How can I tell where an IP address is?

You can check it on this website.

A lot of software, QQ** announcer can also be used, IP > address translation.

That's the post bar saved, so I won't let you see it.

Method: The correct IP address is a 32-bit binary number, which is usually split into 4 "8-bit binary numbers" (i.e. 4 bytes). IP addresses are usually expressed in the form of "dot decimal" in the form of (.

There is also a very important content in the IP protocol, that is, every computer and other equipment on the Internet is specified with a unique address, called "IP address". Because of this unique address, it ensures that users can efficiently and conveniently select the objects they need from thousands of computers when operating on computers connected to the network.

A Class A IP address consists of a 1-byte network address and a 3-byte host address, with the highest bit of the network address must be "0" and the address range is from to. There are 126 Class A networks available, each capable of accommodating more than 100 million hosts. It should be noted that the network number cannot be 127, because the network number is reserved for circuit and diagnostic functions.

Class B IP address.

A Class B IP address consists of a 2-byte network address and a 2-byte host address, with the highest digit of the network address having to be "10" and the address range from to to. There are 16,382 Class B networks available, each capable of accommodating more than 60,000 hosts.

Class C IP address.

A 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". There are more than 2.09 million networks ranging from to class, and each network can accommodate 254 hosts.

There are generally three types of addresses that are commonly used.

First determine whether it is made of 4 numbers with a dot"."Separate, and then determine whether the decimal system of each number is between 0-255, and meet the conditions is the correct IP address.

IP addresses are used to give computers on the Internet a number. The daily situation is that every networked PC needs to have an IP address in order to communicate normally. "Personal computer" can be compared to "a **", then "IP address" is equivalent to "**number", and the router in the Internet is equivalent to the "program-controlled switch" of the telecommunications bureau.

An IP address is a 32-bit binary number that is usually split into 4 "8-bit binary numbers" (i.e. 4 bytes). IP addresses are usually expressed in the form of "dot decimal", where a, b, c, d are decimal integers between 0 and 255. Example:

Analysis: 1What is a network.

A network is a set of multiple computing devices connected by a communication medium, and the scope of the network can be as small as a workgroup of a financial department or extended to all the computers of a large company, such as the network of a general company. From an address management perspective, all computers on a network should be managed by the same organization. If you send information to a computer, you should identify the computer by its IP-address and know that the IP-address has been assigned to the company.

By locating the network number, the IPNet is able to locate the computing resources in the company.

A network is identified by a network number. The network number is actually the IP address, which can be used to identify all the IP resources within an organization. The network is very large, so you need a large number of addresses.

The network is small, and the number of addresses required is relatively small. Some networks even require only a few network numbers.

2.What is Hosting.

The host, in layman's terms, is a computer in a network or unit. Take Class C IP as an example:

You can see a 3 2-digit Type C address. The first 2 and 4 bits of a Class C address represent the network number of the dead key, and the remaining 8 bits can be modified by the user who manages the network address. These 8-digit addresses represent the addresses on the "local" host.

Since the first three digits of a Class C address are 110, the network number of a Class C address starts from 1 9 2 and ends with 2 2 3. In Class C addresses, the 2nd and 3rd dot decimal numbers are also part of the network number. The size of the 8-bit address space managed locally by each Class C address network is 2 8 (or 2 5 6, but the IP address stipulates that the first and last IP addresses of each network are reserved addresses, so the actual number of available host addresses for each network is 254).

The network you mentioned is the network network host, saying that the first three digits of Class C IP are the network number, and the last digit is the host number.

Well, having said all that, what else is there not to understand can q***

Each IP address consists of two parts, the network number and the host number.

Internic divides IP addresses into five categories, Class A reserved for ** institutions, Class B for medium-sized companies, Class C for anyone who needs it, Class D for multicast, and Class E for experiments, with different types of addresses that can be accommodated.

Characteristics of Class A, B, and C IP addresses: When writing IP addresses in binary form, the first digit of Class A addresses is always O, the first two digits of Class B addresses are always 10, and the first three digits of Class C addresses are always 110.

Reserved addresses in IP addresses: The IP addresses of all 0 hosts are reserved for network addresses, the IP addresses of all 1 hosts are reserved for broadcast addresses, and the 224-255 parts are reserved for multicast and experimental purposes.
