Windows 10: How to Set IP Address using netsh on PC
IP address definition
An IP address is a unique address that identifies a device on the internet or a local network. IP stands for "Internet Protocol," which is the set of rules governing the format of data sent via the internet or local network.
In essence, IP addresses are the identifier that allows information to be sent between devices on a network: they contain location information and make devices accessible for communication. The internet needs a way to differentiate between different computers, routers, and websites. IP addresses provide a way of doing so and form an essential part of how the internet works.
What is an IP
An IP address is a string of numbers separated by periods. IP addresses are expressed as a set of four numbers — an example address might be 192.168.0.1 Each number in the set can range from 0 to 255. So, the full IP addressing range goes from 0.0.0.0 to 255.255.255.255.
IP addresses are not random. They are mathematically produced and allocated by the Internet Assigned Numbers Authority (IANA), a division of the Internet Corporation for Assigned Names and Numbers (ICANN). ICANN is a non-profit organization that was established in the United States in 1998 to help maintain the security of the internet and allow it to be usable by all. Each time anyone registers a domain on the internet, they go through a domain name registrar, who pays a small fee to ICANN to register the domain.
How do IP addresses Work
If you want to understand why a particular device is not connecting in the way you would expect or you want to troubleshoot why your network may not be working, it helps understand how IP addresses work.
Internet Protocol works the same way as any other language, by communicating using set guidelines to pass information. All devices find, send, and exchange information with other connected devices using this protocol. By speaking the same language, any computer in any location can talk to one another.
The use of IP addresses typically happens behind the scenes. The process works like this:
-Your device indirectly connects to the internet by connecting at first to a network connected to the internet, which then grants your device access to the internet.
-When you are at home, that network will probably be your Internet Service Provider (ISP). At work, it will be your company network.
-Your IP address is assigned to your device by your ISP
-Your internet activity goes through the ISP, and they route it back to you, using your IP address. Since they are giving you access to the internet, it is their role to assign an IP address to your device.
-However, your IP address can change. For example, turning your modem or router on or off can change it. Or you can contact your ISP, and they can change it for you.
-When you are out and about – for example, traveling – and you take your device with you, your home IP address does not come with you. This is because you will be using another network (Wi-Fi at a hotel, airport, or coffee shop, etc.) to access the internet and will be using a different (and temporary) IP address, assigned to you by the ISP of the hotel, airport or coffee shop.
Netsh Command
Anyone who works with Windows network configurations will eventually come across the Network Shell (Netsh). The term refers to an interface between users and the operating system, which enables the administration and configuration of local and remote network settings.
The range of applications includes settings for the Windows firewall and LAN/WLAN management as well as IP and server configuration. Moreover, networked infrastructure can also be protected from external attack. Using the command line tool, it’s also possible to diagnose problems and carry out repairs in the network. A big advantage of Netsh is that network-related administration tasks can be performed quickly and conveniently, and can be automated with scripts
