This subchapter looks at arp, a UNIX (and Linux) command.
arp is used to display and modify the Internet-to-Ethernet address translation tables.
Use the -a option to display all of the current ARP entries. Useful in conjunction with ifconfig and route.

free music player coding example
Coding example: I am making heavily documented and explained open source code for a method to play music for free almost any song, no subscription fees, no download costs, no advertisements, all completely legal. This is done by building a front-end to YouTube (which checks the copyright permissions for you).
