[citation needed] The lower one's ping is, the lower the latency is and the less lag the player will experience. High ping and low ping are commonly used terms in online gaming, where high ping refers to a ping that causes a severe amount of lag; while any level of ping may cause lag, severe lag is usually indicated by a ping of over 100 ms.

Tools such as ping, traceroute, MTR and PathPing use this protocol to provide a visual representation of the path packets are taking, and to measure packet loss at each hop. [ b ] Many routers have status pages or logs, where the owner can find the number or percentage of packets dropped over a particular period.
Unlike previous attacks using the ICMP protocol--Smurf attack, ping flood, ping of death--BlackNurse does not flood the destination with traffic. Instead, the researchers realized that the "Destination Port Unreachable" packet causes high CPU usage in the firewall that processes it. [ 3 ]
The client sets the segment's sequence number to a random value A. SYN-ACK: In response, the server replies with a SYN-ACK. The acknowledgment number is set to one more than the received sequence number i.e. A+1, and the sequence number that the server chooses for the packet is another random number, B.
A ping flood is a simple denial-of-service attack where the attacker overwhelms the victim with ICMP "echo request" packets. [1] This is most effective by using the flood option of ping which sends ICMP packets as fast as possible without waiting for replies.
The original DARPA Internet Protocol's RFC describes [1]: §1.4 TTL as: . The Time to Live is an indication of an upper bound on the lifetime of an internet datagram.It is set by the sender of the datagram and reduced at the points along the route where it is processed.
Essentially, a pingback is an XML-RPC request (not to be confused with an ICMP ping) sent from Site A to Site B, when an author of the blog at Site A writes a post that links to Site B. The request includes the URI of the linking page. When Site B receives the notification signal, it automatically goes back to Site A checking for the existence ...
