request; it is mandatory for all hosts, and must include the exact payload received in the request.
00 | 01 | 02 | 03 | 04 | 05 | 06 | 07 | 08 | 09 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 |

Identifier | Sequence Number | ||||||||||||||||||||||||||||||
Payload |

- The identifier and sequence number can be used by the client to associate each echo request with its reply.
Payload[edit]
The payload of the packet is generally filled with ASCII characters, as the output of the tcpdump utility shows in the last 32 bytes of the following example (after the eight-byte ICMP header starting with 0x0800):
The payload may include a timestamp indicating the time of transmission and a sequence number, which are not found in this example. This allows ping to compute the round trip time in a stateless manner without needing to record the time of transmission of each packet.
Free Ping Tools
The payload may also include a magic packet for the Wake-on-LAN protocol, but the minimum payload in that case is longer than shown. The Echo Request typically does not receive any reply if the host was sleeping in hibernation state, but the host still wakes up from sleep state if its interface is configured to accept wakeup requests. If the host is already active and configured to allow replies to incoming ICMP Echo Request packets, the returned reply should include the same payload. This may be used to detect that the remote host was effectively woken up, by repeating a new request after some delay to allow the host to resume its network services. If the host was just sleeping in low power active state, a single request wakes up that host just enough to allow its Echo Reply service to reply instantly if that service was enabled. The host does not need to completely wake up all devices, and may return to low power mode after a short delay. Such configuration may be used to avoid a host to enter in hibernation state, with much longer wake up delay, after some time passed in low power active mode.[citation needed]
Security considerations[edit]
To conduct a denial-of-service attack, an attacker may send ping requests as fast as possible, possibly overwhelming the victim with ICMP echo requests. This technique is called a ping flood.
Ping requests to multiple addresses, ping sweeps, may be used to obtain a list of all hosts on a network.
