and client of the computer for identification, as shown in Figure 5. The network connection used for client access is named "Public Address ", the network connection used for communication between nodes is named "private address ". · Enter the command "ipconfig/all" on the computer server to view the computer's IP address. 6 shows that the "Public Address" IP address is 192.168.0.2 and the "private address" IP address is 192.168.1.2. run the "
I. Differences between the three types of networks 1. vmnet0 Vmnet0 is actually a virtual bridge. This bridge has several ports, one for connecting your host, and the other for connecting your virtual machine. Their locations are equal, no one is the gateway. So in bridged mode, you can make the virtual machine the same as your host. 2. vmnet1 Vmnet1 is a host-only network mode, which is used to establish an isolated network environment. vmnet1 is also a virtual switch, and a port of the
: Enter the domain name of the site you cannot access. For example, if I enter www.jb51.net and cannot access it, DNS resolution may fail. We will receive a prompt message for DNS request timed out and timeout was 2 seconds. This shows that our computer does have a DNS resolution fault. TIPS: If the DNS resolution is normal, the correct IP address will be returned. For example, if I use the address www.jb51.net for query resolution, the name: jb51.net, addresses: 61.129.70.67, 61.135.133.104 i
system is Windows 2000 or above, and then press Start> RUN> Enter cmd to enter the command line mode. Step 2: Enter the ipconfig/all command to query network parameters. Step 3: In the ipconfig/all display information, we can see a place where DNS servers is written. This is the address of our DNS server. For example, the author is 202.106.0.20 and 202.106.46.151. It can be seen from this address that it i
