What type of address is Is it private or public? Is it your default IP address? It could be a client’s IP address. This address could I be used as a static ip to my printer? This article has all the answers.

Rules for IP Addressing

IP addresses are used for identifying devices on the internet or any smaller network. From a networking standpoint, your device is effectively invisible without an address. Other devices having IP addresses will be unable to see your device, and your device will be unable to communicate with other devices if it does not have an assigned IP address.

The IP protocol (IPv4) is the definition of an IP address. You have two forms of an IP address – decimal and binary. The binary form represents what computers, servers, smartphones and routers (etc.) see. The binary form is what machines (computers, servers, smartphones and routers) see, while the decimal format is what we see. The decimal form is a modified version of the binary format.

An IP address is 32 bits in binary format (bits are ones and zeros). It’s basically a long string of 0s and 1s. This string can be divided into four octets. An octet refers to a group consisting of eight 1s and 0s.

Any octet can be converted into an actual number. This decimal form is what we recognize as an IP address. Eight 0s and 1s cannot be used to produce any number. You can only make numbers between 0 and 255. Because eight 1s equals 255, making 256 or a higher number is impossible. Eight zeros, on the other hand, convert to zero (thus an 8-bit value cannot be negative).

This information is crucial to determine the validity and invalid form of an IP address. The address is invalid if any of the four numbers within it is greater than255. The address can also be invalid if it contains more than 4 numbers (e.g. 5).

Example: can be used as a valid address (four numbers, each between 0 to 255). numbers rather than 4 are invalid addresses. The invalid form of IP address (because the last number exceeds 255) is also

Apart from IPv4, there is also the IPv6 protocol. This protocol increases the number of available addresses significantly, but it’s not in use, yet. In the future, the IPv6 protocol is expected to be implemented.

IPv4 protocol defines IP addresses. This gives us 4.3 billion unique IP addresses (232). That is the total number of unique 32-bit combinations. Isn’t that rather a lot? It appears to be, but it isn’t. Although it used to be a lot, technological advancements have allowed more gadgets to connect to the internet. When we inform you that every device linked to the internet need its own IP address, you can see that we have a problem: 10 billion devices and only 4.3 billion addresses.

IP addressing authorities found a simple, but elegant solution to this problem. They made three blocks of dedicated private addresses (18 million) and created a new classification. So, let’s talk about the many classes of IP addresses.

Types Of Addresses

The 4.3 billion addresses can be divided into classes according to their purpose and the network they are connected to. You can also distinguish between private and public addresses. You can also differentiate between static addresses and dynamic addresses. These addresses are all explained in detail.


There are five classes of IP addresses. The first three are used on networks (Class A – large networks, Class B – medium-sized networks, Class C – small networks). The Class D address is used to broadcast, and the Class E address is used for experimental and other purposes.

5 classes of IP addresses

Each IP address can be separated into two pieces, one for the network and the other for the client, regardless of the class.

Class A addresses can only be used in networks with many clients. The Class A IP address defines the network by 8 bits. (The first number defines it). 24 bits make up the part that defines the client within a Class-A IP address. This means you can have 127 large networks with more than 16.77 million clients.

Class B addresses can be used in smaller networks that have fewer clients than class A. The 16-bit part that defines the network within a Class A IP address is the first two numbers of an IP address. 16 bits are the part that defines a client in a class B IP address. A Class B network may have 216 clients (65 536)

Class C addresses are for small networks with no more than 254 clients. 24 bits are the part that defines the network using a Class C IP Address. The first three numbers of an IP address define the network. 8 bits are the part that defines the client within a Class C address.

This classification of IP addresses does not solve the problem of limited IP address availability, but it does introduce some structure and makes IP address assignment easier.

Private vs Public Addresses

Private addresses were introduced to solve the problem of too many IP addresses. According to the chart above, you have three blocks of private addresses: Class A addresses (10.x.x.x), Class B private addresses, and Class C private addresses (192.168.x.x). The number of private addresses relative to the available addresses is small (18 million VS 4.3 billion). Although it seems impossible for 18 million addresses to solve the problem, when you consider that there are more devices than IP addresses that can connect to the internet, you will soon learn the full story.

You can use any of these 18 million private addresses unlimited times on LANs (local-area networks), but not multiple times. The only rule is that you can’t use a single IP address twice on the same LAN. Other LANs, however, are different. You can have one device on each LAN around the world by using the address in the title ( As the name implies, LAN is a network that interconnects only a small number of devices. A LAN network, for example, is every home wi-fi network. School network, lab network, campus network, office network – these are all local area networks.

We can also use private addresses to address all devices on LAN networks. All devices on the same LAN network will be able to communicate with one another using these addresses. What happens when you want those devices to connect to the internet? You can’t connect millions of devices to the internet using the same private IP addresses.

That is why we do not access the internet through private addresses. How do we get to the internet? You click on the YouTube icon and the YouTube website will open. It’s quite amazing to see what happens in real life.

Routers allow us to connect to the internet from our devices (laptops, computers, and smartphones). Routers are an essential part of any LAN network. They are responsible for assigning IP addresses to each device on a LAN network. Additionally, they allow communication between devices on the same local network. They also allow all devices connected to a single LAN to connect to the internet.

Your router has two IP addresses: one is private and provided by the manufacturer (also known as default IP address), and the other is public and assigned by your internet provider to it (or rather, your complete wi-fi network). It communicates with all devices connected to the LAN via its private address. Your devices send requests to routers when they want to connect to the internet. The router then uses a public IP address for accessing the Internet and finding the information you require. It forwards the information to your device when it receives feedback from DNS servers.

Your router acts as a bridge between all devices that are connected to a LAN (your wi-fi), and the Internet.

This arrangement allows you to use the same public IP address for multiple devices connected to the LAN. To connect to the internet, all devices connected to your home wi-fi network use the same public IP address (your ISP assigns this address to your entire network).

Dynamic and static addresses

Each IP address can be either static or dynamic. Both public and private addresses are affected. The nature of the interaction between an address and a device is referred to as static or dynamic. Static addresses are those that are permanently assigned to a particular device or website. It’s called dynamic if the address is only leased and not permanently assigned.

Many of the devices on our home wireless network have changeable IP addresses. You can make any private address you assign to any device on your wireless network static. To assign a static IP to a device, navigate to your router’s settings and look for DHCP static lease or a similar option, then assign the device a static IP.

Public addresses can be either static or dynamic. Addresses that are assigned to our home networks (or to our routers, if necessary) are often dynamic. They can change but they don’t happen very often. Public addresses are also available for businesses, but they can only be used once. Businesses must pay more for static IP. Websites can have static addresses but they can share the same address with other websites.

Theoretically, router manufacturers have the ability to use any private IP address and assign it their routers.

Manufacturers often use subnet addresses to simplify things in practice. The most common choices are, and Both addresses are the starting addresses of their respective subnets (, Other options include which is the end address for the subnet or

We’re not aware of any router manufacturer that utilises as a default IP address, but we did find one access point produced by Luxul that does. Luxul’s model is XAP-1030.

This means that may not be your default IP address. This guide will help you find your default IP address.

As a default IP address, use

If you, by any chance, are using Luxul XAP-1030, then this address is your default IP address and you can use it to log into the access point’s settings. Enter it in your browser, and then press Enter. Use the default username/password (admin/admin) when asked for credentials.

Can serve as a Client IP address? is one of most popular default IP addresses and is part of the same subnet. The address from the title could easily be one in your DHCP pool. It can then be assigned to your smartphone, laptop, or computer. This address can also be used to identify clients. It’s actually much more often used as a client IP than a default IP address. as a Dynamic IP

Dynamic IP at

Your router will assign a static IP address by default to every device that connects via your wi-fi. As previously stated, a dynamic address is leased and can be returned to the DHCP pool when the device disconnects and the lease duration expires.

IP address:

By entering into your router and heading to LAN settings, you may permanently assign an IP address to any device. The static lease (or static assignment) option can be found in the DHCP settings, or there may be a special tab for DHCP static lease. There is a specific tab in this case. Simply open it and enter the MAC address of your device as well as the desired IP address. You may also be required to input the device’s name in some circumstances. If you don’t know the name of your device, look through the list of connected devices and then look for it.

Before assigning any address to your device check to see if it is already assigned. If the address is already assigned to another device, you will need to remove it first. If you don’t, you’ll have two devices with the same IP address on the same LAN. This is referred to as an IP conflict.
