Ping from Source IP Address from all environments

In this article, we shall discuss the various steps on how to Ping from Source IP Address from all environments. Ping is a network diagnostic utility employed to test the reachability of a device (host), and network appliances on an Internet Protocol (IP) network. Please see how to Analyse Disks with Treesize: Defragment and Shrink VMware Workstation VM Disks, and how to Map and disconnect Virtual Disk in VMware Workstation.

Ping measure the time it takes for packets which are small chunks of data to travel from the source (your device) to a destination (another device on the network or the internet) and back again.

In addition to determining network reachability, which is crucial for troubleshooting. The ping utility helps measure latency, revealing the delay between two devices.

Ping also detects packet loss, allowing us to identify network congestion or potential issues when some packets fail to reach their destination. Below are the key concept of what Ping does:

• Echo Request and Echo Reply: Ping sends an ICMP (Internet Control Message Protocol) Echo Request to the target device. If the target device is reachable and responding, it sends back an ICMP Echo Reply.
• Latency Measurement: This is the time it takes for the request to reach the target and for the reply to return. This phenomenon is referred to as latency or round-trip time (RTT). This is usually measured in milliseconds (ms).
• Packet Loss: Ping also helps detect packet loss, which occurs when some packets fail to reach the destination or return, indicating network congestion or problems.
• Hop Count: Sometimes, Ping can give you an idea of the number of network hops (routers) between the source and the destination. Although for this specific information, the traceroute is more commonly used for determining the number of hops.

Why Perform Ping specifically from a Source IP?

Pinging from a specific source IP is useful in network troubleshooting, testing, and diagnostics as discussed above. Below are ome reasons why you might want to ping from a specific source IP Address.

• By specifying a source IP, you can check if traffic from that IP address can reach the destination. This is vital when the network involves multiple interfaces or paths, and you want to confirm which route is used.
• If a system has multiple network interfaces (e.g., Ethernet and Wi-Fi) or virtual network interfaces. You might want to test connectivity from a specific interface by specifying the corresponding source IP.
• A lot of firewalls and routers apply rules based on source IP addresses. By pinging from a specific source IP, you can verify if traffic from that IP address is allowed or blocked by the firewall or if the routing works as expected for that IP.
• In a setup where traffic is load-balanced or uses failover configurations. Pinging from different source IPs helps ensure that each IP address is routed correctly through the intended interface or server.
• For systems that expect requests from specific IP addresses (due to security policies, Access Control Lists (ACLs) used for filtering, or NAT rules). Pinging from a designated source IP helps to verify if the destination is accessible from that particular source.

Ping from Source IP Address from all environments

For Windows

Continuous ping can be realized in the following ways. Open command Prompt and type the command ‘ping’ followed by the IP Address and followed by ‘-t’ flag

Ping -t 192.168.2.1 
ping 192.168.2.1 -t 

Ping 8.8.8.8 -i <your ip address>

Note: The -I option specifies the source IP address or network interface to use when sending the ping. This is useful if you have multiple network interfaces (e.g., Ethernet, Wi-Fi) or multiple IP addresses assigned to your system. And you want to control which interface is used for the ping.

Below are the components of a Ping Response.

• Reply from [IP]: Indicates that the destination responded successfully.
• Bytes=32: The size of the ICMP packet sent and received.
• Time=XXms: The round-trip time for the packet, indicating network latency.
• TTL (Time to Live): The number of hops (routers) the packet can pass through before being discarded.

Perform Ping from Source IP Address via PowerShell

Replace <Source-IP> and <Destination-IP> with the desired IP addresses. Third-Party Tools such as hping3 or nping (from the Nmap suite) allow more advanced ping options, including setting the source IP.

Test-Connection -Source <Source-IP> -ComputerName <Destination-IP>

Please see how to stop an application from starting up automatically on macOS. Also, see “Why am I unable to ping the Public IP Address of an EC2 instance“.

Perform Ping on Mac OSX

In both Linux and macOS, you can use the ping command with the -I option to specify the source interface or IP address.

By default, this is continuous as shown below. Just type ping following by the IP or FQDN

Ping 192.168.2.1 or Ping google.com

Note: If this is also not continuous by default, simple run it this way for MacOSX

/sbin/ping 192.168.2.1

Alternatively, you could use specify a specific interface or source IP with the command below.

ping -I <Source-IP> <Destination-IP>

This command also works for Linux devices. This will be in this form “ping -I 192.168.1.100 8.8.8.8“. This will send ping requests to Google’s DNS (8.8.8.8) from the IP address 192.168.1.100.

For Linux

This is also continuous by default. Simply type as shown below

ping 192.168.1.1 

High count rate can also be indicated for a long period of time. See example below. This example will ping  about 333 times.

ping 192.168.1.1 -c 333

If this continuous ping does not work by default, there is probably an alias for the ping command which is changing the way you invoke the ping utility.
Solution: Find where the ping command is using the command below.

which ping

Next call the ping program from the path and it should be continuous.

/bin/ping 192.168.2.1

For Juniper: This is by default as well. Simply run 

ping 192.168.2.1

hping3 (Linux/Unix): hping3 is another tool for more control over packet crafting, including specifying source IP.

hping3 -a <Source-IP> <Destination-IP>

Advanced Tools (All Platforms):

nping (Nmap suite): nping is a tool that allows you to specify source IP and other advanced options

nping --source-ip <Source-IP> <Destination-IP>

For Cisco Devices

Network troubleshooting and diagnostic tasks use these methods to verify connectivity, routing, or firewall rules when multiple network interfaces or IP addresses are involved.

Continuous ping is not possible on devices like ASA, switches, and routers. But it can be repeated as shown below.

ping 192.168.2.1 repeat 333

If this repeat command does not work, simple enter the ping command and should the help function along side.
