Differences and connections between MAC addresses and IP addresses (Computer Network)Recently, I took a test and always encountered mac address problems. So I did some research online.

I read books related to network basics a while ago. I had a question: Why do I have a MAC address and an IP address? Can the two be combined into one? The current logic is as follows: During data transmission, the vro can view the IP address of the data packet and compare it with the "IP Set: Next Hop MAC address" reco

If you have an IP address of class C, such as 192.168.10.0, you want to divide it into eight CIDR blocks. Each CIDR block can contain 32 hosts,Subnetmask: zookeeper Upload Failed:192.168.10.0-31, network address: 192.168.10.0, broadcast address: 192.168.10.31192.168.10.32-63, network address: 192.168.1

This situation is mainly due to other computers under the router is also using your computer's IP address, resulting in IP address conflicts, there is no access to the Internet and so on.
The main reasons for this situation are:
1, the local computer uses the 192.168.1.1 IP address, an

Today, we have encountered the problem of implementing multi-network segments in Linux. In the past, we only had to pay attention to how to modify the Linux route. When using the 2003 system, we often access multiple network segments with a single Nic. The premise is to bind an IP address for each CIDR block first. Similarly, if we need to enable the Linux Nic to
service quality can be shared by other protocols or applications.Although LANE provides an effective way to bridge between subnets in an ATM network, services between subnets still need to be forwarded through routers. Therefore, an ATM router may become a bottleneck, the MPOA mentioned below will solve the problem of inter-subnet communication efficiency. Iii. CLIP (ClassicalIPoverATM)1. PrincipleTo run IP
