network segment as the target host pc2. therefore, host PC1 sends an ARP request broadcast packet to the MAC address of 192.168.20.20. In this case, the router identifies the destination address of the report as another subnet (note that the IP address of the router interfa

Every week changes between the lab and the dormitory. The lab's damn public router locks the IP address. The Dynamic IP address is always an incorrect address, and can only be manually modified once. Then I was so lazy and didn't want to open the graphical interface to perfo

In network planning, the design of the IP address scheme is crucial. A good IP address scheme can not only reduce network load, but also lay a good foundation for future network expansion. This article discusses the IP address sch

This article describes the RedHat series (RedHat, Fedora Core, centos) and a method that is widely used in other Linux systems such as Gentoo.

address, NETMASK is the subnet mask, ONBOOT indicates automatic startup when the system starts. If you need to bind another IP address, You only need to add the file name and the eth0: x in the DEVICE in the file. LINUX supports up to 255 IP aliases 2. it is widely used to

1.1 IP Address authentication Multi-IP configuration Add an IP to a network card: (1) Enter the/etc/sysconfig/network-scripts/directory, cd/etc/sysconfig/network-scripts/ (2) Copy an IP template to the directory, where the Ifcfg-eth0 as the template CP Ifcfg-eth0 ifcfg-et

One Nic is bound to multiple IP addresses and multiple NICs are configured with one IP address. Commonly used is "one Nic is bound to multiple IP addresses" One Nic is bound to multiple IP addresses Linux network device configuration files are stored in/etc/sysconfig/networ

Article title: binding multiple IP addresses to an NIC in Linux to share a single IP address with multiple NICs. Linux is a technology channel of the IT lab in China. Some basic categories, such as desktop applications, Linux system management, kernel research, embedded systems, and open-source systems, sometimes need to bind multiple

Bind multiple IP addresses to a single Nic In CentOS and share one IP address with multiple NICs In centos, you sometimes need to bind multiple IP addresses to one network card. This article describes the Redhat series (redhat, Fedora Core, Centos) and a method that is widely used in other Linux systems such as Gentoo.

To do this, log in to SSH:Vi/etc/sysconfig/network-scripts/ifcfg-eth0:0The second IP is aVi/etc/sysconfig/network-scripts/ifcfg-eth0:1A third IP is theIfcfg-eth0:2 (from this analogy)Device=eth0:0 NIC device name Onboot=YES random start Bootproto= static statically assigned ipipaddr=*.* . * * the IP address to add ne

In Linux, you sometimes need to bind multiple IP addresses to a network card.

messy. Due to the fact that network applications are growing much faster than previously planned, the previously divided IP subnet and Vlan are not reasonable. Some units occupy a large number of IP addresses, but the usage is less than 10%, and some units even need additional subnets as their IP resources. If the pro

The IP addresses that have the same access behavior are uniformly divided into the same virtual work subnet, and the relevant routing policies are properly set up,
