What is a purpose of an ip address?

One of the most basic concepts of data networking is how devices connect and communicate within an IPv4 network. To understand this, we must look at the devices' unique IP addresses as well as the associated subnet mask and default gateway. With these three pieces of information, we know how a device communicates with others locally as well as across an entire network. In this article, I'll explain each aspect of a device's IP address configuration and how they work together in order to communicate with other devices on a network. IP addresses Easily the most widely understood component of the TCP/IP configuration is the IP address. Every device connected to a network must have an unique IP address to differentiate it from the others. An IP address is similar to the unique telephone number on your home phone or mobile device. The difference is that it consists of four segments called octets that are separated by a period. The numbers within each octet range between 0 and 255. Here's an example of a typical IPv4 address: 192.168.40.39 No other device on your network -- unless you are NEXT page: Subnet masks (Image: Rob Bouwman/Shutterstock with modification)

They are functionally identical -- all-hosts subnet broadcast. In the early days, long long ago, the all-zero's address ("Network") was used for broadcast traffic. That was later changed to the all-one's address ("Broadcast"), and that's what we use today. [NOTE] This is not the same thing as "subnet-zero" (or the all-one subnet) which is the the top and bottom subnets from a larger mask. eg. 192.168.1.0/24 broken into /28's: subnet-zero is 192.168.1.0/28 and all-ones subnet is 192.168.1.240/28 "Network Address" and "Broadcast Address" are the first and last address of a subnet. Could you provide any reference to this? I personally don't recall this at any point in my experience (which granted is limited) but am always looking to expand on what I know. I finally had time to research what I remembered to answer the question and didn't come across anything like this mentioned. Looking back at this because of another question, it looks like I still didn't clarify my question in the first comment. I was asking if you could provide a reference to the use of the network address for broadcast traffic. I have never come across this personally and would be interested in finding such a reference. The use of "0" in a IP addresss was defined in Special Addresses: In certain contexts, it is useful to have fixed addresses with functional significance rather than as identifiers of specific hosts. When such usage is called for, the address zero is to be interpreted as meaning "this", as i...

What Is an IP Address? If you use a computer, then you have an Internet Protocol (IP) address. You may not have thought twice about it and you will not be alone in this. Millions of computer use globally pay little mind to their IP addresses, also known as internet addresses. Internet Protocol is the set of rules that dictate the format of data that is shared over the internet. So, what is an IP address? Your IP address, simply put, is what allows you to access the internet. Think of it as your passport to the WWW. Essentially, it is your network address for your computer that directs the internet where to send your emails and data. Many computer users assign IP names that are easy to remember instead of the tangle of numbers the internet provides. For instance, you could give yours your name or a moniker you will easily recognize and remember. However, when the internet connects to your router, the technology will identify it by the unique IP address.The typicalIP address formatis a 32-bit number that identifies the network interface on your machine uniquely. The address is written in decimal digits with the format appearing as four 8-but fields separated by decimals. Basics of IP Addresses The internet address facilitates the communication of connected computers or smart devices over the internet. Through your IP address, the location of your device can be identified and differentiated from a host of other devices. As stated earlier, this address allows the internet to f...

A shared printer is another example of when to use a static IP address. If you have a printer that everyone in your house or office needs to share, give it an IP address that won't change no matter what. That way, when every computer is set up to connect to that printer, those connections remain indefinitely because the address never changes. • Do not choose any addresses that end with .0 or .255. These addresses are usually reserved for use by • Do not choose the addresses at the beginning of a private range. Addresseslike • Don't choose an IP address that falls outside the range of your local network. For example, to support all addresses in the 10.x.x.x private range, the

IP conflict A subnet cannot have a duplicate IP address. This means that if your laptop has an IP address of 10.1.10.1, no other devices on your network can have that IP address as it causes an IP conflict. If two devices have the same IP address, the network will confuse the devices, and to resolve the conflict, one will be kicked off the network.

IP addresses and subnet masks stand at the core of computer networking. They are not concepts that are easy to understand in their entirety, especially if you do not have a technical background. However, with a bit of help, anybody can understand the basics of IP addresses and subnet masks, what they do, and why they are useful.
