What is a public IP?

Internet Protocol or IP addresses abbreviated There are generally two types of Private and Public.If you have ever wondered to know what is the difference between IP address, public and private, then you are at right place. In this post I will try to explain the difference between public ip and private IP address in layman's terms so that it becomes simple and easy to understand.What is a Public IP?A public IP address assigned to each computer connected to the Internet where each IP is unique. It will not be able to have two computers with the same public IP address in the entire Internet. Addressing scheme allows computers to "find each other" and do pertukaraninformasi. Users do not have control over IP address (public) that is assigned to a computer. Public IP address assigned to your computer by your Internet Service Provider directly after the computer connected to the Internet gateway.A public IP address can be either static or dynamic. A static public IP address can not be changed and is used primarily for hosting webpages or services on the Internet. On the other hand a dynamic public IP address chosen from a pool which is available at the address and each change happens one time to connect to the Internet. Most Internet users will only have a dynamic IP assigned to each computer. When there disconnetted or network disconnected / off when plugging it back it will automatically get a new IP.Buddy can check that you are using public ip in www.whatismyip.comWhat is a private ip?An IP address is considered private if the IP number falls into one IP address range to a private network such as a Local Area Network (LAN). Internet Assigned Numbers Authority (IANA) has mereservd following three blocks of IP address space for private networks (local networks):10.0.0.0 - 10.255.255.255 (Total Addresses: 16,777,216)172.16.0.0 - 172.31.255.255 (Total Addresses: 1,048,576)192.168.0.0 - 192.168.255.255 (Total Addresses: 65,536)IP addresses Private / Personal computers are used for numbering the private network including home, school and business LANs in airports and hotels that allows computers on a network to communicate with each other. Say for example, if a network X consists of 10 computers each of which can be given an IP starting from 192.168.1.1 to 192.168.1.10. Unlike the public IP, private network administrator is free to assign the IP address of their choice (provided the IP number on a private IP address range as mentioned above).Devices with private IP addresses can not connect directly to the Internet. Likewise, computers outside the local network can not connect directly to a device with a private IP. It is possible to connect two private networks with the help of a router or a similar device that supports Network Address Translation.If the private network is connected to the Internet (through an Internet connection via ISP) then each computer will have a private IP and public IP. Private IP is used for communication in the network where the public IP is used for communication over the Internet. Most internet users with a DSL / ADSL will have a public IP Ip like.You can know your private IP by typing ipconfig command in command prompt. Number that you see against "IPV4 Address:" is your private IP which in most cases will be 192.168.1.1 or 192.168.1.2. Unlike the public IP, private IP addresses are always static and natural.Unlike what most people think, is not a private IP which is impossible to track (such as private phone numbers) or are reserved for stealth Internet usage. In reality there is no public IP address that is not possible to track down because the protocol itself is designed for the area of ​​transparency.
