ipconfig in Mac OS X serves as a wrapper to the IPConfiguration agent, and can be used to control the Bootstrap Protocol and DHCP client from the command-line interface. [8] For example, you can release and renew an IP address if it happened to be assigned incorrectly by the DHCP server during the automated assignment process. [9]
To conduct a denial-of-service attack, an attacker may send ping requests as fast as possible, possibly overwhelming the victim with ICMP echo requests. This technique is called a ping flood. [12] Ping requests to multiple addresses, ping sweeps, may be used to obtain a list of all hosts on a network.

All nodes of the network receive the message, but only B replies since it has the requested IP address. B responds with an ARP response message containing its MAC addresses which A receives. A sends the data packet on the link addressed with B ' s MAC address. Typically, network nodes maintain a lookup cache that
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.

The utility is similar to ping which operates at a higher network layer – probing the network at the Internet Layer via the Internet Control Message Protocol (ICMP). Two popular variants exist. One is part of Linux iputils suite, [ 2 ] and cannot resolve MAC addresses to IP addresses.
Most email software and applications have an account settings menu where you'll need to update the IMAP or POP3 settings. When entering your account info, make sure you use your full email address, including @verizon.net, and that the SSL encryption is enabled for incoming and outgoing mail.
