- 3 is a reference diagram for explaining an IP address and a subnet mask.
- IP address is a unique number that identifies a device connected to the Internet and consists of 12 decimal digits, for example (218.237.65.14). Each decimal number represents 8 binary digits, so an IP address consists of 32 bits. Expressing 218.237.65.1 in binary form is as follows.
- IP addresses are divided into network addresses and host addresses.
- a network address is used to identify the network to which a device belongs, and a host address is used to identify the device within that network.
- All devices included in one network have the same network address, and each device within the network can be identified by a unique host address.
- the meaning of one network refers to a range in which communication is performed between devices without a device connecting networks to networks, such as a router. If communication between devices needs to go through the same device on the router, then they are not on the same network.
- Subnetting means dividing an IP address into a network address part and a host address part in order to efficiently distribute limited resources to improve network performance.
- a broadcast domain that is too large can slow down packet transmission and cause performance degradation in a network environment. Therefore, communication performance can be guaranteed by dividing the network.
- An IP address can be expressed as a 32-digit binary number. That is, up to 2 ⁇ 32 addresses can be expressed. Since IP addresses are limited, you can prevent waste by using a subnet mask to assign only necessary network addresses as host IPs.
- the subnet mask basically consists of 1 and 0, and through this, it can indicate how many upper bits of the IP address are the network address.
- a subnet mask is represented by a binary number representing the network address portion of an IP address as all ones and the host address portion as all zeroes.
- the network address portion of an IP address can be obtained by computing the bitwise AND of the IP address and the subnet mask.
- the first bit to the 18th bit of the subnet mask are consecutively expressed as 1, and the 19th bit to the 32nd bit are consecutively expressed as 0. Accordingly, the portion from the first bit to the 18th bit of the IP address represents the network address part, and the portion from the 19th bit to the 32nd bit represents the host address part. Therefore, the network address part and the host address part of the IP address can be identified by referring to the bit information of the subnet mask.
- 4 is a reference diagram for explaining class A, class B, and class C IP addresses.
- class A IP addresses are used in large-scale network environments.
- the default subnet mask is 255.0.0.0. Since the host bandwidth is 24 bits, the number of hosts that can appear per network can be 2 ⁇ 24, that is, about 16 million.
- Class B IP addresses are used in medium-sized network environments.
- the default subnet mask is 255.255.0.0. Since the host bandwidth is 16 bits, the number of hosts that can appear per network can be 2 ⁇ 16, that is, 65000.
- Class C IP addresses are used in small network environments.
- the default subnet mask is 255.255.255.0. Since the host bandwidth is 8 bits, the number of hosts that can come out per network can be 2 ⁇ 8, that is, 256.
