Here are the major options for ping command.
-n Count Determines the number of echo requests to send. The default is 4 requests.
-w Timeout Enables you to adjust the time-out (in milliseconds). The default is 1,000 (a 1-second time-out).
-l Size Enables you to adjust the size of the ping packet. The default size is 32 bytes.
-f Sets the Do Not Fragment bit on the ping packet. By default, the ping packet allows fragmentation
So if you want ping to run for a long time or theoretically infinite, give an infinite value for the count parameter in the “-n” flag
ping -n 2000000000 <Host IP>
OR
ping -t <Host IP>
Also the “-w” can be used to increase the timeout for which the ping command waits for the return of the packet.
