NAT principles of IPv6 and MAP66 1. Why is NAT not recommended in IPv6 standards? This is a problem. As I explained earlier, IPv4 NAT breaks the Internet's "interconnection" feature, making some IP addresses no longer accessible in two directions, NAT adds a direction to the IP protocol without direction, especially the stateful NAT type. However, IPv4 NAT is designed to save IP addresses, rather than addin
Experiment topology of ipv6 Network Protocol Configuration:Tutorial objective: (1) configuring rip Protocol in ipv6 (2) configuring ospf protocol in ipv6 (3) configuring ospf protocol in ipv6 (4) let the two ipv6 networks pass through ipv4 network communication (Tunnel) www.
For a complete IPv6 address, need to write 128 bits, has been divided into 8 paragraphs, 4 characters each, that is, the complete representation of a IPV6 address, need to write 32 letters, which is quite long, and easy to confuse and error, so IPv6 in the representation of the address, is fastidious, so far, IPV6 addr
How to disable IPv6 in CentOS 7
Recently, a friend of mine asked me how to disable IPv6. After searching, I found the following solution. The following describes how to disable IPv6 on my CentOS 7 mini server.
You can do this in two ways.Method 1
Edit the/etc/sysctl. conf file,
Vi/etc/sysctl. conf
Add the following rows:

IPv6 URPFUnicast Reverse Path Forwarding, unicast Reverse Path Forwarding) is an IPv6 unicast packet detection and judgment technology used to prevent Network Attacks Based on source address spoofing.
IPv6 URPF is used in an IPv6 network. by obtaining the IPv6 address and t
For IPv6 translation, the new saying is: "The Dual stack can be used where the dual stack can be used, and the tunnel is used where the tunnel has to be used ."
Users are concerned about how to migrate data from IPv4 to IPv6. In the current application, IPv6 mainly uses the migration technology that covers every IPv4 upgrade case, however, many migration technolo
The use of IPv6 network protocols is no longer a new thing. However, as an excellent improved version, it does have shortcomings, which is why it has not been popularized for so many years. Next we will analyze his advantages and defects, and then give a brief introduction to his installation.
In Windows Server 2003, Windows XP Service Pack1, and Windows XP Service Pack 2, Microsoft has bound Internet Protocol version 6 (
IPv6 anycast Technology and Its anycast Address Resolution Protocol
Author: Wang Jianli fangwei
Abstract: anycast is a new network application. Anycast communication supports service routing. However, many definitions of anycast communication in IPv6 are vague, and no protocol standards have been reached in controlling routes, therefore, anycast communication between nodes cannot be implemented. In this
1. hardware or software?
Most vrouters and vswitches support IPv6, but these network devices have different forwarding rules. A high-capacity core router processes data packets on its dedicated hardware (such as a dedicated integrated circuit or network processor) to accelerate IPv4 forwarding. However, the hardware architecture usually does not support IPv6. this means that the router processes
The IPv6 network protocol has been in use for many years, but it has been accepted in recent years. Now let's analyze the IPv6 protocol applications related to Microsoft and windows systems. Now let's take a look at the following content. In Windows Server 2003, Windows XP Service Pack1, and Windows XP Service Pack 2, Microsoft has bound Internet Protocol version 6 (IPv
First, the problem is:
Because local schools for the future promotion of the transition simplicity and their own internal network address updated to the IPV6, Therefore, it is often necessary to resolve IPV6 address to visit the site. But recently I have been aware of some of the school's internal site can not access the error prompted, experienced statistical awareness of these sites are equipped with
The method of configuring IPV6 under Windows 7 is basically similar to Vista, in view of the need for users to use the author to organize two articles on IPV6 under Windows 7, I hope to help users. (Note, in view of the different network configuration environment of each campus or other place, if the configuration is not successful according to the following method can further consult the relevant network m
With the current expansion of mobile devices, more and more communication devices need to access the network under mobile conditions, whether in the process of moving or after moving the region. Therefore, as an important part of IPV6-Mobile connection characteristics is also the important reason for IPv6 popularity.
How to solve mobility problems
IPv6 to solve
IPv6 is often compared to a small island, and IPv4 is compared to the ocean. In fact, we will also use different methods and technologies to complete the transition from IPv4 to IPv6. The real islands and oceans do not exist, because the network itself is connected. What's more, the two online versions are an evolutionary relationship.
1. Background and status quo of intercommunication technology
The commercialization of IPv6 networks has played a key role in promoting IPv6 networks. Now, as an IPv4-dominated network. Many of us are still unclear about the IPv6 network address. Now let's take a look at the knowledge of IPv6 network addresses based on its installation problems.
JBoss7 configuration-Support for IPv4 and IPv6 Dual-stack Environments
Due to the needs of the lab project, the EJB 3.0 program is deployed in JBoss AS 7.1.1.Final, and IPv4 and IPv6 are required. However, the default configuration does not support IPv6. therefore, you can refer to the official JBoss Community Documentation document. In the 5.4.1 Interfaces and p
With the commercialization of IPv6, many home users have begun to use IPv6. However, the inherent existence of IPv4 makes many friends unfamiliar with the installation and configuration of IPv6, it is unclear about IPv6 installation and configuration for some Linux users. Now let's talk about how to install and configu
A new era came last month-"New Internet ". With the joint efforts of ISOC and manufacturers, the IPv6 protocol was officially started in June 6, which is called the "World IPv6 startup Day ". On this day, large enterprises such as ISP alliance and Google and Facebook started IPv6 forever. Although IPv6 Internet was not
Recently to start IPV6 equipment testing work, network deployment, the following host-related configuration also need to pay attention to, so record the relevant host to enable configuration IPv6 method (as to the principle and network device settings are not explained here)First, CentOS open IPv6Here is a static configuration example1, IPv4 static configuration of the original configuration[Email protected
