The so-called vro IP address, as the name implies, is the identifier of the vro body, just like the house number, to let the Data know from where to where, if the vro IP address is set incorrectly, then there will be problems with the network. How can we correctly set the router IP address? Here we will mainly introduc

data frame, and then check the MAC Address table to get out of the corresponding interface.IP address is effective throughout the network, the entire Internet network is the equivalent of a large map, also know how to get all the IP address, then in the transmission of the source IP and destination IP will not change.

Each Ethernet device has a unique MAC address at the factory, why do I need to assign an IP address to each host? or if each host is assigned a unique IP address, why should a unique MAC address be embedded in the production of a

For many friends, it is still a strange word to crack the network envelope routing. What does it do? What is its role? Let's take a look at these questions. It is said that on the Guangzhou side, China Telecom Netcom has begun to block route sharing and needs to purchase an Internet license. Whether this behavior is a monopoly or not, let's first think about it. Will it be our turn to block Guangzhou? Therefore, I shared an article about sharing and blocking, hoping to provide some help to my fr

I have learned about computer networks, MAC addresses, IP addresses, route forwarding, and routing.Algorithm. At the same time, we also understand that IP addresses are 4 bytes divided into A, B, and C networks, and D broadcast e is retained, indicating that the number of networks and machines are limited. With the increasing number of computers, more and more IP addresses are needed. The insufficient IP addresses indicate that there are so many netwo
