The packet contains 64 bytes, 56 data bytes, and 8 bytes of protocol reader information. A small packet will be sent to the given IPv4 address. The Ping tool uses the Internet Control Message Protocol (ICMP) Echo function detailed in RFC792. It also measures round trip time and reports errors. Ping works by sending a packet to a provided address and waits for the reply. Ping (Packet InterNet Groper) is a computer network administration utility that helps one to check either a particular IP address or domain is accessible on the computer network or not. We use two standard programs, namely Ping and Traceroute, to diagnose such obstructions, network failures, or technical errors. But sometimes, due to some hurdles, like network congestion, the webserver is down, or some other technical error, there are the chances that the message will not reach the destination.

All packets are re-assembled to form the original message. Once all the packets of the original message reach the destination. Each packet is transmitted individually and may adopt a different route to reach its destination. In a computer network, the data is sent in small blocks called packets. They are short in number, and the maximum available to be ever assigned to devices are 4,294,967,296. The IPv4 was the first kind of IP created in networking. The IPv4 addresses are 32-bits long and use DNS A records to map the hostname to an IP address.

IPv4 (Internet Protocol Version 4) is the most widely used form of an IP address. Just put an IPv4 address to ping it online. Ping utility helps to check if the destination IP is assigned to some device and responding respectively. Online Ping IPv4 tool sends ICMP packets to ping a destination IP or domain to check either it's accessible on the IP network or not. About IP Pinger - Ping IPv4 Address Online.If it's not ethernet, you get the appropriate kind of MAC addressing for that medium 48-bit, 64-bit, none.As the IP packet goes from hop to hop, different routers are saying "I have this for you", so of course the frame would have different source and destination addresses.On ethernet the frame says "I have this for you", where "I" and "you" are defined by the source and destination ethernet addresses.To pass a packet in ethernet, it must have ethernet source and destination addresses in order to get to just the right node on the ethernet.If it's convenient, a given set of links might be replaced by ethernet.Then, exactly as you imagine, packets just have fixed IP source and destination address from host A to host B.Many point to point links have no link addressing: just send the packet in some kind of framing and the other end receives it.Suppose there's no ethernet, and all of the hosts and routers have a direct point-to-point links (with the same connectivity, ie A to R1).It's only rewording what others have already said, but the way I usually explain this is with a thought experiment: * Broadcast and multicast packets need more special handling, but that is outside the scope of this question.

On the other hand if the link is a serial point to point interface then there may be no MAC addresses involved at all and other protocols may have their own addressing scheme. If the connection is Ethernet then the IP packet will be encapsulated in an Ethernet frame with the router's interface as source MAC and a MAC address looked up using the next-hop IP address as destination MAC address.
