There are 101 ways to monitor your network but few are as integral to the longevity of your network as ping monitoring tools. The overall breakdown of statistical data is fairly sparse however, marking responsive hosts as OK, with a basic date, time and ping shown next to it. More than sufficient in many cases, but a rather basic approach when compared to the other options available.
Essentially, a Twinge flood is the same as a Ping flood and the solutions to protect a network from it are the same as for the main category of DDoS attack via ICMP: turn off ICMP, install a web application firewall or a stateful firewall, or install an intrusion detection system.
A DNS resolution function shows the hostname for a requested IP address if it can find it. The absence of a hostname for a record should raise alarms if that IP address was contactable because either your DNS records are out of date or you have an intruder on the network.
A ping involves a packet of data being sent to a specific IP address (known as an echo request), if the device is active and healthy it will respond (known as an echo reply) and likely provide additional information that might help diagnose any network issues.
If that gets through, you shouldn't have any problems with your connections to the destination host that you sent the test packet to. Bookmarks If the transmission provokes an ICMP error, then you would just try the test repeatedly, reducing the packet length each time.
Knowing that critical systems and services are working is a fundamental aspect of the network administrator's job, and Ping Monitoring is the most powerful tool for doing so. The sheer simplicity of the command is rather profound, especially considering the amount of information can be garnered from it.
The response to an echo request is immediate and so if the program that sends the request takes a timestamp the moment that the echo request is sent, and another the moment the response arrives, the system can calculate how long a packet takes to get to the target and back.
