The use of the IPv6 network protocol is nothing new, but many people do not know about the network protocol and its features. We will help you introduce some of its features in detail today. First, let's take a look at its biggest feature-address space. (1) huge address space The source and target addresses of IPv6 are both 128-bit (16 bytes) and can provide IP addresses almost unrestricted. 128-bit can exp

Still using IPv4? Still not installing IPv6? You are too OUT. Follow this article to install IPv6. A detailed text description is provided. Make sure everyone can learn. Not much nonsense. I. precautions before installing the IPv6 protocol 1. It is recommended that your computer be directly connected to the port on the campus network.

1, what is IPV6? This problem can go to Baidu or Google find, there should be a great harvest, in fact, is mainly to solve the problem of IPV4 address, V4 address is 32, that is: 192.168.1.1, and V6 address is 128, than the V4 enlarged too many times. 2, IPV6 have subnet mask? It can be said that there is, it can be said that there is, because there is a prefix in the

With the gradual promotion of IPv6, the information center of our company is just preparing to study the construction of wireless network. Due to the limited funds, I bought a TL-WR841N wireless router and 2 TL-WN821N 11N wireless usb Nic for testing. However, the central office still needs to use IPv6 networks frequently to manage and maintain servers in IPv6 ne

Due to the design defect of the IPv6 protocol, it cannot be compatible with IPv4, which makes the current phase unable to achieve overall migration to the IPv6 network. It is reported that IANA, The Global IPv4 Address Allocation Management Organization, released the last remaining IPv4 address at the beginning of this year. That is to say, the global IPv4 address has been allocated, so

(This case uses two cisco2500 routers, IOS (tm) 2500 Software (C2500-IS-L), Version 12.2 (15) T9, the interconnection between two remote ipv6 subnets can be achieved by using the ipv6 v4 trunk and ipv6 6to4 tunnel combined with ipv6 Static Routing. Topology Description: Use the e0 interface of the two routers to inter

When IPv6 is widely used, the Mobile IPv6 protocol for communication is not weak. Therefore, understanding of the Mobile IPv6 protocol is essential. Now let's discuss the related issues. The Mobile IPv6 node uses the Internet to control the Message Protocol (ICMP) router to search for messages to determine its location

In traditional IPv4 networks, security has always been a headache. Now the IPv6 protocol network has solved many security problems for us. This is because, in the IPv4 network, the evolved version V6 adopts different transmission structures, so the security mechanism has changed. But is this really safe? The IP Security Protocol (IPSec) IPSec is an optional extension protocol for IPv4, while the IPv6 protoc

Today, I saw an exciting message on the Google App Engine blog: "Today, we're adding the same service (Google over IPv6) to all domains hosted by ghs.google.com ." What does this mean? You should have thought about it. Especially the miserable blogger in mainland China. The new GHS cname domain name deployed by Google is ghs46.google.com. In view of the IPv6 support provided by Windows Vista and Windo

1. IPV6 basic configuration 650) this. width = 650; "onclick = 'window. open (" http://blog.51cto.com/viewpic.php? Refimg = "+ this. src) 'onclick =" window. open ("http://blog.51cto.com/viewpic.php?

Through the previous article, we should have an understanding of IPv6 protocol addresses. We are now giving a further explanation of this issue. Many of my friends have many questions about this 128-bit address algorithm. We have two answers to these questions to see if you can find the answers you need. The IPv6 Protocol address is 128 bits. Does it take a lot of time to configure the address?

We have already talked about the dual-stack protocol and tunnel protocol in our discussion of the networking proposal for coexistence of two networks. This is also the mainstream strategy. Next, let's introduce Translation Strategies to you. There may be fewer people who know about them. Here, we will focus on the translation policies related to the IPv6 protocol stack. Translation Strategy During the network transition period, it is impossible for al

Although IPv6 headers have two times the length of 40 bytes and 20 bytes), IPv6 has a simplified header structure. The IPv6 Header has eight fields, while IPv4 has 14 fields. IPv6 discards and uses several IPv4 header fields to make packet processing more efficient.The following two headers are compared. The Version fi

Three configuration methods for IPv6 in Linux: 1. automatically obtain the IPV6 address, modify the/etc/sysconfig/network file, add the following configuration text NETWORKING_IPV6 = yes, and then, run the Command service network restart and run the command ifconfig-a to view IPV6 address information: 2013-10-182, static IPV6
