Internet has been around for quite a time now. While the super fast AT&T internet helps us travel around the entire universe without any boundaries, our IP address works as the passport we need to do so. Remember, when your IP address didn’t support a webpage? Yeah, well there’s a reason for that!

An IP address is the internet protocol address given to your computer, laptop and even mobile as a form of its identification. Every smart device be it a smart home appliance or one at work has an IP address. An IP address helps you to request, send as well as receive data alongside browsing various websites and webpages.

Types of IP address depending on their changes. A static IP address remains as its name suggests – static – and never changes. No amount of time or system reboot can force it to act otherwise. However, it can be tracked within the blink of an eye. Therefore, when it comes down to your privacy – you need to take precautionary measures for it. A dynamic IP address is a temporary address that can change time to time with or without a reboot. It offers more privacy in comparison to the static IP addresses. Thus, it can easily be said that it is more secure in comparison as well. Therefore, when it comes down to answering the very question that stands in this content piece’s title – it just cannot be a simple yes or no.

An IP address is not an attribute, characteristic or even a feature of any device. It is in fact owned by IANA, also known as the Internet Assigned Numbers Authority. The IANA further passes those addresses to the national agencies or business providers etc. This process occurs in a bulk form and not individually for each IP address one by one. Therein, your IP addresses are accessible to you because of IANA.

The moment you connect to the internet you are given an IP address by your internet service provider. The use a protocol called Domain Host Control Protocol (DCHP). Each ISP is leasing you an IP address, in short, and not actually selling you a permanent one. The lease period for your temporary IP doesn’t last long and is mostly reintroduced during the night hours. By night period here, we mean the moment you let go of your internet connection and put the device to rest.

On the off chance that you link through a router, then the present IP address belongs with your router for the time of the lease. Your PC will get a private address from the router, typically from the 192.168 address block. This address isn't extraordinary. A huge number of individuals will have that private IP address simultaneously. That is the reason it is never directed to the web. Your router utilizes a procedure called Network Address Translation (NAT) to change over your private address into something that the web will comprehend (general public address dispensed by your ISP in addition to a supposed port number). That private address regularly remains there for an extensive stretch, yet that is absolutely unessential for the web.

In short, if you are using your smart device outside your home and connect to a public Wi-Fi hotspot then you won’t have the same IP address but instead it’d be that allocated to your device by the hotspot owner’s ISP. There are various applications created to check your Wi-Fi, if you are interested or curious! So to put it in one line, yes, each device has its own IP address. However, it is not just one in number but 2! While one remains the same, is your public Wi-Fi the other changes every now and then, and is private.
