What do you mean by 222, 221, 196, 65 at the beginning of the IP address? What s the point?

A slash after the IP address.

24 indicates that the mask bit is 24 bits. The mask is a string of binary.

**Perform bits and operations on the target field to mask the current input bits. The source code and mask are computed bitwise or logically.

Derive a new operand. Bitwise operations such as OR and AND are used. It is used for example, changing the uppercase letters in the ASCII code to lowercase letters.

Subnet mask. It is used to identify two IP addresses.

Whether they belong to the same subnet. It is also a 32-bit-long binary value of a set of wheels, and the value on each of them represents a different meaning: "1" means that the bit is a network bit; If it is "0", it means that the bit is the host bit.

As with IP addresses, people also use the dot decimal system.

to represent the subnet mask, for example: If two IP addresses are calculated with the same subnet mask and get the same result, the two IP addresses are in the same subnet. In other words, two computers with two IP addresses are like different departments in the same organization, and although they may have different roles, functions, and even geographic locations, they are both on the same network.

25 represents the mask i.e.

is the representative CIDR block.

A subnet mask is a 32-bit address that is used to mask a portion of an IP address to distinguish between network and host identities and to indicate whether the IP address is on a local area network or a remote network.

Determine the number of subnet masks: The number of bits used for subnet masks is determined by the number of possible subnets and the number of hosts per subnet. Before you define a subnet mask, you must figure out the number of subnets and the number of hosts that would otherwise be used.

The steps to define a subnet mask are:

a. Determine which group addresses are used by us. For example, the network number we apply for is ", the network address is a Class C IP address, the network identity is ", and the host identity is ".

b. According to the number of subnets we need now and the number of subnets that may be expanded in the future, the subnet mask is defined with some bits of the host. For example, we need 12 subnets now, and we may need 16 in the future. Use the first four bits of the third byte to determine the subnet mask.

The first four bits are all set to "1", that is, the third byte is "11110000", which we will call the new binary subnet mask for the time being.

c. Set each bit of the corresponding initial network to "1", that is, the first two bytes are set to "1", and the fourth byte is set to "0", then the discontinuous binary form of the subnet mask is: ".

d. Convert this number into discontinuous decimal form as: " This number is the subnet mask of the network.

The meaning of 0 to 25 is that is

Summary. 21044888 represents a Class C IP address.

A Type C IP address is a type of IP address in which the first three segments are network numbers and the remaining one segment is the local computer number. If the IP address is represented in binary, the Class C IP address consists of a 3-byte network address and a 1-byte host address, and the highest bit of the network address must be "110". In the Class C IP address, the length of the network identity is 24 bits, the length of the host ID is 8 bits, and the number of Class C network addresses is relatively large, with more than 2.09 million networks.

Suitable for small-scale LANs with a maximum of 254 computers per network.

What IP address does 21044888 represent?

Hello, I have seen your question, it is being processed<>21044888 it represents a Class C IP addressC Class IP address refers to the fact that in the 4 segments of the IP address, the first 3 segments of the number are network numbers, and the remaining 1 segment of the virtual number is the number of the local computer. If the IP address is represented in binary, the Class C IP address consists of a 3-byte network address and a 1-byte host address, and the highest bit of the network address must be "110". In the C IP address, the length of the network is 24 bits, the length of the host ID is 8 bits, and the number of Class C network addresses is relatively large, with more than 2.09 million networks.

Suitable for small-scale LANs with a maximum of 254 computers per network.

Refer to it. Hope it helps.

When a normal user surfs the Internet, the computer will temporarily obtain an address from the ISP's host as your computer's identification on the network, so that when there is a data transmission, other hosts can find you, just like the postman must know the address to deliver a letter.

IP addresses are uniformly assigned, and different regions have different address ranges, which is similar to the house number, which seems to be assigned to Africa (Afrinic)?

The number of computers in the world is far greater than the number of IPs that can be provided, so there are some IP addresses that are used exclusively for local area networks and are not used by hosts on the Internet network

Class A Class B Class C There are not many hosts in general homes or businesses, and Class C is enough, so you can see that the vast majority of LANs are **. I think that's what your problem should be, but you made a mistake when you set up the network. Of course, if this IP is never placed directly on the Internet, whatever network segment you use.

It's just that doing so can be confusing for the maintainer, especially if you need to set up a corporate intranet.

Zuluyang's answer is very good, I agree, the fact is that A, B, and C IP addresses are private addresses, also called private IP addresses, which are used for small-scale intranets.

It is a private IP and can only be used within the LAN.

Non-standard writing, no meaning, a variety of possibilities, one may be: refers to port 26, the other may be the last set of addresses may be 128 or 126, or 26

It means that this IP is divided by subnet, and the subnet mask is no longer there.

Hello, the IP address corresponding to this number is, and the corresponding city is Hong Kong SAR.
