ipv6

On startup, my program calls getifaddrs() to find out what network interfaces are available for link-local IPv6 multicasting. This works as far as it goes, but it doesn't handle the case where the set of available network interfaces changes after getifaddrs() has returned. Is there some way for the OS to notify my program when the network interfaces have changed, so I can call getifaddrs() again and update my list? Or am I doomed to poll getifaddrs() every few seconds, forever? (Note: on Windows, I call GetAdaptersAddresses() instead of getifaddrs(), but the same issue exists there) You

This is a slightly obscure question, but I'm stumped and I thought maybe somebody out there might have more of a clue on the issue. My co-worker has been successfully running an in-house application that uses IPv6 multicasting on his MacBook Pro for several months, but today the Mac decided to stop routing the multicast packets. In particular, the program prints this error: SendDataUDP(ff02::bead:cede:deed:feed@4) failed on Network interface [Name=[en0] Description=[] IP=[fe80::222:41ff:fe21:dfd4@4] Netmask=[ffff:ffff:ffff:ffff::] Broadcast=[::]] (errno=65/No route to host). ... which pretty

I have many projects with functionalities relying on IP addresses provided by $_SERVER['REMOTE_ADDR] , $_SERVER['HTTP_X_FORWARDED_FOR'] , and $_SERVER['CLIENT_IP'] . IPV4 addresses are easy to match since we always receive them in the same format: 4 integers without the leading 0s, separated by a dot . . Whereas IPV6 addresses can be compressed. Ex: FF01:0:0:0:0:0:0:101 -> FF01::101 I've been researching this issue but haven't found anything relevant, so I'm asking for your experience. Is $_SERVER['REMOTE_ADDR] using a standard? Is it safe to assume that it will always be received as

I would like to know, whether there is a library which I can use to convert a represenation of a long IPv6 address (such as 2002:9876:57AB:0000:0000:0000:0000:0001) into the compressed IPv6 form (in this case: 2002:9876:57AB::1). I was not able to find such a library. This library should not use any IP Api, a network connection must not be made. I already tried return Inet6Address.getByName(longAdress).toString(); but this just replaces the 4 zeros with 1 zero (in this case 2002:9876:57AB:0:0:0:0:1). any suggestions? public class Ipv6AddressCompressor { public static String

I have an iPhone game in Appstore, I recently tried to upload an updated build with latest Xcode but it was rejected because the inApp-purchases were not working on ipv6 only network. It's working fine with ipv4 network. // // ViewController.m // NSMutableArray * arrayOfSection; NSMutableArray * sectionHeaders; NSString *error; #import "CoinsController.h" #import "NSString+SBJSON.h" #import <CommonCrypto/CommonDigest.h> @implementation CoinsController @synthesize bkg; -(void) callPurchaseId:(NSString*)iapId amount:(NSUInteger)ncoins{ SKPayment *payment = [SKPayment paymentWithProductIdentifier

I have apps, built 2015 and 2014. How can I test them for IPv6? If my apps doesn't support IPv6, what should I do? My apps are using AFNetworking and Alamofire. I'm connecting mostly to domains ( Ex. api.example.com/v1/...). Only 1 app use IP: (ex: 12.12.12.12:3000/api/v1/...). Is there problem for websockets? (ws://12.12.12.12:8080/api/....). It is hard to say with any certainty without knowing more about your app. Specifically: Are you using IP addresses directly? Are you allowing users to enter them directly in some form other than in a URL? Are you making network connections directly using
