Used for link-local addresses [5] between two hosts on a single link when no IP address is otherwise specified, such as would have normally been retrieved from a DHCP server 172.16.0.0/12 172.16.0.0–172.31.255.255
Ping operates by means of Internet Control Message Protocol (ICMP) packets. Pinging involves sending an ICMP echo request to the target host and waiting for an ICMP echo reply . The program reports errors, packet loss , and a statistical summary of the results, typically including the minimum, maximum, the mean round-trip times, and standard ...
In computing, a ping sweep is a method that can establish a range of IP addresses which map to live hosts. The classic tool used for ping sweeps is fping, [ 1 ] [ 2 ] [ 3 ] which traditionally was accompanied by gping to generate the list of hosts for large subnets, [ 4 ] although more recent versions of fping include that functionality.

Mobile broadband usage among individuals in Portugal increased to 82% in 2021, up from 72% in 2018, yet it slightly trails the EU average uptake of 87%. Despite this progress, Portugal's advancement in 5G deployment was notably absent in 2021, with 0% coverage, while other EU member countries were significantly ahead, achieving an average 5G coverage of 66% across populated areas.
The Internet Protocol (IP) is the network layer communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking , and essentially establishes the Internet .

A ping of death is a type of attack on a computer system that involves sending a malformed or otherwise malicious ping to a computer. [1] In this attack, a host sends hundreds of ping requests with a packet size that is large or illegal to another host to try to take it offline or to keep it preoccupied responding with ICMP Echo replies.
Computers can maintain lists of known addresses, rather than using an active protocol. In this model, each computer maintains a database of the mapping of Layer 3 addresses (e.g., IP addresses) to Layer 2 addresses (e.g., Ethernet MAC addresses). This data is maintained primarily by interpreting ARP packets from the local network link.
