Technorati labels: IPv6, IPv6 ACL
In fact, IPv6 ACL (access-list) is similar to IPv4. It should be used as an exercise to verify the principle.
1,Standard access list.

IPV6 is what we commonly call Internet Protocol, is the core protocol of TCP/IP, then how to open IPv6 under Linux? The following is an example of Ubuntu, to introduce you to Ubuntu enable IPv6 method.Method:$sudo Apt-get Install Miredo$ifconfigA virtual network card called Teredo should be visible in the results.$ ping6 ipv6
We are not unfamiliar with the technology of tunneling, and apply it to the interworking between IPv4 and IPv6. Tunneling technology has played an important role in this transitional technology, so let's take a look at some of the relevant terminology and standards for interoperability.
What are the common technical standards for IPV4 and IPV6 interchange conversion at present?
The transition from existin
In the past few years, IPv6 has gradually become the mainstream, but many IT professionals are still helpless when facing IPv6. Indeed, IPv6 and IPv4 are quite different, this article is intended to help you eliminate IPv6 phobia.
1. The IPv6 address is a 128-bit hexadecimal
First, IntroductionLet's assume that the hosts discussed in this chapter support dual stacks, that is, support for IPV4 addresses, and Ipv6 addresses.We are talking about the point: the client and server side use different types of addresses. Because the same type of address has nothing to say.Second, IPV4 client and IPV6 serverThat is, the client uses the IPV4 address socket to communicate, and the server
The popularization of IPv6 protocol is only a matter of time, because in the current network status, the existing problems have made it imperative for us to change protocol standards. What are the characteristics of IPv6? Next we will summarize the eight features of IPv6. I hope it will be useful to you.(1) huge address spaceThe source and target addresses of
RHEL 7 CentOS 7 To disable the IPV6 method and the previous version is not the same, this article sorted out the processing method: The source of this article: http://blog.csdn.net/bluishglc/article/details/ 41390785 prohibit any form of reprint, otherwise will entrust CSDN official safeguard rights and interests.
First, we have to give the most fundamental solution: modify grub to not load the IPV6 modul
The tunnel technology is used to connect the two networks that are currently used by both protocols, that is, the IPv6 network and IPv4 network, to ensure compatibility. Now let's mainly analyze this technology.
Tunneling Technology
In the early stages of IPv6 development, there must be many local pure IPv6 networks, which are isolated by IPv4 backbone networks.
In the network, IP addresses are the foundation, so the packet header format is also very important. Although the format of IPv6 headers has been standardized A long time ago, IPv6 is gradually put into use. Let's talk about the structure of IPv6 headers.
IPv6 Header Format
IPv6
Web technology drives the Internet to develop at an alarming rate. 10 years ago, people who were concerned about the future expansion of the Internet began to worry that the limitations of the IPV4 network would be difficult to support the sustainable development of the Internet. To this end, the IETF launched a new generation of Internet Protocol--ipv6. Compared with IPV4, IPV6 offers a number of new featu
The two major problems facing internet basic technology IPv4 are address resource depletion and backbone router route table explosion. These two problems are the defects of IPv4 protocol, only a large modification can be done. After years of discussion and comparison and trade-offs of various solutions, the next-generation IP protocol has been basically developed and assigned version 6, called IPv6.One of the key problems facing
Now we have gradually entered the IPv6 Protocol use environment. However, many people are not familiar with this emerging standard. Especially for the installation of IPv6, there are endless problems. Now we will introduce the standard installation process in detail.
I. precautions before installing the IPv6 protocol
1. It is recommended that your computer be dir
With the advancement of IPv6, we also have corresponding hardware products in China. IPv6 core routing is one of our important technologies. Now let's take a look at the content in this regard. What are the characteristics of the IPv6 core path that plays an important role in network construction?
CNGI-CERNET2 proposed and determined the "using domestic
In the network overuse phase, we will use the dual-stack technology to connect the two networks. In the double stack technology, IPv6 multicast provides powerful functions. It can run on both the router and host, and can write v4 and v6 to form a convergence point. In transition technology, IPv6 multicast is very important. We will discuss this in depth.
IPv6 mul
IPv6 has not been fully popularized yet, but IPv6 is effective after the system is installed, which affects network performance to a certain extent. Therefore, we recommend that you disable IPv6. Now we will describe how to disable it in the complete steps in this article. 1. Modify/etc/sysconfig/network and change the second line to no: NETWORKING = yesNETWORKIN
has developed the Next Generation Internet Protocol IPv6. IPv6 inherits many features of IPv4, and its huge address space can meet the rapid development of the Internet. It also integrates content such as mobility, security, and service quality. Therefore, IPv6 Protocol [2] is urgently needed on the mobile Internet.
Ii. Mobile
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
Modify the/etc/sysconfig/network corresponding network card, append:
The code is as follows
Copy Code
Networking_ipv6=no
2. Modify the/etc/hosts, the IPv6 of the local host name resolution also commented out:
The code is as follows
Copy Code
#::1 localhost Localhost6 localhost6.localdomain6
3. Create file/etc/modprobe.d/ipv6off.conf (name casually)
Note: There is no/etc/mod
