Editor to share with you the reasons why the intranet ping is not connected to the ip address, I believe most people do not know much about it, so share this article for your reference. I hope you will learn a lot after reading this article. Let's learn about it together.

The reasons are: 1, the other party has been turned off, or the address does not exist on the network; 2, the other party is not in the same network segment and cannot be found through routing; 3, the other party does exist, but set up ICMP packet filtering; 4, set the IP address error; 5, the protocol installation is not normal, can not send and receive ICMP packets.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

The reasons are:

1. The other party has turned off the phone, or there is no such address on the network at all.

2. The other party is not in the same network segment as himself, and the other party cannot be found through routing.

3. The other party does exist, but ICMP packet filtering is set (such as firewall settings).

4. Set the IP address incorrectly.

5. The protocol is not installed properly and cannot send and receive ICMP packets.

Extended data:

The principle of ping

Send a packet of a certain length to a specified network address, according to the convention, if the specified network address exists, it will return a packet of the same size. Of course, if it is not returned within a certain time, it will be a "timeout". Will be considered that the specified network address does not exist.

The ICMP protocol is sent over the IP protocol, which is a connectionless, unreliable packet protocol. In Unix/Linux, the sequence number starts at 0 and is incremented in turn. The ICMP serial number of the Windows ping program is irregular.

ICMP protocol packet in actual transmission: 20 bytes of IP header + 8 bytes of ICMP header + 1472 bytes of 38 bytes.

ICMP message format: IP header (20 bytes) + 8-bit type + 8-bit code + 16 checksum + (different types and codes, different formats).
