An IP address that is most well known as an Internet Protocol address is a series of numbers that identifies a device in the internal or external network. In principle it is an identifier that is assigned to each device connected to a data network.
Private: This IP address is non-routable (routed) via the Internet and can be used only internally. And they are assigned by a DHCP server that is configured in a router or a server.
Public: It is an IP address that is assigned by the ISP that has contracted internet service. There are two types of classification for these public IP address:
The first is called: public IP dynamic, which is used in the residences. Which IP are also randomly assigned by the ISP contract. These IP addresses change every time resets the device, added a new device to the network or the network changes the configuration. Changes rarely have any impact on the services that are published to the internet.
The second is called: public IP static, which is assigned in a formal way determined by a contract by the ISP by the contract drawn up. The IP address is assigned fixed without being affected by any number of times that there is a restart of the DHCP server. These addresses are which are contracted for web sites, emails and services, TFTP, FTP, Games, VoIP, or others by IP Protocols. In the same way they can request the same organization when these service contracts are renewed. Users of these servers use it because it provides a very stable connections and a level of service (SLA). Rarely has a public static IP address is used for residential needs. If in case it is required you will need to pay an additional fee to have a public static IP to be assigned.
Each IP address contain a large number of data the ISP service providers using Internet services. Also you can do a trace of origin and destiny of the requests that are made online. The information contained may be as indicated below: disclose the information and the name of the ISP, location information, your browser, sites that are trying to access, and technology history of activity.
A request required by you to your ISP to reference matrix of selective public IP address with the Web site data captured versus the database of customer data that keeps the ISP, so we can deduce that the IP address is in some way a fingerprint which will usually coincide with their personal data record.
because there are several ways, which there are services like StrongVPN, EasyVPN, Tunnel Bear, OpenVPN, HideMyAss, Hotspot Shield Elite by AnchorFree, etc., which performs data encryption by hiding the actual public IP address so use one of the IP addresses assigned to their servers so those are displayed when someone is requesting.
It is made by the use of VPN (Virtual Private Network) technology which is a tool through the connection that I have a connection through a secure data tunnel. The secure tunnel masks with encrypted computer data so that your personal data are protected from being accessed by entities not authorized or intruders during your navigation on internet, so this provides a guarantee of safety and anonymity.
