Quick way of expanding IPv6 Addresses with PHP

由 谁都会走 提交于 2019-12-17 19:01:52
问题 I was working on a project where I needed to expand IPv6 addresses. There are not many functions out there created by other users, and the ones that exist are ugly. Some of them included multiple foreach 's and gmp_init , which added a lot of overhead and harder to maintain code. I need a simple, non-taxing script to expand IPv6. Posting this for the community. 回答1: The following is a two liner, where $ip is a condensed IPv6 address. Returns expanded $ip . Example : $ip = "fe80:01::af0"; echo

PHP5 calculate IPv6 range from cidr prefix?

由 孤人 提交于 2019-12-17 16:58:34
问题 I am able to do this with IPv4 using code snippets from various online sources. I was wondering if there was a way to do it with IPv6. Basically I just need a form that I can enter an IPv6 address and prefix (ex: address/68) and it calculates the network address, first useable address, last useable address, and broadcast address. Then just prints to screen. Not looking to store it in a database or anything yet. How would I go about doing this? Thanks to everyone in advance! 回答1: First of all:

IPV6之负载均衡SLB初尝试

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 背景信息： IPv6是Internet Protocol Version 6的缩写，其中Internet Protocol译为“互联网协议”。IPv6是IETF（互联网工程任务组，Internet Engineering Task Force）设计的用于替代现行版本IP协议（IPv4）的下一代IP协议，通过将IPv4中32位的地址长度扩展为128位，使得地址空间扩大了79,228,162,514,264,337,593,543,950,336倍。使用IPv6，可以让全世界的每一粒沙子都能分配到一个IP地址。 准备材料： 两台WEB服务器，一个域名，一个已开通IPV6的负载均衡SLB 实战初尝试一： 1.创建IPv6负载均衡实例（ 传输门 ） 2.查看已创建的负载均衡SLB实例 3.添加后端服务器（确定已搭建了WEB服务） 4.为负载均衡SLB添加监听 5.检查负载均衡监听状态 6.登陆域名解析控制台（做一个AAAA的解析，解析的记录值为负载均衡的IP地址） 7.使用第三方IPv6测试网，进行检测，（ 点我进入传送门 ） 来源： oschina 链接： https://my.oschina.net/u/3611008/blog/1830960

PHP $_SERVER['REMOTE_ADDR'] shows IPv6

由 被刻印的时光 ゝ 提交于 2019-12-17 16:28:40
问题 I am facing an issue with $_SERVER['REMOTE_ADDR'] in PHP It is giving a IPv6 like value even though the server is using IPv4. Can anyone help me to resolve this issue. 回答1: The server is then accepting connections on an IPv6 socket. Some operating systems can do both IPv4 and IPv6 on an IPv6 socket. When that happens the IPv6 address will look like ::ffff:192.0.2.123 or ::ffff:c000:027b which is the same address but written in hexadecimal. If you see IPv6 addresses like 2a00:8640:1::224:36ff

问题 Yesterday, I submitted my app for review, but I got this message from Apple: We discovered one or more bugs in your app when reviewed on iPad iPhone running iOS 9.3.2 on Wi-Fi connected to an IPv6 network. Specifically, upon review we have found the application still experiences a loading issue and unable to review the application content. My app uses ionic framework, how can I fix this problem? I already used domain to access my server, but this problem still exists. 回答1: Yes. According to

IIS Request.UserHostAddress returning IPV6 (::1), even when IPV6 disabled

由 时间秒杀一切 提交于 2019-12-17 10:53:25
问题 In the properties section of my network card, on windows server 2008, i have IPV6 disabled, leaving only IPV4 enabled. However in ASP.NET, Request.UserHostAddress returns '::1', an IPV6 address. Has anyone got any idea how to revert back to IPV4? 回答1: If you're connecting to localhost (::1 / 127.0.0.1), you're not using the network card that your server has, but rather like a virtual card that windows has. I don't think there is anyway to configure the loopback card and removing IPv6 from it,

How can I disable IPv6 stack use for IPv4 IPs on JRE?

问题 As you can see on below screenshots, eclipse and Android SDK Manager (and other Java programs) are trying to connect to a IPv4 Internet IP via IPv6 TCP/IP stack while Proxifier (a proxy manager program, nevermind) can not support that. How I can disable IPv6 in Java? 回答1: I wanted to use this for some program I hadn't control for running that Java app so ended with this _JAVA_OPTIONS=-Djava.net.preferIPv4Stack=true environment variable.

How can I convert IPV6 address to IPV4 address?

由 你离开我真会死。 提交于 2019-12-17 06:55:43
问题 I have application that uses IPv4 addresses (it stores them as long), so it only understands IPv4 addresses. Is it possible to convert IPv6 address to IPv4 with Java ? 回答1: While there are IPv6 equivalents for the IPv4 address range, you can't convert all IPv6 addresses to IPv4 - there are more IPv6 addresses than there are IPv4 addresses. The only sane way around this issue is to update your application to be able to understand and store IPv6 addresses. 回答2: The IPAddress Java library can
