public ip-addresses are used in the Internet (they are registered addresses). private ip-addresses are used in local networks. imagine you have a computer in your local network that has a public ip-address and your PC has simultaneously an Internet connection: if you try to ping this pc you wouldn't be able to tell which computer is replying, the local one or the webserver.
•If the hosts on a network using private IP addresses need to access the Internet, a problem arises because the private IP addresses are not allowed on the Internet. •The solution is to use NAT (Network Address Translation), which uses a single public IP address to access the Internet on behalf of all hosts on the network using other IP addresses.
They are normally the IP addresses which your computer uses to talk to your internet router/modem. They are not the same as the IP address that your router is known by on the broadband link.
Private IP addresses are designated for use within private networks and are not routable on the public internet. The ranges defined by the Internet Engineering Task Force (IETF) for private IP addresses are: 10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255, and 192.168.0.0 to 192.168.255.255. These addresses allow devices within a local network to communicate with each other while maintaining security and conserving public IP address space.
Yes. That's the whole idea of private IP addresses. With NAT, the outside world never "sees" your private IP addresses.Yes. That's the whole idea of private IP addresses.

NAT (Network Address Translation) A service that translates a private IP address to a public IP address in packets destined for the internet, then translates the public IP address in the reply to the private address.
They are private addresses. I think Class A
the IP address is assigned to your computer by your DHCP server you can only have 1 true ip address, although you can have ghost ip address and private ip addresses Private Addresses are not routable through the internet Ghosts IP addresses are normally used to cover something up, usually something illegal ;)

Public IP addresses
The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets (local networks): 10.0.0.0 - 10.255.255.255172.16.0.0 - 172.31.255.255192.168.0.0 - 192.168.255.255Also, IP addresses in the range of 169.254.0.0 -169.254.255.255 are reserved for Automatic Private IP Addressing. These IP's should not be used on the Internet. I usually use 192.168.0.1, 192.168.0.2, etc. and a subnet mask of 255.255.255.0 when assigning static IP addresses to computers on a small Local Area Networks (LANs). If a DHCP server is also on the LAN it's scope (range of IP addresses that it can assign to computers on the LAN set to obtain their IP addresses automatically) should be adjusted so it does not interfere with locally assigned static IP addresses.
