Find the exact IP address. Urgent! Urgent! Urgent!

It is not possible to know the exact address.

Only under special circumstances can an application be made to the public security organ or telecommunications.

Henan Zhengzhou Telecom|This should also be accurate to the district, because telecom has already allocated a number of IP bands to each province.

Each province is assigned a number of IP segments to each city.

Each municipality is assigned a number of IP segments to each district (not all). For example, Nanhai District, Foshan City, Guangdong Province, China).

When you arrive in the city (district), you will be randomly assigned an IP (broadband connection) to each person who goes online, so every time you connect to the Internet again, the IP is different.

I'm sorry, there's nothing I can do

Telecom uses DHCP servers to divide IP addresses

This IP may have been used by n people by now.

If you want to know the specific information, you can bring the IP address, bring the time period when the IP was online, and go to the database of the DHCP server of the telecom If the telecom is run by your family, haha· Good luck

First of all, the IP address you gave to the computer is wrong, it is a network address, which means a lot of IP addresses, this should be the CIDR protocol address, if there is this address protocol, then the ABCDE class address is meaningless, the C class address has 2 8 addresses, and the maximum number of hosts is 254, so you better take a good look at the question, is it wrong.

1 The 24-bit mask indicates that the first three segments are the network address and the last segment is the host address, so the third segment can be calculated.

2 183 is made into binary 10110111

3 The 16 addresses should be from 10,110,000 to 101111114 i.e. from 176 --- 191

So its IP range is from.

16 C-> A C is 24 16 is 2 4, and 16 C's correspond to 20 questions become.

That's easy to calculate.

host min

host max

The use is great. You think of it as the address of your computer for network management.

2.Yes. 3.

When IP is set. There's something called a subnet mask. It is also composed of four sections.

And it is composed of two numbers, 255 and 0. It is the one that determines the IP network segment. For example, if the subnet mask is and the IP address is ***, it means that the first three segments of the IP address must be the same as the first three digits of the gateway IP.

The last digit can be 0 255 any number (cannot be repeated with other machines)...If the subnet mask is set, the first two digits of the corresponding IP address must be the same as the first two digits of the gateway IP address, and the last two digits must be the same, and the number between 0 and 255 can be arbitrarily selected. That is to say, if the subnet mask corresponds to the IP address, if it is 255, the value of this IP segment must be the same as the number corresponding to the gateway IP segment, if it is 0, you can take it arbitrarily.

4.There are many reasons for this, and your machine may be due to IP address conflicts. IP addresses within the same LAN are unique.

If the IP address of a computer is specified to be set upright instead of being obtained automatically. And you turn on the computer first, you automatically call your brother to get the IP address specified by the other Zhixing computer when you get the IP, and when the other computer is turned on, it causes an IP conflict. So as long as you change an IP, it's fine.

Another possibility is that the router or network management software assigns a certain IP address to a certain MAC address (the physical address of the network card), and you want to obtain this IP, so the router or network management software rejects your IP address.

5.Because you are using the same wireless configuration, of course the IP address is the same.

1.Class number 101 and student number 04, from which the IP address range can be determined. There are 16 people in the technical department, because the subnet needs to occupy 1 network address and 1 broadcast address, take the closest value, so it is 2 to the 5th power, that is, 27,.

There are 30 people in the sales department, and 32 IP addresses are required to go to the beginning and tail, which is 2 to the 5th power of 27. There are 8 people in the personnel department, and there are 10 people in the head and tail, so it is 2 to the 4th power 28. There are 4 people in the finance department, and the head and tail are 2 to the 3rd power 29.

2.Before planning, the default subnet mask was class); After the planning of the cherry blossoms, the technical department, the sales department, the personnel department, the finance department.

Pure hands to beat the blind macro, hope.

Hope it helps.

A Class B network address is a 16-bit subnet by default.

The network bit borrows one bit from the host bit to divide two subnets, borrows two bits to divide four subnets, borrows three bits to divide eight subnets, and borrows four bits to have 16 subnets. The subnet mask is changed to 20 bits

255 into binary is 11111111

That is, a total of 32 1s is the maximum 32 bits of the subnet mask.

11111111 from the left, the first 1 is 2 to the 7th power = 128, and the second 1 is 2 to the 6th power = 64 、..The rightmost 1 is 2 to the power of 0 = 1

Written in decimal system, it is 128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 = 255

If the Class B network is to be divided into subnets, it needs to borrow a bit from the host, and if it is divided into two subnets, it will borrow one bit from 16 to 17

Binary writing has a total of seventeen 1s

Decimal writing.

Borrowing seventeen digits, the decimal system is written as 128, and the subnet is divided by 128.

is the first subnet.

is the broadcast address of the subnet.

is the second subnet.

is the broadcast address of the subnet.

For example, if the question is divided into 16 subnets, you need to borrow 4 subnets to borrow 20

Binary writing.

Decimal writing.

The position of the last 1 in binary corresponds to 16 in decimal system for Xiaohui, and every 16 increase in the network address is the network address of the next subnet. From the binary of the above 20 subnet masks, it can be seen that the host bit has 12 bits, that is, 12 zeros, and each subnet has 4096 addresses, and each subnet removes a network address and a broadcast address, leaving 4094 addresses available.

Or you can use 256-240 to get 16, because each segment is 0 to 255, a total of 256 numbers, there are many ways to use whichever is suitable for your memory.

The specific Bi clan is as follows.

Network address. Available address ranges. Broadcast address.

1. Whether it is unique or not, this is not necessarily, it may be that the private address assigned to you may be connected, and it is not unique in the world at this time;

2. The IP address is really insufficient, so there is IPv6, which is composed of 128-bit binary numbers. The metropolitan area network address of each country is generally a public address, unless he wants to be independent of the world Internet;

3. The global IP addresses are uniformly divided, and ICANN is responsible for them, and the addresses are unevenly distributed across countries, with the United States accounting for the majority. The public server IP address is applied for step by step, 4, the server generally has a good memory domain name, such as.

You can access it by returning the IP address through DNS (Domain Name Resolution).

Category C address: Guess the range from 192-223, for example, the first, second, and third segments of the number are network numbers, and the remaining last segment of the number is the number of the local computer. Converted to binary, 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 spike network can accommodate 254 hosts.

Distinguish by subnet mask:
