ipv6虚拟主机是做什么的？ IPv6虚拟主机就是支持IPv6网络访问的虚拟主机产品。可避免ipv6网络用户访问障碍的问题。 目前，市面上可提供支持IPv6虚拟主机的商家非常少，大部分都是ipv6改造升级服务。 现在很多IDC都推出了支持ipv6访问的双栈虚拟主机，双栈虚拟主机支持IPv4+IPv6双栈协议。 ipv6是下一代网络基础技术协议，随着ipv4地址的正式耗尽，IPv6可缓解全球IPv4地址资源枯竭现状，支撑5G、物联网时代的网络建设需求。 购买双栈虚拟主机后，无需专业技术部署，即买即用，可避免网站客户因IP协议不同而无法访问的问题。能同时和IPv4网络&IPv6网络通信。 idc双栈虚拟主机提供4种不同的配置类型，价格也不同，且配有数据库，额外赠送域名和企业邮箱，可满足不同用户的网络需求。 除了ipv6虚拟主机，云服务器用户新开电信机房也可全面支持IPv6，除免费分配一个IPv4公网地址外，还赠送32个IPv6地址，实现v4/v6双栈支持。 智简魔方 数据中心基础设备管理系统（DCIM） 面向IDC设计，提供从机房机柜、交换路由、到物理服务器、IP资源、自动重装、自动管控等一系列功能的IDC基础资源管控软件，最终实现IDC资源交付管控的全面自动化。 来源： 51CTO 作者： wx5ddf603380b46 链接： https://blog.51cto.com

Use of IN6ADDR_SETV4MAPPED and dual stack sockets

由 大兔子大兔子 提交于 2019-12-09 13:46:20
问题 This is a continuation of Connecting IPv4 client to IPv6 server: connection refused. I am experimenting with dual stack sockets and trying to understand what setsockopt with IPV6_V6ONLY is useful for. On the linked question I was advised that "Setting IPV6_V6ONLY to 0 can be useful if you also bind the server to an IPv6-mapped IPv4 address". I have done this below, and was expecting my server to be able to accept connections from both an IPv6 and an IPv4 client. But shockingly when I run my

expand ipv6 address in shell script

I'd like to update a djbdns (dbndns) configuration file based on a given IPv6 address, e.g. 2a01:488:66:1000:523:f116:0:1 or ::1 . dbndns requires expanded IPv6 addresses, e.g. 2a010488006610000523f11600000001 for 2a01:488:66:1000:523:f116:0:1 . What's the most simple way to expand such an IPv6 address? Using sipcalc might do it. It gives more information than you need, but a bit of grep and cut can solve that :-) $ EXPANDED=`sipcalc 2001::1 | fgrep Expanded | cut -d '-' -f 2` $ echo $EXPAND 2001:0000:0000:0000:0000:0000:0000:0001 For reference, this is the full output of sipcalc : $ sipcalc

Since IPv6 is going to replace IPv4, should I develop my new application to support it?

由 被刻印的时光 ゝ 提交于 2019-12-09 06:48:01
问题 I develop applications using many languages and a few platforms. From what I am reading, IPv6 is going to be mainstream within then next 5–10 years, and that some ISPs even offer direct connection to the IPv6 Internet. On my private network, all the machines have dual stack connectivity and communicate with each other using IPv6 when possible. My question is: should my new application be written to support IPv6? If so, what are the things I need to consider? Are there any downsides to

Why is my server slow and SSL mismatching when combining IPv4 with IPv6

由 喜夏-厌秋 提交于 2019-12-08 16:00:19
问题 I'm setting up a new server with Ubuntu 18.04.1 Nginx 1.14.0 with HTTP2 and PHP 7.2.7 This is the first server that I try to setup with both IPv4 and IPv6 enabled. Everything works fine until I tested a page with a lot of missing images. It seems to take forever for the server to realise they are missing and respond to the http request. Some missing files give a HTTP status of "502 bad gateway". Is it a DNS problem that causes these delays and 502 errors and what should I change in the setup?

How to make API calls IPV6 compatible in react-native using the .fetch function?

由 本小妞迷上赌 提交于 2019-12-08 15:53:42
问题 I have developed an app (for IOS) written in react native which is working good in IPV4 networks. However, recently Apple has sent a message saying that my app did not work when tested in an IPV6 network. They told me that I had to make it compatible with IPV6-only networks too. The question is, how can I make my existing API calls compatible with an IPV6 network? My API uses the https protocol and it is called by domain name, not a raw IP. A sample fetch call that I use is: fetch(query,{

What are the primary differences between IPv4 and IPv6? [closed]

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago . I understand that the pool of IP addresses has been increased (32bit to 128bit). Are there some other primary differences between the two? 回答1: IPv4 uses a 32-bit address scheme, allowing for 2^32 different addresses. IPv6 uses a 128-bit address scheme, allowing for 2^128 different addresses. The biggest

Get all IPv6 addresses on all interfaces (Windows)

由 你说的曾经没有我的故事 提交于 2019-12-08 13:11:35
问题 I have a solution using WMI, unfortunately only on Windows Vista and above. On WinXP/2003 WMI will only return IPv4 adresses. Is there any way to get all assigned addresses including IPv6 ones on WinXP? Adt: No .NET, just WMI or WinAPI please. 回答1: Well, after some more hours of googling, I finally found GetAdaptersAddresses() in the MSDN library. Sometimes you just use the wrong search terms it seems. 来源： https://stackoverflow.com/questions/3214653/get-all-ipv6-addresses-on-all-interfaces
