ipv6

问题 I am new to swift and xcode & have had my app rejected due to IPV6: Performance - 2.1 Your app crashes on an iPad and an iPhone running iOS 9.3.5 connected >to an IPv6 network when we: Specifically, when we touch the More button in the bottom right hand corner of the app it crashed. I have spent a lot of the day doing reading around ipv6 and have concluded that it may be the reachability class I am using. I have a couple of questions, how would I modify the code to include ipv6: public class

问题 With IPv4 I can bind() to a specific address to select the interface that will be used to receive the packets (and in some case, also to send, but that's not the point). On a dual stack IPv6/IPV4 machine I have this problem: I can create a 6 socket and use it to receive 4 traffic, but if I want to bind to a specific interface, I have to choose an IP address to bind to. If I bind to an IPv6 address, I'll filter out all the IPv4 traffic and vice versa. How can I receive both IPv4 and IPv6

问题 Is it possible to have a Socket that listens and accepts both IPv6 and IPv4 clients? I used a IPv6 socket in C# hoping that it would automatically be backwards compatible but IPv4 clients cause an invalid ip address exception. 回答1: Have a look here. You can accept IPv4 clients as well as IPv6 clients with the one server socket. 回答2: Set the socket's IPv6Only option to false : Socket MySocket = new Socket(AddressFamily.InterNetworkV6, SocketType.Stream, ProtocolType.Tcp); MySocket

问题 In a web project . I see the log: hadoop.hbase.zookeeper.ZKConfig - java.net.UnknownHostException: example.com at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method) at java.net.InetAddress$1.lookupAllHostAddr(InetAddress.java:850) at java.net.InetAddress.getAddressFromNameService(InetAddress.java:1201) at java.net.InetAddress.getAllByName0(InetAddress.java:1154) at java.net.InetAddress.getAllByName(InetAddress.java:1084) at java.net.InetAddress.getAllByName(InetAddress.java:1020) at

问题 If IPv4 is in question and I want to extract IP and ICMP header out of std::istream, first I get the initial 20 bytes, then check if the header lenght provided in the IPv4 header is larger than 20 bytes in order to extract any options. The next bytes are the ICMP packet. Using the header lenght value carried inside the IPv4 header I can see the expect size of the IP header. However how to get the exact size of IPv6 header? There is a payload value inside IPv6 header that includes the size of

问题 Just as we have rules governing the validity of an IPv4 netmask, does IPv6 have its own set of rules to qualify a netmask? Thanks! 回答1: What is your use case? Normally in IPv6 your addresses will be auto-generated from a /64 prefix your router provides. You don't usually see a netmask written out in IPv6. Usually you will see a prefix length. For example: 2001:db8:0:160::/64 would have a netmask of ffff:ffff:ffff:ffff:: But you would only ever see the former. 回答2: Technically the better

问题 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. 回答1: You don't need to worry about IPv6 support, if you've not set hard-core IPv4 IP address in your web server

问题 If we use a 32-bit integer to store an IPv4 address, then the byte order of the integer must be considered. However, as there is no built-in 128-bit integer type under almost all platforms, an IPv6 address must be stored into a byte array, so, I think the byte order is no longer a problem. Am I correct? Or is there a corresponding function htonlXXX for IPv6? 回答1: IPv6 does require network byte order for ipv6 addresses. hton and ntoh are all about converting the address from how you have it
