The broadcast address of the 201 1 0 1 21 network segment is:

IP address," and the 30 after " indicates that its subnet mask consists of 30 binary "1s" and 2 binary "0s", and its subnet mask is calculated to be .

Calculation method of network address The binary value of the subnet mask and the binary value of the IP address are logically and arithmetic, and the result is that the network address is calculated to be .

The broadcast address is.

Summary. Dear, you can also learn about the following: The IP address is composed of 32-bit binary numbers, and the front part of the IP address represents the network part, and the back part represents the host part.

A subnet mask is a 32-bit binary number of the same length as the IP address, where the network portion is a consecutive 1 and the host portion is a continuous 0. In this problem, the subnet mask is , which is converted to binary, where the first 19 bits are the network part and the last 13 bits are the host part. The binary form of this IP address is 19 bits from left to right, which is the network part, and the next 13 bits are the host part.

Converting the network part to decimal is , i.e., this address is the network segment in which it is located. The last binary 1 address of the CIDR block is the broadcast address of the subnet.

Write the following number to take the address, the number of the network segment where it is located, and the broadcast address in the subnet.

Dear,Hello [Flower Call],,The network segment where it is located is,The address of the high and simple Guangqi chain pants broadcast in the subnet is Oh。

Dear, you can also take a rough look at the following: The IP address is composed of 32-bit binary numbers, and the front part of the IP address represents the network part, and the back part represents the host part. The subnet mask is a 32-bit binary number with the same length as the IP address, where the network part is a continuous 1 and the host part is a continuous 0.

In this problem, the subnet mask is , which is converted to binary, where the first 19 bits are the network part and the last 13 bits are the host part. The binary form of this IP address is 19 bits from left to right, which is the network part, and the next 13 bits are the host part. If the network part of the friend exchange is buried in the decimal system, it is, that is, this address is the network segment where it is located.

The last binary 1 address of the CIDR block is the broadcast address of the subnet.

Summary. The network address range is to. This broadcast address range is:

The network address and broadcast address of the CIDR block.

The network address is cleared within the scope of the answer. The range of the broadcast address of the object is .

Fellow, I really didn't understand, I can be more specific.

Indicates that the subnet mask where the IP address is located is 21 bits, that is. This means that the first 21 bits are network bits and the last 11 bits are host bits in the network address of the subnet. The network address is calculated by logically and arithmetrically combining the IP address with the subnet mask.

For example, after performing logic and operations, the result is that this is the network address of the subnet. The broadcast address is the address where the last available host address is located. The last available host address can be obtained by setting all host bits of the network address to 1.

In that subnet, the last available host address for hall width is, so the broadcast address is. In summary, the network address is and the broadcast address is.

The network address and broadcast address of the CIDR block.

Hello! is a CIDR (Classless Inter-Domain Routing) notation that represents an IP address range, where "21" indicates that the subnet of the address segment is a code of 2048 IP addresses. To calculate the network address and broadcast address of the CIDR block, we need to find the first IP address and the last IP address of the CIDR block.

The first IP address is and the last IP address is. Next, we need to determine the network address and broadcast address of the address segment. The network address is the first IP address in the CIDR block, ie.

The broadcast address is the last IP address in that address block, ie. Therefore, the network address is and the broadcast address is. It should be noted that the IP address in this CIDR block is from to, with a total of 2048 IP addresses.

Hello, glad for your question, for a given network segment, the broadcast address of the network segment can be calculated by the following steps: 1. Determine the subnet mask: The given network segment is 27, which means that the subnet mask is converted to binary form:

The number of host bits converted to binary is confirmed: Since the last 5 bits of the sub-net's mask are 0, it means that there are 5 bits as the host bits. 4 Calculate the broadcast address:

The broadcast address is the IP address or address obtained by setting all host bits to 1, that is, in a given network segment, all host bits are set to 1, and the broadcast address is obtained. Therefore, the broadcast address of the network segment is.
