    First, enter cmd in the start-run, enter the doc mode and enter: ping is in the network state.

    Pinging

    Has 32 bytes of data:

    Reply from : byte = 32 time = 25ms ttl = 52 reply from : byte = 32 time = 23ms ttl = 52 reply from

    bytes=32 time=21ms ttl=52 replies from :bytes=32 time=21ms ttl=52 ping stats:

    Packets: Sent = 4, Received = 4, Lost = 0 (0% Lost), Estimated time (in milliseconds) for round trip:

    Minimum = 21ms, Maximum = 25ms, Average = 22ms not networked.

    Pinging data with 32 bytes:

    Reply from : Unable to reach target host.

    Reply from : Unable to reach target host.

    Reply from : Unable to reach target host.

    Reply from : Unable to reach target host.

    ping stats:

    Packets: Sent = 4, Received = 4, Lost = 0 (0% Lost).

    1. First of all, judge whether it is made of 4 numbers with dots"."Separate, and then determine whether the decimal system of each number is between 0-255, and meet the conditions is the correct IP address. 2. IP addresses are used to give computers on the Internet a number.

    The daily situation is that every PC connected to the Internet needs to have an IP address in order to communicate properly. The "personal computer" can be compared to "a **", then the "IP address" is equivalent to the "** number", and the router in the Internet is equivalent to the "program-controlled switch" of the telecommunications bureau. 3. The IP address is a 32-bit binary number, which is usually divided into 4 "8-bit binary numbers" (that is, 4 bytes).

    IP address, is written with ". ."The 4 decimal numbers separated by the range are 0-255, and if you exceed the range, it is invalid.

    In general, IP address classification is determined by the value of the first octet, and any network address between 0 and 127 is a Class A address. Any network address between 128 and 191 is a Class B address. Any network address between 192 and 223 is a Class C address.

    The network address of any first octet between 224 and 239 is a multicast address, i.e., a Class D address, which is reserved for Class E.

    IP addresses have their own specifications and are 32-bit, such as:

    The IP address is divided into four segments, the first two are the network address, and the last two are the host address.

    Answer the legal steps to determine the IP address: 1. First understand what the IP address is, and the IP address is divided into Class A, Class B, Class C, Class D, and Class E. The IP address range for Class A is, Class B is, and Class C is.

    2.Then judge the length of the ID card. In Class A IP addresses, the length of the network ID is 8 bits, the length of the host ID is 24 bits, and the subnet mask is class, which is suitable for medium-sized networks with a network ID length of 16 bits, a host ID length of 16 bits, and a subnet mask.

    Class C is suitable for small LANs with a network identity length of 24 bits, a host ID length of 8 bits, and a subnet mask.

    3.Finally, judge whether it is legitimate. Out of each legitimate IP address, there are four that start with "."

    3 separate digits, each between 0 and 255, including 255. I believe that after studying, we already know how to tell if an IP address is legitimate.

    Get the IP address of your computer.

    To determine whether two IP addresses belong to the same network, the first thing you need to know is the IP addresses of the two computers at this time. Here is an example of how to view the IP address of the Windows system, and the method of viewing the IP address of other systems can be. It doesn't matter whether the same network or system is the same, you just need to know the IP address.

    Run the cmd command.

    Line program: shortcut keys for other programs in order to hedge risks.

    First, go back to the Windows system desktop, press the shortcut key combination (Ctrl+R) to open the system runner entry, enter cmd in the pop-up interface and press enter (or click the mouse OK button).

    Check the IP address of the machine: Type 'ipconfig' in the cmd command line program that the system opens and hit enter. The system outputs a string of basic information about the local network link (Windows IP configuration information).

    The IPv4 address is followed by a number separated by 3 decimal points.

    Subnet mask. Control the number of different IP addresses on the LAN: You can check the Windows IP configuration information to know how many different IP addresses are in the currently linked LAN.

    The subnet mask is a mask by default, which means that the first three positions have been fixed, and there are up to 255 IP addresses. If the subnet mask is , then the IP address is 255x255=65025Generally 255 is enough.

    Determine the same network segment: If the Windows IP configuration information of two computers is the default gateway.

    If the IP addresses are the same, and only the values of the last interval are different, then the two IP addresses are in the same network segment (belonging to the same network as Qiyouqiqi). For example, it is the same network segment as .

    Verify whether two computers on the same network can be linked to each other: You can see whether two computers belong to the same network by the IP address, if you need to verify whether two computers on the same network can be linked to each other, you can enter ping in the cmd command line (there is a space here, such as ping the other IP address, hit enter. The input information shown in the figure below indicates that the two calculators can be found with each other.

    1. Explain the ping command.

    Take IP as an example.

    Speak cmd speak the command and enter ping

    The results are shown below.

    Lecture T Affair.

    Talk talk No, the thing is, the IP is being used, and the computer is mine.

    Lecture What's going on? Now, I'm going to use another method to determine whether the IP talk is really not there.

    ARP Talk Talk Existential Opinion.

    Lecture

    Lecture T do yes is the calculator in the network , in order .

    Speak and talk But can you really defend yourself? The answer is no.

    Talk Talk Talk I can use the ARP Talk Here's how:

    In the cmd Lecture command.

    arp d speaks about the reply.

    arp a talk about the reply.

    The results of the lecture are as follows:

    Talk talk

    Lecture

    Talk about it, talk about it. This is shown below:

    Talk But when I get into the arp a lecture again the arp talk command will have one more in my arp lecture store.

    Talk about it , talk about it Its physical address (NIC address) is also included in your ARP Lecture memory.

    Speaking about it, you can conclude that the IP must be being used.
