IP address

An IP address, short for Internet Protocol address, which helps you to identify your router network hardware connected to a network. Having an IP address used to communicate with other devices like wireless routers, wifi routers over an IP-based network like the internet.

What is the Use of IP Address?

IP address gives an identity to your network setup device with your internet connection. It is similar to a home or business address supplying a specific physical location with an identifiable address, devices on network settings are differentiated from one another through IP addresses.

If you want to send a package to your friend who is staying in another country, to send the package you need their exact destination. The same process is used while sending data over the internet connection. However, instead of using a physical mailing address, your computer uses DNS servers to look up a hostname to find its IP address.

For example, You need to enter a website URL https://192.168.1.1 to configure Linksys router, your request to load that page is sent to DNS servers that look up the hostname to find its corresponding IP address. Without the IP address, your computer internet settings would have no clue what it is that

Different Types of IP Addresses:

If you don't have any idea about the IP address, you don't know that specific types of IP addresses. Actually, all Ip addresses are made up of numbers or letters, but all IP addresses are used for different usage.

There are private IP addresses, public IP addresses, static IP addresses, and dynamic IP addresses. That's quite a variety!

To add to the complexity, each type of IP address can be an IPv4 address or an IPv6 address again, more on these at the bottom of this page.

Private IP Address: These are used "inside" a network, like the one you probably run at home, used by things like tablets, Wi-Fi cameras, wireless printers, desktops, etc. These types of IP addresses are used to provide a way for your devices to communicate with your router and all the other devices on your private network. You can set this Private IP addresses manually or assigned automatically by your router factory settings.
Public IP Address: This network setup can be used on the outside of your network and are assigned by your ISP. It's the main address that your home or business network uses to communicate with the rest of the networked devices like Linksys router login, Linksys router IP around the world. It provides a way for the devices in your home, for example, to reach your ISP, and therefore the outside world, allowing the host address to do things like access website login credentials and communicate directly with other computers and servers around the world.
Both private IP addresses and public IP addresses are either dynamic or static, which means that, respectively, they either change or they don't.

An IP address that is assigned by a DHCP server is a dynamic IP address. If a device doesn't have DHCP enabled or doesn't support DHCP, then the IP address must be assigned manually, in which case it's called a static IP address.

What Is My IP Address?
Different devices and operating systems require unique steps to find router IP address. There are also different steps to take if you're looking for the public IP address provided to you by your ISP, or if you need to see the private IP address that your router assigned to your router settings. You can also visit 192.168.l.l in your address bar to change your router password.
There are lots of ways to find your router's public IP address, but sites like IP Chicken, WhatsMyIP.org, WhatIsMyIPAddress.com, or icanhazip.com make this super easy. These wireless routers work on any network-connected device that supports a web browser, like your smartphone, iPod, laptop, desktop, tablet, etc.

Another good way to find your external IP address in Windows is by using the following command in the Command Prompt:
In Windows, you can find your device's local IP address via the Command Prompt, using the ipconfig command.

See how do I find my default gateway IP address? if you need to find the IP address of your router gateway, or whatever device that your network setup uses to access the public internet.

Linux: Linux users can launch a terminal window and enter the command hostname -I (that's a capital "i"), ifconfig, or ip addr show.
MacOS: For macOS, use the command ifconfig to find your local IP address.
iOS: iPhone, iPad, and iPod touch devices show their private IP address through the Settings app in the Wi-Fi menu. To see it, just tap the small "i" button next to the network it's connected to.
Android: You can see the local IP address of an Android device through network Settings > Network & internet > Wi-Fi, or depending on your Android version, Settings > Wi-Fi or Settings > Wireless Controls > Wi-Fi settings. Just tap the factory network you're on to see a new window that shows network information that includes the private IP address. You might have to expand an Advanced area of the network's details page to see the private IP address.
IP Versions (IPv4 vs IPv6)
There are two versions of IP: internet protocol version 4 (IPv4) and Internet protocol version 6 (IPv6). If you've heard of these terms, you probably know that the former is the older version, while IPv6 is the upgraded IP version.

What Is IPv4 and IPv6?
One reason IPv6 is replacing IPv4 is that it can provide a much larger number of IP addresses than IPv4 allows. With all the devices you may have constantly connected to the internet, it's important that there's a unique address available for each one of them.

IPv4: The way IPv4 addresses are constructed means it's able to provide over 4 billion unique IP addresses (232). While this is a very large number of addresses, it's not enough for the modern world with all the different devices people are using on the internet.
IPv6: IPv6 supports a whopping 340 trillion, trillion, trillion addresses (2128). That's 340 with 12 zeros! This means every person on earth could connect billions of devices to the internet. True, this is a bit of an overkill, but you can see how effectively IPv6 solves this problem.
Visualizing this helps understand just how many more IP addresses the IPv6 addressing scheme allows over IPv4. Pretend a postage stamp could provide enough space to hold each and every IPv4 address. IPv6, then, to scale, would need the entire solar system to contain all of its router IP address.
In addition to the greater supply of IP addresses over IPv4, IPv6 has the following added benefits:

No more IP address collisions caused by private addresses.
Auto-configuration
No reason for Network Address Translation (NAT)
More efficient routing
Easier administration
Built-in privacy, and more.
IPv4 displays addresses as a 32-bit numerical number written in decimal format, like 10.0.0.1 or 192.168.l.l.
