how to block ip address from tracked

A few days ago to a client to do remote project implementation, the client side of the server is Windows OS, our business operation requires the Linux OS, so the Windows OS install VMware. However, when the IP address of the VM is configured, the problem of the dual NIC configuration IP address is encountered. Host is

arrays and is useful in network applications. The values of IPAddress. None and IPAddress. Broadcast are "Broadcast bandwidth 255.255", indicating that all IP addresses are 1. This address usually represents "Broadcast", indicating that data is sent to all devices on the Internet. Obviously, this is just an "Fantasy". Generally, routers do not forward such data packets.

whether the IP address is in the same CIDR block. Now, let's look at it.A company has 530 computers to form a peer-to-peer lan. What is the most suitable subnet mask and IP address?The subnet mask is not mentioned. The previous calculation result is 11111111.1111111100.0000

112.1600.10101000.20.0000.00000001Subnet Mask 11111111.111111.1111111111.00000000Obtain the and result 112.1600.10101000.00000000.00000000.Convert to 192.168.0.0 in decimal format. This is the network ID,Then, the subnet mask is reversed, that is, the IP address andThe result is calculated as follows: 2017.hangzhou.hangzhou.00000001, which is converted to a 10-digit system, that is, 0.0.0.1,0.0.0.1 indicat

VM dual Nic, so we have a problem. How can remote hosts communicate with the VM? In fact, it is very simple. We only need to configure a static route to the remote host on the VM. In this example, the IP address of the remote host is 192.168.33.250. Now we can add a static route to the VM, as shown below: Route add-net 192.168.33.0/24 gw 192.168.0.1 dev eth1 This command means to forward all data pac
