is another IP address from the group of private addresses from Class C (all the 192.168.x.x addresses belong to this block). This address might look familiar to you and that’s because you’ve probably seen it before. It can sometimes be a default gateway for your router (but and 1.2 are much more common) but it is more often the address assigned to one of your devices (PCs, laptops, phones, etc.) within a home or some corporate network.

In this article we will be dealing with the basics of IP addressing – protocols, different types of IP addresses (public-private, static-dynamic) and we will try to tell you everything you need to know about the address from our title, whether it is used as a default gateway or just another IP address assigned to one of your devices. In the end, we will give you step-by-step guide on how to assign to one of your devices (how to make it static IP), point out some things you should think of before assigning static IP address to your device and give you some pieces of advice on how to avoid connection issues when assigning static IP address to your device.

Importance of IP addressing

IP address is the decisive precondition for online communication. Whether you want to access the internet or some local network, the device you are using needs an exclusive (or unique) IP address. Think of it as of your home address or your phone number. You can’t make any calls if you don’t have a unique phone number just like you can’t get any mail if you don’t have a home address. Having a unique IP address makes your device visible online and enables communication with other devices.

Basics of IP Addressing – Internet Protocols (IPv4 and IPv6), IP Classes, Public and Private IP addresses, Static and Dynamic Addresses

During the 1970s, a set of rules was established in order to define the default form for IP address and design the best possible way of assigning addresses to all devices on the network. This set of rules was named Internet Protocol, precisely IPv4 and it is still in use. According to IPv4, IP address is a 32-bit code consisting of 4 bytes (4 groups of 8 bits) and these bytes are separated by dots. If you look for your PC’s IP address, you won’t actually see this kind of notation made of 1s and 0s. You will see something called decimal notation, which is notation made of four numbers ranging from 0 to 255, with dots separating those four numbers (just like the address from the title – These two notations – binary and decimal, are in fact, the same thing. Each sequence of 8 1s and 0s can be decoded into a number ranging from 0 to 255, and decimal notation is there to simplify things and make IP addresses easier to read and write. In order for some device to read your address, that address has to be binary (that’s how computers work), but in order for us to understand them and work with them, it’s easier to have decimal notation. So, any IPv4 address is, in its core, binary – we just translate them into decimal notation for our convenience. This protocol invented in the 1970s offers maximum of 232 possible IP addresses (nearly 4.3billion) which is a lot but probably not enough for the future considering the number of people living on Earth (which is already much higher than 4.3 billion), the number of different devices produced every day, the size of the internet and the growing number of websites, etc.

For future purposes, a new protocol was designed and it was named IPv6. This protocol is similar to its predecessor – the only difference is that IP address is defined as a much longer code. Now, we have 128-bit notation made of 8 16-bit parts (called words) separated by a colon. So, we have 128 bits and not 32, 16-bit groups instead of 8-bit, and we have colons and not dots. This new protocol offers a much bigger number of IP addresses (340 undecillion) and that’s the most important thing and the purpose of this protocol (to offer a unique IP address for all the future devices). IPv6 didn’t come into force, yet. Slow and smooth transition from old one to this new protocol is going to last a few years or decades, there is no precise deadline.

Considering that IPv6 is still not in use, our further story is related to IPv4 Protocol.

In order to simplify the process of assigning, all the IP addresses are split into 5 classes. Each class has its purpose, and depending on the size of the network, different users and devices will get IP addresses from different classes. Classes A, B, and C are reserved for commercial purposes (Class A for multinational companies, Class B for large companies and ISPs, Class C for smaller companies) while D and E are reserved for multicast and different tests.

All these addresses from the first three classes (those reserved for different-sized companies and ISPs) we’ve mentioned are addresses that can be routed on the internet. That’s why we call them public addresses. What you don’t know is that there are special blocks of addresses within Classes A, B, and C, that can’t be accessed from the internet and they are called private (the most recognizable are A and C block – 10.x.x.x and 192.168.x.x). You can see that is one of the private IP addresses from the block C. These private addresses are assigned to private networks – home and corporate (intranet) networks. Block C addresses are more often used for home networks, and Block A is used for corporate networks, but there is no rule about that and you can find routers and computers on your home network with 10.x.x.x addresses and vice versa.

So, for now, we know that is Class C address and that it’s a private address.

Two more terms we have to mention are static and dynamic addresses. can be both (just like any address). The meaning of these terms is pretty obvious – if you assign a static IP address to your device, your device will have that identical IP address every time it goes online, and if IP addresses are assigned automatically (dynamically), your device might have other IP address every time. So, if your device supports DHCP (which is a protocol that regulates dynamic assignment of IP addresses), can be assigned to your device, but it doesn’t have to be. You can get any address from the pool depending on which address is available (so, it can easily be or any other). Most devices on home networks support DHCP and have IP addresses assigned automatically, but if you need static IP for some of your devices, you can set it up manually. Some devices must have static IP within some intranet or home network (like data servers on a corporate network) and for those devices, the process of assigning IP address is done manually and with caution (we will explain this process later). If you are using your home network to host a website, you will also need a static IP (because that website has to be accessible through the internet, and it won’t be if your IP changes every time you go online).

Static and dynamic IP addresses, as well as blocks of private addresses, are introduced in order to reduce consumption of IPv4 addresses. They actually preserved a huge amount of addresses and enabled a simple transition to IPv6. as A Default Gateway and as Your Computer’s IP Address

We’ve already said that can be default gateway address. The gateway address is an IP address used for accessing router’s configuration page. Any private address from block A, B, or C, can be assigned to a router, but some addresses are definitely more popular than others ( or is not an address you will often see as a default gateway but rather as an IP assigned to one of your devices, especially if your router’s gateway is (which is the most common one). So, if you are a Windows user and if you type in ‘’ipconfig /all’’ in command prompt, there is a chance that your device will have this exact IP address if your gateway is

How to Assign To Your Computer as A Static IP Address

If you need this address to be static (reserved) for some reason, you can assign it manually. We will give a step-by-step explanation for Windows users. Linux and Mac OS users will have to wait for our next article.

First of all, you should know that you will have to remember (or better write down) some IP addresses. When you use the command ‘’ipconfig /all’’ in Command Prompt, you will get all kinds of data. The things you have to write down are subnet mask (usually for any 192.168.x.x gateway), default gateway address, and DNS server addresses. When you are done, we can start the process of assigning static IP to your device.

Step 1 – Open Network and Sharing Center by right-clicking on the network icon in the bottom-right corner of your desktop and selecting this option

Step 2 – In Network and Sharing Center, select Change Adapter Settings

Step 3 – In this new window, you should right-click on your Wi-Fi network and select Properties

Step 4 – The window with Wireless Network Connection Properties will open. In Networking Tab, search for IPv4, left click once to select it and then left click on Properties

Step 5 – Ipv4 Properties window will open. You should stay in General Tab. In order to type in the new address ( or any other), you have to select ‘’Use the Following IP address’’ and type in the address you want to assign (that’s the first field). In subnet mask and default gateway fields, you should type in those addresses from the command prompt. Then, enter DNS server addresses (those from command prompt) and click OK.

Problems You May Encounter When Trying to Assign As A Static IP To Some Device

This process of assigning a static IP address to your device seems fairly simple, right? Well, usually it is simple, but sometimes, you may encounter some problems that could make networking impossible.

IP Conflicts

The biggest possible issue is an IP conflict. If two devices are in conflict that basically means that they have the same IP address. Since IP address has to be unique, having two devices with the same IP is not a normal situation. When you have two devices within the same network with the same IP address, none of these devices will be able to access the network (or the internet). That could easily happen with the address from our title. Why? Well, it’s simple. Let’s say you want to connect your device to a home network and assign static IP ( to this device. Imagine that you already have 2 or 3 devices present, and your new device is fourth. DHCP server (which is inside your router) assigns IP addresses to other devices. So, if your router’s gateway address is, and you have 253 different addresses at your disposal (from to, your DHCP server will assign addresses from this pool automatically. The first device will get, the next one will get, etc. So, it is possible that this address you want to assign to your new device is already taken. If you assign it to your new device, you will cause an IP conflict and two devices with the same IP won’t be able to connect to the internet. The way to avoid this conflict is to find the device with the exact IP address you want to assign to your new device and disconnect it. That way, this IP address will be free again (unassigned) and you will be able to reserve it for your new device. When you connect that old device again, some other IP address will be assigned to it by DHCP server and the conflict will be avoided.

Is A Good Choice for A Static IP Or Should You Choose Some Other Address?

This is closely related to the previous topic. If you have more than 2 or 3 devices, there is a great chance that this address is already taken. If you have even more devices and you don’t want to check which device obtained that specific IP you want to use, you should take some higher host number. For example, if there are 10 different devices connected to a network, is probably already taken, so if you want to be on a safe side, you can choose address like or You just have to be aware of the number of available addresses in DHCP server pool.
