What is IPv4?
IPv4 (Internet Protocol Version 4) is the most widely used form of an IP address. The IPv4 addresses are 32-bits long and use DNS A records to map the hostname to an IP address.
The IPv4 was the first kind of IP created in networking. They are short in number, and the maximum available to be ever assigned to devices is 4,294,967,296.
Ping (Packet InterNet Groper) is a computer network administration utility that helps one to check whether a particular IP address or domain is accessible on the computer network or not. Ping works by sending a packet to a provided address and waiting for the reply. It also measures round trip time and reports errors.
The Ping tool uses the Internet Control Message Protocol (ICMP) Echo function detailed in RFC792. A small packet will be sent to the given IPv4 address. The packet contains 64 bytes, 56 data bytes, and 8 bytes of protocol reader information.
Ping works by sending ICMP "echo request" (ping) packets to the target host and listening for ICMP "echo response" (pong) replies. Per RFC1122, "Requirements for Internet Hosts," each host must send an echo reply when pinged.
