IP 計算器

IPTP Networks’ IP Calculator supports both IPv4 and IPv6.

Here are the easy and simple steps to use IPTP Network’s IP calculator tool.

IPV4 SUBNET CALCULATOR

A step-by-step guide to use IPTP Networks’ IPv4 Subnet Calculator.

To use IPv4 Subnet Calculator:

Choose the preferred Network class, which is determined by its first bits, by clicking either three options:

1. Class A (8 bits), B (16 bits) and C (24 bits).
2. Select the target Subnet from the dropbox according to the Network class you chose.
3. Enter the IP address. An example IP address is already in place and can be used immediately.

Hit the Calculate button to view the result list of all the network and IP address values.

The necessary data IPv4 Subnet Calculator needs to calculate:

IP address: IPv4 address uses a 32-bit address and can support 232 IP addresses. IPv4 has 4 groups of numbers – called octets. Each octet ranges between 0 and 255 and is separated by dots (.).

Network class: Network is divided into Class A, Class B and Class C. Class A network uses the first 8 bits of the IP address as its “network part.”, while Class B uses the first 16 bits and Class C uses the first 24 bits.

Subnet: Subnet includes two parts: The subnet mask, followed by the CIDR notation.

IPV6 SUBNET CALCULATOR

A step-by-step guide to use IPTP Networks’ IPv6 Subnet Calculator.

To use IPv4 Subnet Calculator:

1. 1. Select the target Prefix Length in the dropbox. Choose from the range of /1 to /128.
2. 2. Enter the IP address. An example IPv6 address is ready to use.
3. 3. Once you are done, you can click the Calculate button.

The IPv6 Subnet Calculator only requires 2 properties:

• Prefix Length: IPv6 prefix-length is the same as the IPv4 subnet mask. It is in four octets written as an integer between 1 through 128.

• IP Address: IPv6 is written in hexadecimal format, with colons (:) between 8 groups of 16 bits, for a total of (8 x 16 = 128) bits. The IPv6 address is represented as x:x:x:x:x:x:x:x, ranges from 0000:0000:0000:0000:0000:0000:0000:0000 to ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff.

A subnet, or a subnetwork, is a subdivision of an IP network. Subnets are formed when a network is divided into two or more linked networks.

Subnetting is the act of creating subnets. Subnetting is used to minimize traffic and improve network speeds. Network speeds will be boosted when separating a big network into numerous smaller networks, thus lowering the number of paths required to locate a single device.

Devices also have a subnet mask, which defines whatever IP address part belongs to the network or the device. To connect to other networks, a gateway is needed. When a device communicates with another device on a different network, the information is routed to the gateway and then to its final destination.

The Internet Protocol (IP) is a data-transfer protocol that allows devices to communicate over the Internet. IPv4 is a 32-bit address, whereas IPv6 is 128-bit. Each device has its IP address, which is drawn from the IPv4 or IPv6 pool, and consists of two parts: the host (the client) and the network (the server).

The network part identifies a specific network and the host part identifies the node (a device). CIDR (Classless Inter-Domain Routing) assigns networks and devices unique IDs. The network address is the same for all hosts in a subnetwork, whereas the host address is unique.

A block of IP addresses is represented by CIDR (Classless Inter-Domain Routing). A CIDR IP address is similar to a regular IP address, except that it ends with a slash and a number, called the IP network prefix.

Subnetwork has three most commonly used classes, which are Class A, B, and C. Each class relates to a specific range of IP addresses and has a default subnet mask.
