Here you just have to type: ipconfig and press enter. Open a command prompt - Start -> Run -> and typing: cmd. Here you can simply find the IP directly on your PC. the local network (for example, a household or a company). Local IP address - the IP address which is operated in LAN, i.e. Hostname - This is in fact a text transcript of an IP address which also serves for identification in the network. My IP address (IPv4 or IPv6) - a unique address that identifies your computer on the Internet. Generally, you will find following information:
To find all available information about an IP address and about your connection in general it is good to visit a specialized website that can do it. Differences between public and non-public IP rest mainly in security, but today when various protective elements are both commonplace and necessity this aspect is disappearing. A dynamic address can be changed every time you connect to the Internet. Broadly speaking, a static IP address is permanently assigned by the operator and is constant.
A common user is basically not able to tell the difference between the two. You cannot connect to the Internet without an IP address. It is important to say that IP addresses are divided into static and dynamic. We list only the most practical and easiest options. There are several ways to find out what the IP address is. This is the question that most of Internet users will encounter at least once in their lifetime. Despite the use of 128 bit encryption and thus quadrupling the length of the address the datagram header is only twice as long compared to IPv4. Technical improvements are apparent in the IPv6 datagram. For this reason various converters are used to convert one protocol to another. IPv6 is not backwards compatible with IPv4 but in practice it is not possible for IPv6 users to be cut off from most of the Internet which still uses and will use the old solution. However, the situation was different for internet providers who had to take coming of the new standard into account. The transition from IPv4 to IPv6 was not noticed by users. IPv6 was a crucial improvement necessary for the further development of the Internet. IPv6 has a simple structure and its new routing capabilities increase overall performance which was inadequate in IPv4. And the space would still not be exhausted. In practice, this allows assignment of billions of IP addresses to each of the people living on the planet. The main and most fundamental difference is the transition to 128-bit encryption. The successor of IPv4, called IPv6, is a protocol that should solve the problem of a lack of address space. IPv4 did run out, it happened in February 2011. Thus providers did not have to assign the entire class, but only a part of the network that was more appropriate. The mask is the number after the slash and it represents a certain part of the network. Example of an IP address with mask is 192.168.47.0/29. One solution was the introduction of masks which split into different subnets. The number of devices in the network was determined by classes that have a major disadvantage - it is difficult to regulate their scope. Telling fact may be that the original design of IP protocol did not allow for the emergence of subnets. Everything has been put forward by the exponential development of the Internet but also by wasting IP addresses. In the 1990s there have been some concerns about the fact that there will not be enough IPv4 addresses and that they will run out very soon. Decimal system is used only because of clearer arrangement the network devices convert IPv4 to a binary system in which they work. The architecture of IPv4 is 32 bits - meaning that it consists of 4 octets separated by periods. So the data are not sent as a whole but are divided in smaller parts. If we want to deal with technical details of IPv4 we have to start by saying that it is used in networks where there is a packet switching. This solution was first described in 1981 and became the first truly widespread IP protocol.
Without IP addresses the routers in the network would not know where to send the datagram. Each device that is connected to the global Internet network must be assigned its own IP address that is unique and works on the basis of a numerical code. Internet Protocol version 4, IPv4, is basically a synonym for modern Internet and it is also its main building block.
