Network security protection under IPv6 scale deployment-IPv6 Security Technology question 7, ipv6 question 7
Due to the huge address space, IPv6 has a natural advantage in coping with some security attacks, network security is enhanced in terms of traceability, anti-hacker sniffing capabilities, neighbor discovery prot

2.2 The local site address has the following address format:
In hexadecimal notation: FEC0: X
The local site address is designed for internal addressing of sites that do not require a global prefix. The vro should not forward data outside the site to the local site or
Any package of the destination address
(Is it the same as the private address of class 192.168? )
For example, I am from CERNET and have a global unicast IPV6 address (in the case o
Ipv6,internet Protocol version 6, literally translated "Internet Protocol 6th Edition", is an IETF designed to replace the current version of the IP protocol-ipv4 protocol, known as "next-generation Internet Protocol". As early as June 6, 2012, the Internet Society organized the IPV6 agreement to launch the Conference. In June 2017, Apple made it clear that all developers would have to support
Take redhat9.0 as an example. The default kernel version of the system is 2.4.20-8, and the IPv6 module has been provided. The configuration process is as follows:
Log on as a root user (the commands in the following example are case sensitive)
Linux IPv6 Configuration 1: loading the IPv6 Module
Run the command insmod IPv6
What are the differences between IPv4 and IPv6? We can understand the difference between IPv4 and IPv6 through the following, we will appear IPv4 and IPv6 when we connect the wireless network, then where is the difference between the two? Want to know friend please see below.
Most of us use the second-generation Internet IPV4 technology, its biggest problem is t
IPv6 adoption: Challenges and Choices, and ipv6 adoption challenges
Today, many enterprises have begun to adopt IPv6 (Internet Protocol version 6th), and more countries are preparing to increase IPv6 traffic globally. As more and more devices connect to the Internet (such as smart cars, smart homes, and even smart cit
IPV6 is the abbreviation for Internet Protocol Version 6, where Internet Protocol is translated as "Internet Protocol". IPV6 is the next generation IP protocol designed to replace the current version of the IP Protocol (IPV4) by the IETF (Internet Engineering Task Force, Engineering task Force). The current version number for the IP protocol is 4 (IPV4), and its next version is
Currently, mainstream IP network applications use a 32-bit IP address (IPv4 ). Due to the unreasonable allocation of IP addresses and the rapid growth of the network, IP addresses have been exhausted. There are many solutions, such as NAT and VLSM. However, a more reasonable solution is to use IPv6 with a larger address space and provide solutions for IP network security and QoS. The sixth article in this series introduces ZXR10's
IPv6 address space
The most notable feature of IPv6 is its massive address space. IPv6 uses a 128-bit address length, which is four times the length of IPv4. When the address length is 32 bits, a maximum of 2 ^ 32 or 4,294,967,296 possible IP addresses are allowed. When the address length is 128 bits, there will be 2 ^ 128 or 340,282,366,920,938,463,463,374,607,4
IPV6 is the abbreviation for "Internet Protocol version 6", which is the next generation IP protocol designed by the IETF to replace the current version of the IP protocol-ipv4-.
At present we use second-generation Internet IPV4 technology, the core technology belongs to the United States. Its biggest problem is that the network address resources are limited, theoretically, IPV4 technology can use 4.3 billion of IP addresses, of which North America o

Many websites, such as Google, are both IPv4 and IPv6 Dual-line access. www.google.com resolution corresponds to many IP addresses, both IPv4 and IPv6. By default, the DNS server returns multiple IP addresses, while the local machine automatically selects the host based on the response speed of each address.
Generally, people will modify the hosts file in the system directory and specify the Google addre
