ipv6

这个树莓派配置是给我自己看的，有些关于fedora的配置 唯一要改的只有 resolv.conf(config nameserver)(DNS), wpa_supplicant(wifi passwd), ifcfg-“DeviceName”.conf(这是fedora的网卡配置文件名称) 配置/etc/resolv.conf domain 自己的hostname nameserver DNS DNS一般用114.114.114.114(电信)，8.8.8.8(谷歌)，或者校园网的在网络适配器那看看电脑的使用DNS 确定其他文件配好了，连上了网络，被网络分配了ip，却不能解析域名， 尝试是否能访问127.0.0.1(本机lo)，192.168.137.100(同一局域网内其他IP) 尝试是否能访问外网ip，和外网域名，能访问ip不能解析域名，是DNS没配置好，尝试删除resolv.conf文件，重启，树莓派开机自动网络配置时生成resolv.conf，会自己配置网中默认DNS IP和域名都不能访问，这可能是在访问外网出错，查看路由器，DNS，或者主机使用IP是否被禁。 ping 127.0.0.1 ping 192.138.137.100 ping 114.114.114.114 ping 14.215.177.39 #百度主页ip ping www.baidu.com 查看

I am going to publish an app on Apple Store then I came to know about IPV6 rejection issue. My app only support for IPV4 and on this link I found that app should support IPV6. So my question is that, Is it compulsory that app must support for both IPV4 & IPV6? Sorry if looks as a foolish question but I am looking for a Apple link & more detail before getting rejected from Apple. You don't need to worry about IPv6 support, if you've not set hard-core IPv4 IP address in your web server/service url connection. This Apple document will help you: Supporting IPv6-only Networks All apps submitted to

I can't seem to find out why this regular expression is not working in PL/SQL . if ( REGEXP_LIKE(v,'/^(?>(?>([a-f0-9]{1,4})(?>:(?1)){7}|(?!(?:.*[a-f0-9](?>:|$)){8,})((?1)(?>:(?1)){0,6})?::(?2)?)|(?>(?>(?1)(?>:(?1)){5}:|(?!(?:.*[a-f0-9]:){6,})(?3)?::(?>((?1)(?>:(?1)){0,4}):)?)?(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[1-9]?[0-9])(?>\.(?4)){3}))$/iD') ) then It's for validating IPv4 and IPv6, it came from here: https://stackoverflow.com/a/1934546/3112803 Not sure if this has anything to do with it but I also asked this question about the D flag on the end: What Does This Regular Expression (RegEx) Flag

Closed . This question is opinion-based . It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post . Closed last year . My last release of application which is 12.8 is rejected by apple saying that i have to add the IPv6 support to the app, I read and reviewed the recommended apple doc named Supporting IPv6 DNS64/NAT64 Networks thoroughly and came to know that already i am using the NSURLConnection class for network connectivity which is mentioned in the same doc, you can see the image from doc

I've been working on generating a CIDR from ranges of IPv4 and IPv6 addresses using T-SQL running on a SQL Server 2012 instance. Generally our application (outside of the db) is responsible for calculating a CIDR, but I presently have need to do the CIDR calculation in the database. Because IPv6 is too large to store in the bigint datatype we store IP addresses as either binary(4) or binary(16) . Calculating the route prefix for an IPv4 range is relatively simple if a little ugly: declare @ipv4_begin binary(4) ,@ipv4_end binary(4) set @ipv4_begin = 0xC0A80000 -- '192.168.000.000' set @ipv4_end

一、IPv6和IPv4都属于“互联网协议”。 二、IPV6与IPV4的区别： 1、IPv6的地址空间更大。 （1）IPv4中规定IP地址长度为32，即有2^32-1个地址。 （2）IPv6中IP地址的长度为128,即有2^128-1个地址。 2、IPv6的路由表更小。 （1）可使路由器能在路由表中，用一条记录表示一片子网。 （2）大大减小了路由器中路由表的长度，提高了路由器转发数据包的速度。 3、IPv6的组播支持以及对流的支持增强。 这使得网络上的多媒体应用有了长足发展的机会，为服务质量控制提供了良好的网络平台。 4、IPv6加入了对自动配置的支持。 5、IPv6具有更高的安全性。 在使用IPv6网络中，用户可以对网络层的数据进行加密并对IP报文进行校验，这极大地增强了网络安全。 6、IPv6允许协议扩充。 7、IPv6使用新的头部格式，简化和加速了路由选择过程，因为大多数的选项不需要由路由选择。 好文要顶 关注我 收藏该文 二、IPV6与IPV4的区别： 1、IPv6的地址空间更大。 （1）IPv4中规定IP地址长度为32，即有2^32-1个地址。 （2）IPv6中IP地址的长度为128,即有2^128-1个地址。 2、IPv6的路由表更小。 （1）可使路由器能在路由表中，用一条记录表示一片子网。 （2）大大减小了路由器中路由表的长度，提高了路由器转发数据包的速度。 3

地址空间不同，IPv4中规定IP地址长度为32，而IPv6中IP地址的长度为128。 路由表大小不同，IPv6的路由表相比IPv4的更小。 IPv6的组播支持以及对流的支持要强于IPv4。 安全性不同，IPv6的安全性更高，在使用IPv6的网络时，用户可对网络层的数据进行加密。 协议扩充不同，IPv6允许协议进行扩充而IPv4不允许。 来源： https://www.cnblogs.com/czydbk/p/11957229.html

I'm trying to port an ipv4 server/client to ipv6, but the compiler says SOCKADDR_IN6 is not declared in the scope. SOCKADDR_IN is declared but not SOCKADDR_IN6 . <Winsock2.h> is included. Any one have any ideas why it would be undeclared? Microsoft's documentation for sockaddr_in6 says that it is defined in the ws2tcpip.h header, probably you need to include that. On Linux you'd need different includes, sys/socket.h and netinet/in.h . I have currently found SOCKADDR_IN6 definition in ws2ipdef.h header (Visual Studio 2008). However, as said in a comment below, MS Docs states that this header

I would like to use WMI (in C++) to configure a static IPv6 address. Configuring a static IPv4 address is working fine using EnableStatic , which is part of a WMI class named Win32_NetworkAdapterConfiguration . Can anyone help me configure an IPv6 address using WMI? I have been looking for example code, but have not found any. No. According to the Win32_NetworkAdapterConfiguration documentation on the MSDN web site , this API supports limited IPv6 functionality (looks like it's limited to just reading addresses on an interface) starting in Windows Vista.
