The PC local loopback address 127.0.0.1 is often referred to as the local loopback address (the loop back addressing), which represents the device's local virtual interface, so the default is seen as an interface that never goes down. also has a similar definition in the Windows operating system, so it is usually possible to ping this local loopback address
let's start by understanding the following basic concepts :1. Forwarding: represents the process of selecting a path for a group2,IP forwarding: Its traditional method is IP routing (IP routing), IP forwarding it is to send the datagram to select the path.3, Group:(most computer networks can not continuously transmit a

Broadband Line (household network cable or from the modem out of the network) needs to be connected to the router's WAN, the wired computer should be connected to the LAN port, the following figure:
If the line connection is correct, but the WAN port LEDs are not lit, check the WAN port wiring for bad contact, and try replacing the network cable that connects

Note: When powered on, the router is working normally with the SYS LEDs flashing, WAN LEDs illuminated steady or blinking, and the 1/2/3 port LEDs attached
Each Ethernet device has a unique MAC address at the factory, why do I need to assign an IP address to each host? or if each host is assigned a unique IP address, why should a unique MAC address be embedded in the production of a
-area networks in recent years, and because of the high performance of routers, the price has dropped to close to the bridge, so routers are used more and more in LAN interconnection. A router is a network device that connects multiple networks or segments, which can "translate" data between different networks or segments so that they can "read" each other's data to form a larger network. Routers have two typical functions, namely data channel functio

Static IP is divided into two types, one is long-term fixed to a computer or route to use the IP address, General fiber network, or through the fiber or network cable connected to the domain will adopt fixed IP. The other is that no lines are connected to the Internet by a fixed IP
Router tplink882 How to set IP bandwidth functionality:
A user needs to ensure that the Intranet desktop games, video normal application, other terminals can normally browse the Web, QQ chat and other basic applications. The subscriber line is 4M ADSL line (uplink bandwidth 512Kbps, downlink bandwidth 4096Kbps). Combined with user requirements and total bandwidth, the allocation rules are as follows:
In the development, sometimes we need to send remotely, or through 3G and 4G, or other WiFi environment to send a small amount of data, and do not want to spend so much cost to develop a cloud server, this time the emergence of a router to expose an intranet IP for external network access. In fact, the implementation name of this method is called port mapping .
Next we implement this way ready you want t

Each system accommodates a maximum of 2 hosts with 9 (host number 9) times = 512.3, an IP address is assigned to each office, and a router is configured to exchange this IP
When using a vro, you often forget the IP address of the Alpha router and cannot find the instruction manual for a while. What should we do? The following describes the six common Alpha router IP addresses. I hope this article will help you get what you want.
