Differences and connections between MAC addresses and IP addresses (Computer Network)

host is moved from one network to another, you can give it a new IP address instead of a new Nic. (3) communication between computers in the LAN or Wide Area Network eventually means that data packets are transmitted from one node to another starting from the initial node on a certain form of link, finally transmitted to the target node. ARP (Address Resolution

Can I merge IP addresses and MAC addresses if I re-design the network?

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

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

Computer displays IP address conflict How do IP addresses conflict with other network systems

The main reasons for this situation are: 1, the local computer uses the 192.168.1.1 IP address, an

ATM Tutorial: Support for IP addresses in an ATM Network

overwrite model requires the definition of a new address system and related routing protocols. All ATM systems need to be assigned both the ATM address and the high-level protocol address to be supported. The ATM address space is logically separated from the address space of the top-level protocol, without any correlation. Therefore, all protocols running on the ATM subnet need some ATM Address Resolution

Bind multiple IP addresses to a single Nic for multi-network segment access, and bind multiple NICs to a single IP address for Load Balancing

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

How to determine if IP addresses in the network are stolen by arp Spoofing

Administrator familiar with batch processing commands can also edit a BAT command to complete a series of ping operations. The content of the BAT file is as follows: FOR/L % I IN (0,1, 255) Do ping X. % I-n 1 Arp-a> IP.txt This batch of processing files will be listed in the Active IP address and stored in the ip.txt file with their macaddress. Of course, the X. % I in the statement can be modified. For example, if the company
