Technical Features of IPv63.1 What are the significant advantages of IPv6 over IPv4?
Compared with IPv4, IPv6 has the following significant advantages:
1) The address capacity is greatly expanded from the original 32-bit to 128-bit, which completely solves the problem of IPv4 address insufficiency. the hierarchical address structure is supported to facilitate addressing; extended support for multicast and a
1. What isIPv6 IPV6 refers to the Internet Protocol (IP) version 6th. At present, we mainly use Internet Protocol Fourth edition, namely IPv4. With the global Internet highly developed today, IPV4 address resources have dried up and the internet is undergoing a transition from IPV4 network to IPV6 network. The IPV4 address is similar to the A.B.C.D format, with a total of 32 bits. Divided into four segments

A summary of methods to disable IPV6 under Linux--http://www.jb51.net/linuxjishu/335724.htmlThis article mainly introduces the method of disabling IPv6 in Linux, the operation of disabling IPV6 or considering the current and IPV4 compatibility issues, the need for friends can refer to the followingPV6 is considered an alternative to the traditional 32-bit address
Everything has two sides, and there is always one disadvantage if there is a benefit. Just like IPv6, it brings almost unlimited IP Address resources to the Internet, but also changes the security environment of the Internet, bringing greater risks to it.
According to the information of some network attack events, although the transition from IPv4 to IPv6 has just begun, Some attackers have begun to spread

You can postpone the deployment of the IPV6 strategy as you wish, but you must immediately address the security implications of IPV6. If you plan to IPv6 and IPV4 on a dual stack configuration, then you can't take it lightly in terms of security. If you think about turning your whole IPv6, it doesn't mean you can sit s
Network Layer 2 (IPv4 and IPv6 addresses and related protocols) IP (internet protocol) protocol is the core protocol of the TCP/IP protocol family and the network layer of the internet.
