问题 Put another way, if an address is IPv4, why bother to express it as IPv6 at all? 回答1: It’s IPv4 expressed through IPv6 so that the application only needs to support one IP stack. Being able to reference IPv4 addresses through IPv6 notation means I can work on getting IPv6 support really solid in my application, and not have to worry about duplicating effort. These days some distributions disable IPv4 compatibility by default (e.g. Debian), and also Windows does this by default. To accommodate

AWS EC2 如何启用 IPv6

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 需要协同修改有四个地方,分别是 VPC 、Subnet、Security groups 和实例的网络设置,理论上只有第一个实例需要如此折腾,之后相同 VPC、Subnet 和 Security groups 的实例应当可以直接获取 IPv6 的地址 VPC 找到当前实例所属的 VPC 然后选择 Edit CIDRs: 然后点 Add IPv6 CIDR 就完事了: 新建的 VPC 直接选择 Amazon provided IPv6 CIDR block 就可以了: Subnet 同样的,找到当前实例所属的 Subnet 然后选择 Edit IPv6 CIDRs: 新建的 Subnet 直接输入想要的 IPv6 block 就可以了(一般从 00 开始,多个 Subnet 后续可以指定 01、02,诸如此类): Security groups 如果用户想要通过 IPv6 访问实例,还需要设置防火墙的相应规则,一般来说允许所有地址就是在 Inbound 的 Source 里设置 ::/0: 实例网络设置 进入当前实例的 Networking - Manage IP Addresses,然后选择 Assign new IP 即可: 最后在子网关联的路由表添加一条IPV6 至IGW的路由 测试 1

IPV6 国内进展情况

我是研究僧i 提交于 2019-12-27 09:31:18
国家下一代互联网产业技术创新战略联盟(以下简称“产业联盟”),近日在北京发布了我国首份IPv6业务用户体验监测报告(以下简称《报告》)。该《报告》监测了我国固定宽带的IPv6普及率,以及网站和移动应用软件对IPv6的支持率情况。   《报告》显示,我国固定宽带IPv6普及率为0.65%,IPv6覆盖用户数为240万户,IPv6活跃用户数为233万户;网站的IPv6支持率为7.59%,中央及省级政府、中央媒体及中央企业支持率为8.33%,其中国内排名前50名的网站支持率为4%,国内排名前50名的移动应用软件均不支持IPv6;移动宽带IPv6普及率为6.16%,IPv6覆盖用户数为7017万户,IPv6活跃用户数仅有718万户。   不难看出,尽管我国部署IPv6进展较快,但与国家规划部署的目标仍存较大差距,IPv6普及率有待提升。作为IP地址的第六版协议,IPv6是公认的下一代互联网商业应用解决方案。   对此,产业联盟常务副理事长傅承鹏介绍道:“IPv6能够为每个联网设备提供一个独立的IP地址,同时还有望解决端到端的连接、安全性、移动性等问题。随着万物互联时代的到来,IP地址短缺的问题日益凸显。部署IPv6有利于支撑大数据、 人工智能 等新兴技术的发展,提升我国互联网的承载能力和服务水平。”   此外,傅承鹏还认为当前影响我国IPv6部署的重要原因,在于网络改造对应用支撑能力不足

Google Recaptcha check timeout due to IPv6 issue - php on IIS

问题 My app is contentiously rejected by reviewers.They gives me below reason. Please revise your app and test it on a device while connected to an IPv6 network (all apps must support IPv6) to ensure it will launch without crashing. I've used objective-c and the api which I used is in php. Also I have used NSURLSession and NSURLConnection for calling the API's. I'm not using AFnetworking .I have done lots of RNDs from last two days. Can anyone suggest me how can I solve this issue? 回答1: If you are

问题 My hosting provider supports IPv6 for quite some time now. I am looking in to the possibility to migrate to Azure, but would like to know if IPv6 is supported on Azure. Is there any documentation available? 回答1: To quote the Azure faq: Microsoft has played a leading role in helping customers to smoothly transition from IPv4 to IPv6 for the past several years. To date, Microsoft has built IPv6 support into many of its products and solutions like Windows 8 and Windows Server 2012 R2. Microsoft

问题 I am having a strange problem which seems to be a problem of ipv6 vs ipv4 dns names. I have a real time scraper which runs on my server which runs on ipv6 network.
