IPv4 和 IPv6 是两种不同的网络协议,如果你的计算机仅配置了 IPv4 或仅配置了 IPv6,那么它们之间的通信将会遇到问题,因为这两个协议并不兼容。这意味着如果你在网络中有一台设备仅支持 IPv4,而另一台设备仅支持 IPv6,它们之间无法直接通信。为了解决这个问题,可以考虑以下几种方法: ...
第一个问题是由于IPv4 地址耗尽问题,无状态IPv4/IPv6 翻译必须能够复用公有IPv4 地址以高效使用IPv4 地址资源;第二个问题是目前有的应用程序并没有IPv6 的版本(如Skype" style="color: rgb(51, 51, 51); margin: 0px; padding: 0px; line-height: 20px; text-decoration: none; border-bottom-width: 1...
Your device uses either a static IP or a dynamic IP addressing system when you connect to the internet. With static IP addresses, you essentially use the same address every time you connect to the internet. However, dynamic IP addresses are temporary and assigned every time a device connects ...
本文翻译自Internet Society的文章,Frequently Asked Questions (FAQ) on IPv6 adoption and IPv4 exhaustion,对原文感兴趣可查看英文原文。 已经有好几个组织号召部署新版互联网协议IPv6,旨在最终代替IPv4协议。互联网安全协会强烈支持这种号召。实际上,由互联网协会在2012年6月6日主导的“World IPv6 Launch”是IPv6...
IPv6 increases the IP address size from 32 bits to 128 bits, to support more levels of addressing hierarchy, a much greater number of addressable nodes, and simpler auto-configuration of addresses. The scalability of multicast routing is improved by adding a "scope" field to multicast addresses...

IPv4 vs IPv6 Impact of IPv6 Deployment on Existing Networks and Services Why Do We Need IPv6? Internet Protocol (IP) is a network layer protocol in the TCP/IP protocol suite. (The network layer protocol is mainly responsible for addressing in the Internet, guiding the data packet to the ...
无状态双重IPv4/IPv6翻译模式(MAP-T)的应用场景如图3所示。 图3 无状态双重IPv4/IPv6翻译模式的应用场景 图3中,核心翻译器称为BR,对于IPv6为路由器,对于IPv4为可以复用IPv4地址的IPv4/IPv6翻译器。第二次翻译在家庭网关CE上进行,CE对于IPv6为路由器,对于IPv4为IPv4/IPv6翻译器,并且根据下述端口映射算法对于传...
IPv4 vs. IPV6 The advent of IPv6 brought more functionality, in addition to more IP addresses. For example, IPv6 supports multicast addressing, which allows bandwidth-intensive packet flows (such as multimedia streams) to be sent to multiple destinations simultaneously, reducing network bandwidth. ...
Here are some reasons why the world is transitioning from IPv4 to IPv6: 1. Exhaustion of IPv4 addresses IPv4 uses 32-bit addressing, which can only accommodate up to 4.3 billion unique IP addresses.With the growth of the internet and the proliferation of connected devices, this finite pool ...
