An IP address (short for Internet Protocol Address) is a network address that can only be assigned once for each device in a network. This is necessary so that data packets can be correctly addressed and delivered. An IP address is the unique identifier of a computer in order to define its location on the Internet. It shows which provider is being used. The 32-bit IP address (also called IPv4) consists of four blocks of numbers from 0 to 255. An example of an IP address consists of two parts. The front part, the network address, and the rear part, the host address. The network address is especially important for IP routing.
The host address is important for the router in whose network the host is located. With the help of the IP address, devices or hosts can be clearly assigned and reached in a network. Explanation of an IP addressMeanwhile, a changeover to 128-bit (IPv6) was necessary because the address space in the 32-bit procedure was no longer sufficient in order to be able to clearly assign all devices connected to the Internet. The expansion to IPv6 now enables significantly more devices to connect to the Internet. Instead of four billion numerical codes under IPv4, the new standard provides 340 sextillion addresses - that is, almost an infinite number. Types There are basically two different types of IP addresses. The static IP address and the dynamic IP address. One speaks of a static IP if it is permanently assigned. If a computer is assigned changing IP addresses while it is connected to the Internet, it is called a dynamic IP address.
Dynamic IP addresses can be found, for example, with private DSL connections from providers such as Vodafone, O², T-Online, Alice, or 1und1. When a customer dials into the Internet, they are assigned an unused IP address and deleted after selecting them. Static IP addresses, on the other hand, are mostly used by companies to better control access to an IP address within the company network, for example, can.IPv4 The IP address is available here with a bit code of 32 digits or four bytes. It can be displayed either as a hexadecimal or decimal number combination. The decimal notation is usually used for IPv4 addresses. For this purpose, the 32 bits of the IPv4 address are divided into 8 bits each and separated by dots. Example of an IPv4 addressIPv6 In contrast to IPv4, IPv6 uses 128-bit addresses.
The address is noted in hexadecimal in 16-bit groups. The last 64 bits are here for the host address. A valid IPv6 address would be, for example, 1234: 5678: 90BC: DEFG: 0000: 0000: 0000: 2345 The IP range describes an address range within the host part of the IP address. Various other devices can be connected within this range within a local network or with the web. All IP addresses in a range follow one another directly. The size of the range is determined by the subnet mask. The start of the IP range is limited by the actual network address. The end of the IP range is the broadcast address, which can be used for all devices connected to the same network. Example for IP range The IP address is 192.168.10.1 With a standard subnet mask, additional IP addresses within the range up to 192.168.10.254 must be assigned. The larger the IP range, the more devices can be used within a network.
What is my IP address?
There are several ways to find out your own IP address: In Windows, the local IP address in your own network can be found using the input console via the command ipconfig. On Mac computers, the local IP address can be found in the Network area in the system settings. Various tools are available on the Internet to determine the public IP address, such as wieistmeineip.de. How is the IP address located?
The IP address can be used to determine where the respective Internet user is. Different IP address ranges are distributed to Internet providers, large companies, and authorities. Deutsche Telekom customers could, for example, be assigned an IP address that begins with 79, 95, or 234. The precision of the location increases or decreases depending on the distance from the respective Internet dial-in node. In urban regions, the distance to the next node is usually relatively short. In rural areas, however, the distance is usually a few kilometers and the determination is less precise. Anonymity The IP address plays an important role when it comes to data protection and anonymity on the Internet. If you want to surf the web anonymously, have the option to use an anonymizer, which guarantees anonymous use on the Internet. Programs such as Tor or JAP are able to cover up traces on the web, but the speed of surfing suffers.
Due to the current legislation, Internet providers are obliged to delete the entire data stream after the session has ended. IP addresses assigned to customers must be deleted after seven days at the latest. According to the ECJ, IP addresses are considered personal data and therefore fall under the GDPR. The IP address of users may therefore only be stored in the storage is essential for the use of the website and the functionality of the website depends on it. In order to save IP addresses, the website operator must also have a legitimate interest. Significance for SEO The IP address plays an important role in link building and in recognizing unnatural link networks. For example, if a website receives links from other websites that are in the same IP class and use the same IP address space, this can be an indication of an unnatural link. Accordingly, webmasters must expect sanctions from Google. If, on the other hand, the backlinks of a website come from different C-Class networks, this can indicate natural link growth. In order to check the quality of incoming backlinks, SEOs should therefore also check the IP addresses of the linking websites.
