Our Subnet Calculator simplifies IPv4 and IPv6 subnetting, allowing you to efficiently allocate IP addresses and manage your network. Try our comprehensive tool today for binary subnetting and network range calculations.
An IP address (short for Internet Protocol address) is a numerical label assigned to every device connected to a computer network that uses the Internet Protocol for communication. IP addresses are used to identify and locate devices on the internet or on private networks, and they enable devices to communicate with each other over the internet.
In computer networking, a subnet (short for subnetwork) is a portion of a network that shares a common network address. Subnets are used to divide larger networks into smaller, more manageable segments to improve network performance and security. By using subnets, network administrators can assign IP addresses more efficiently and control the flow of network traffic more effectively. Each subnet has its own unique network address, which is used to route traffic between subnets and to other networks.

Variable Length Subnet Masks (VLSM) allow network administrators to allocate IP addresses more efficiently by using different subnet masks for different subnets. In this FAQ, we explain what VLSM is, why it's important, and how to use our VLSM Calculator to make subnetting more efficient..
Binary Subnetting Made Easy with Our Binary Subnet Calculator
Binary subnetting is a technique for subnetting using binary numbers instead of decimal numbers. In this FAQ, we explain how binary subnetting works and how to use our Binary Subnet Calculator to perform binary subnetting calculations.
You can find your IP address by visiting a website that displays your public IP address, such as https://www.monodns.com/what-is-my-ip-address. This will show you your IP address, as well as other information such as your browser type and operating system.
There are several ways to obtain a static IP address. One way is to contact your Internet Service Provider (ISP) and request one. Some ISPs may charge an additional fee for a static IP address. Alternatively, you can use a Virtual Private Server (VPS), a Virtual Private Network (VPN), or a dedicated server, all of which can provide you with a static IP address. Once you have a static IP address, you can configure it on your device or network to ensure that it always uses the same IP address. This can be useful for certain applications or services that require a static IP address.
IPv4 uses 32-bit addresses, which means there are a total of 4,294,967,296 unique IPv4 addresses. However, not all of these addresses are available for public use, as some are reserved for special purposes such as private networks or multicast. Additionally, the growth of the internet and the increasing number of devices connected to it have led to a shortage of available IPv4 addresses, which has prompted the adoption of IPv6, a newer protocol that uses 128-bit addresses and allows for a much larger number of unique addresses.
There are three ranges of IPv4 addresses that are reserved for private networks:
10.0.0.0 to 10.255.255.255 (10/8 prefix)
172.16.0.0 to 172.31.255.255 (172.16/12 prefix)
192.168.0.0 to 192.168.255.255 (192.168/16 prefix)
Devices on private networks can use IP addresses within these ranges without conflicting with public IP addresses used on the internet. This allows for more efficient use of IP addresses on private networks and helps to conserve the limited supply of public IP addresses. It is important to note that devices on a private network can still access the internet through a network address translation (NAT) device that translates the private IP address to a public IP address.
IPv6 uses 128-bit addresses, which means there are a total of 340,282,366,920,938,463,463,374,607,431,768,211,456 unique IPv6 addresses. This is an enormous increase over the number of IPv4 addresses, which are limited to 4.3 billion. The larger number of IPv6 addresses is necessary to accommodate the growing number of devices connected to the internet and to support new technologies such as the Internet of Things (IoT) and 5G networks. While the adoption of IPv6 has been slow, it is expected to become more widespread in the coming years as the supply of available IPv4 addresses continues to dwindle..
