knowledge.IPV4 can be divided into A,b,c,d,e5 class addressesThe reason for the classification is to better manage and apply the IPV4 address, a IPV4 is divided into network bits and host bits. For example 192.168.1.1/24, this IP address is followed by A/24, indicating that the first 24 bits are network bits, and the last 8 bits are the host bits (remember the b

The remaining downlink 7Mbps bandwidth resources will be idle and will not be allocated to. 10 and. 11 unless the maximum available downlink bandwidth is changed to larger, otherwise they will not be able to use the remaining bandwidth. When IP QoS is configured, the mode is selected for shared bandwidth, which is the ma

When the internetwork was originally designed for easy addressing and hierarchical construction of the network, each IP address consisted of two identification codes (IDS), the network ID and the host ID. All hosts on the same physical network use the same network ID, and one host on the network (including workstations on the network, servers, routers, etc.) has a host ID corresponding to it. The Internet C

is set to 32bit, the value range is 2 of 32, a total of "4294967296" IP address.The IP address is divided into four segments, each section 8bit, if converted into decimal, the range of the value of each paragraph is from 0~255The computer will generally translate the

network, when a local area shows high growth or the overall network scale is increasing, at this time, unreasonable planning is likely to have to re-deploy a local IP address or even an overall IP address, which is not a simple task in a medium or large network. Here, we will briefly describe the concepts of

private IP addressing Automatically configures the TCP/IP protocol for a single network segment without a DHCP server. By default, a computer running Windows 98/Me/2000/XP first tries to contact the DHCP server in the network to obtain its IP address and other information from the DHCP server, and configure the TCP/

Internet network, a gateway is an intermediary device that connects an intranet to other networks on the Internet, also known as a "router." The gateway address is a channel address that can be understood as the transmission of Intranet and Internet network information. According to different classification standards, there are many kinds of gateways. The gateway in the TCP/

This document uses the KV2004 firewall as an example to describe how to search the IP addresses of friends of the other party: Considering that QQ chat with friends is performed through UDP protocol, you must first set up a KV firewall to automatically m

IP is a powerful network configuration tool in the Iproute2 package, which can replace some traditional network management tools. For example: ifconfig, route, etc.,The above example can be fully implemented with the following IP commands, and

(changing all 0 bits to 1 and vice versa) and bitwise OR operations with the address (or equivalent network/subnet prefix) of any computer in the subnet.Historically, the use of broadcast addresses as destination datagrams is also known as directed broadcasts . At least theoretically, this broadcast can be routed over the internet as a single datagram until it reaches the destination subnet, and is sent to all hosts in the subnet as a set of broadcas

the current solution can be grouped into the following three categories: 1. Write yourself: with '. ' Divide the IP string into substrings, and then judge whether each character of each substring is a number, and finally converts it to a value to determine whether it is in the 0~255 range. /* Function: Determine whether the IP
