How to support both IPv4 and IPv6 connections

阅读更多关于 How to support both IPv4 and IPv6 connections

问题 I'm currently working on a UDP socket application and I need to build in support so that IPV4 and IPV6 connections can send packets to a server. I was hoping that someone could help me out and point me in the right direction; the majority of the documentation that I found was not complete. It'd also be helpful if you could point out any differences between Winsock and BSD sockets. Thanks in advance! 回答1: The best approach is to create an IPv6 server socket that can also accept IPv4

Working with IPv6 Addresses in PHP

阅读更多关于 Working with IPv6 Addresses in PHP

After searching around somewhat thoroughly, I noticed a slight lack of functions in PHP for handling IPv6 . For my own personal satisfaction I created a few functions to help the transition. The IPv6ToLong() function is a temporary solution to that brought up here: How to store IPv6-compatible address in a relational database . It will split the IP in to two integers and return them in an array. /** * Convert an IPv4 address to IPv6 * * @param string IP Address in dot notation (192.168.1.100) * @return string IPv6 formatted address or false if invalid input */ function IPv4To6($Ip) { static

1.好象是由于dns解析慢的缘故 rmmod -f ipv6 去掉ipv6模块之后明显感觉到上网速度有提高。 vim /etc/modprobe.d/aliases 找到 #alias net-pf-10 ipv6 注释掉这句话。并update-module，重启就不会再加载ipv6模块了，用lsmod查看是否还有ipv6。 2.说是IPV6的问题，关闭就没事了。我还没试过，回家家试试看。办法是修改modprobe.conf： alias net-pf-10 off 还有一个老外说换了kernel2.6完全上不了网，原来是开了ecn，关闭此功能又可以了： echo 0 > /proc/sys/net/ipv4/tcp_ecn 转载于:https://www.cnblogs.com/beilon/archive/2008/05/30/1210428.html 来源： https://blog.csdn.net/weixin_30646505/article/details/99009401

API for configuring static IP addresses in an Android application

阅读更多关于 API for configuring static IP addresses in an Android application

问题 Is it possible to set the IP address of an interface in Android within an application? I can query the available interfaces and their current addresses using java.net.NetworkInterface , but this doesn't provide a facility to change these. Did I just miss something somewhere, or is it not allowed? I was hoping to be able to make my application either change or add an alias to one or more of the existing interfaces at runtime on an "off the shelf" device. (2.1/2.2). Ideally I'd like to do this

How to convert IPv6 from binary for storage in MySQL

阅读更多关于 How to convert IPv6 from binary for storage in MySQL

问题 I am trying to store IPv6 addresses in MySQL 5.0 in an efficient way. I have read the other questions related to this, such as this one. The author of that question eventually chose for two BIGINT fields. My searches have also turned up another often used mechanism: Using a DECIMAL(39,0) to store the IPv6 address. I have two questions about that. What are the advantages and disadvantages of using DECIMAL(39,0) over the other methods such as 2*BIGINT? How do I convert (in PHP) from the binary
