200-301: Cisco Certified Network AssociateDemo

Private IPv4 addresses are designed for internal network use and are not publicly routable, so they can be assigned to devices that do not have Internet connectivity. They also avoid the scarcity and typical billing model associated with public IPv4 addresses, making them less costly than public addresses in many environments. They do not remove the need for NAT for Internet access, are not routed like public addresses on the Internet, and do not by themselves prevent duplicate address conflicts.
