Apps are reviewed on an IPv6 network. Please ensure that your app supports IPv6 networks, as IPv6 compatibility is required

问题 I have received the following rejection from Apple for my app the last couple of days. My app communicates with UDP and the remote server is always IPv4. I have used BSD sockets. Please guide me how can I solve this problem. I have tried to create a NAT64 hotspot using an IPv4 network but I was unable to send any packets to the server. Moreover, we don't have IPv6 available at my place now. From Apple: 2.2 Details We discovered one or more bugs in your app when reviewed on an iPad running iOS

Both Dns.GetHostAddress and Dns.GetHostEntry return only ipv4 address. How do I get both ipv4 and ipv6 addresses?

问题 A simlar question has been asked here and here and here but none of the answers seem to work so I'm posting actual code and showing it running on an ipv6 capable machine hoping someone can suggest a solution Here's the code taken from both questions using System; public class HelloWorld { static public void Main () { string hostName = "google.com"; // uri.DnsSafeHost; Console.WriteLine("DNS.GetHostAddresses: " + hostName); var hostAddresses = System.Net.Dns.GetHostAddresses(hostName); Console

IPv6 support for Azure other than the load balancer thing

由 非 Y 不嫁゛ 提交于 2019-12-08 09:33:42
问题 I have two questions regarding azure and IPv6. I understand that you can assign private IPv6s to VMs and then connect them to a load balance with a public IPv6, but is there anyway to use IPv6 with other resources in Azure, such as, cloud services, virtual networks, Application gateway, NSG, VPN Gateway, App Services, SQL databases, and SQL DWH? Also, I see that it says you cannot upgrade VMs to IPv6 and you need to make new ones. Does that mean that you would only have to remake VMs that

Python: ipaddress AttributeError: 'str' object has no attribute

Following the advice given here , I'm using the check the ipaddress module to perform checks of type: In [25]: IPv4Address(u'100.64.1.1') in IPv4Network(u'100.64.0.0/10') Out[25]: True Works fine in IPython. Yet when I turn it into a function: import ipaddress def isPrivateIp(ip): ip4addressBlocks = [u'0.0.0.0/8', u'10.0.0.0/8', u'100.64.0.0/10', u'127.0.0.0/8', u'169.254.0.0/16', u'172.16.0.0/12', u'192.0.0.0/24', u'192.0.2.0/24', u'192.88.99.0/24', u'192.168.0.0/16', u'198.18.0.0/15', u'198.51.100.0/24', u'203.0.113.0/24', u'224.0.0.0/4', u'240.0.0.0/4', u'255.255.255.255/32'] unicoded =

iOS - Get device's DNS server address on IPv6 only network

问题 I am trying to get device's DNS server address while connected to IPv6 only network on iOS. The following code works well for when connected to IPv4 network but doesn't work on IPv6 network. Code taken from this answer. res_ninit(&_res); res_state res = &_res; for (int i=0; i < res->nscount; i++) { sa_family_t family = res->nsaddr_list[i].sin_family; if (family == AF_INET) { NSLog(@"IPv4"); char str[INET_ADDRSTRLEN]; // String representation of address inet_ntop(AF_INET, & (res->nsaddr_list[i

storing/retrieving IPv4 & IPv6 addresses in MySQL

由 梦想的初衷 提交于 2019-12-08 07:51:35
问题 Sorry I don't know much about this subject, but all I'm looking for is a quick-and-easy solution for uniquely representing any IP address (v4/v6) in MySQL so I can easily retrieve the last time (if any) that a particular computer has visited my site. I don't need to do any computations on the addresses, just retrieval, so any unique representation should be ok. I do plan on storing a lot of these (don't have an estimate yet), so space may become a concern. I've seen many solutions for storing

Domain name to IPv6 address in Perl

由 我与影子孤独终老i 提交于 2019-12-08 07:39:32
问题 I have the following Perl code to translate domain name to IP address. It works fine in IPv4. $host = "example.com"; $ip_address = join('.', unpack('C4',(gethostbyname($host))[4])); However, it does not work if it is an IPv6 only domain name such as "ipv6.google.com". How can I get one line of code (prefer CORE library) to get IPv6 IP address? $host = "ipv6.google.com"; $ip_address = ??? 回答1: In 5.14 and above, you can use the core Socket: use 5.014; use warnings; use Socket (); # protocol

expand ipv6 address in shell script

问题 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? 回答1: 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
