, infrared, etc., sometimes referred to as physical media. The MAC address is also called the physical address, hardware address, or link address, which is written by the network device manufacturer when it is produced inside the hardware. This address is not related to the network, that is, regardless of the hardware with this address (such as network cards, hubs, routers, etc.) access to the network where, it has the same MAC address, MAC address is generally immutable, can not be set by the u

First of all, our premise is the local area network, so we mentioned the modification more specifically, is to find the subnet mask and the default gateway for proper padding. Here are two specific ways to do this: Method One, we find any other networked computer on the same LAN, locate and double-click the local connected Internet Protocol (TCP/IP) entry, and populate the

Network Segment Encyclopedia business cards A cidr Block refers to the part in a computer network that uses the same physical layer device (transport medium, repeater, hub, and so on) for direct communication. From one IP address to another, it is like a network segment from 192.168.0.1 to 192.168.255.255. Network Segment The subnet mask assigned by the IP address is only 255 or 0 in each segment by defa

places, while the number of hosts is too small, therefore, the host addresses it provides become increasingly scarce. Currently, in addition to using NAT to allocate reserved addresses within an enterprise, a high-category IP address is usually further divided, to form multiple subnets, which can be used by different user groups. This is mainly to effectively use the IP address in the case of network segmentation. By taking the high part of the host number as the

You must know something about the IP address, right? We know that the TCP/IP protocol that is widely used in the Internet is to differentiate between different hosts by using IPs. If you've ever had a TCP/IP protocol set up, then you're bound to encounter the term subnet mask (Subnet mask), so do you know what a

To configure the default gateway, you can create a default path in the IP route ta

method One: First locate any other networked computer on the same LAN, and then double-click the Local Internet Protocol (TCP/IP) entry, and fill in the default gateway and subnet mask inside the computer. 　　Method Two: 1, find the same LAN other normal operation of the computer, click on the Win+r key combination, in the pop-up dialog box directly input cmd, and then click Enter; 2, came to the
