Usually a gateway or proxy is responsible for hiding internal networks.
NAT (Network Address Translation) is used to change private IP address into public IP addresses.
A private IP is for internal networks, a public one is for a WAN or the Internet.
A public address is one that is seen on the Internet and can be routed. A private IP address is only visible within its organization network and any packets containing a destination address using a private address will not be routed outside the organization.
Public. Private IPs are: 192.168.x.x 10.x.x.x and there's one other range, but I can't remember it right now. 159.x.x.x is public.
She doesn't have a public email address only her private one.
Wikianswers does not divulge private information about celebrities. Public information will be published, and commonly a private address is not one of these things.
When running NAT the purpose of address overloading is to map a number of private IP addresses to one public IP address.
If you want to share a public IP address with several internal systems then you need to configure the use of NAT (network address translation). It is a gateway/proxy service that translates internal addresses to external addresses and would allow you to share the external public IP address with multiple internal addresses.
Public network is where the networked computers are not all trusted. Private network is where all computers are trusted. EG. Public network: cyber cafe. EG Private network: Your work or home network.
Your public or external ip address will change, but if you use a router and you have things setup to use a static ip address then your computers private or internal ip address will stay the same but your public or external ip address will still change. Public or External IP Addresses are assigned by your internet service provides. Private or Internal IP Addresses are determined by your router if you have one.
A computer on the Internet is identified by its IP address. In order to avoid address conflicts, IP addresses are publicly registered with the Network Information Centre (NIC). Computers on private TCP/IP LANs however do not need public addresses, since they do not need to be accessed by the public. For this reason, the NIC has reserved certain addresses that will never be registered publicly. These are known as private IP addresses, and are found in the following ranges: From 10.0.0.0 to 10.255.255.255 From 172.16.0.0 to 172.31.255.255 From 192.168.0.0 to 192.168.255.255
Private IP Addresse Because of NAT redirection a small company can rely solely on private IP addresse for its internal network and use only the s one public IP assigned to it by is ISP for Internet communication IEEE recommends that the following IP addresse be used for private networks 10.0.0.0 through 10.255.2 172.16.0.0 through 172.31.255.255 192.168.0.0 through 192.168.255.255
NAT or Network Address Translation actually comes in several flavors. Simply NAT and NAT PT (Port Translation) are available in both IPv4 and IPv6. NAT uses a router or Integrated Service Router to translate your private IP address to a public routable address. Most home DSL or cable modems provide NAT services. 192.168.0.0 through 192.168.255.255 are defined as private addresses or "Not routed over the Internet" addresses. There are other ranges such as 10. which won't be not routed over the public Internet What NAT does is translate your private addresses to a public address or list of possible public addresses. PT which is sometimes referred to as port overload will send request using the same public address by associating the private address with a specific port. Simply this means that even if only one public address is available many private requests can be serviced by assigning and then tracking a port assignment at the NAT point of service. So if two NAT/PT serviced hosts both request different HTTP page downloads on the same public address each is assigned a different TCP port. When the request return they are routed to each private address based on the port number. Cool how it works. This is not the same as proxies so don't get confused.
