What is difference between public ip and isdn
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.
Private IP Address
A private IP is for internal networks, a public one is for a WAN or the Internet.
A public IP address is assigned to you by your internet Service Provider while your private IP is assigned to you by your internal router. You can loacte your public IP address on LocatedIP.com
Public Ip is the IP which is visible in WAN meams which goes out as a representative of our computer but private ips are the ips which we use within a company or organisation. They can be used in any company but public ips are unique. In short Public Ip is for outside organisation and private ip is for inside organisation.
that is for range only for the know private ip is -10.0.0.0 - 255.0.0.0 172.0.0.0 - 255.0.0.0 192.0.0.0 - 255.0.0.0 public ip is 125.0.0.0 -255.0.0.0 69.0.0.0 - 255.0.0.0 that series of the ip address is privat and public ip address
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.
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
difference between ip address and class
Usually a gateway or proxy is responsible for hiding internal networks.
You have to install a router with a DHCP server option on. In that way the public address will be assign to the router and your PC will get a private ip address from the DHCP server.
