How to calculate the network addressIn our daily life, we can see from the literal that the street address is North Street, but we cannot see the network address from the IP address. We need to calculate the network
records the correspondence between the host IP address and the MAC address. ARP: ARP is a network-layer protocol that resolves IP addresses to MAC addresses. For example, explain in detail how ARP works. 650) this. width = 650; "title =" 3.jpg" src = "http://www.bkjia.com/uploads/allimg/131227/01020Q302-2.jpg"/> 1) if host A wants to send data to host B, host A
In the network, addresses are the basis of our applications. Address-related attacks often occur. So how can we effectively stop this problem? This should start with the ARP Address Resolution Protocol. This article describes the application and principle of the Protocol. 1. interchanging network sniffing The ARP
Rotten mud: Change ESXI5.0 management network card and Management IP address, esxi5.0ip This article was sponsored by Xiuyi linfeng and first launched in the dark world. The company's servers are basically in the IDC room, in order to make better use of server performance. So there are several servers installed with ESXI5.0 for virtualization. Note that these servers are currently dual NICs. Because the

Here, let's take a look at three common types of IP addresses.Class a ip segments 0.0.0.0 to 127.255.255.255Class B IP segments 128.0.0.0 to 191.255.255.255C-type IP segments 192.0.0.0 to 223.255.255.255The default subnet mask allocated by XP is only 255 or 0 for each segment.Class A
common one is NAT (Network Address Translation), a computer in a sub-Network, only a few hosts (usually only one) can directly connect to the Internet. IP addresses of hosts in different subnets can be repeated. When computers in the subnet need to access the Internet, they need to be "forwarded" by computers directly connected to the Internet in the subnetwork
4. Proxy server allocation Although the NAT address translation method is good, it also has its own shortcomings. Simply put, you can only perform IP address translation simply, but cannot implement file caching. This reduces Internet access traffic and prevents fast Internet access. The proxy server works differently from the NAT server. Instead of simply performing
The complexity of the network structure also makes it difficult for us to maintain some of its services. Sometimes, some faults may inevitably occur. Here we will mainly explain the problem that the client in the DHCP relay fault cannot obtain the IP address of the same network segment as the IP address through the rel
The commercialization of IPv6 networks has played a key role in promoting IPv6 networks. Now, as an IPv4-dominated network. Many of us are still unclear about the IPv6 network address. Now let's take a look at the knowledge of IPv6 network addresses based on its installation problems. IPv6 and IPv4 are two completely d

In some wireless networks, because of the large number of clients, to facilitate the management of these machines, many administrators use the DHCP service provided by the wireless router to provide clients with TCP/IP parameter configuration, such as IP address, gateway address and DNS server. However, if your wireless network, some computers must manually speci
