I've heard during a CCA course that in Europe we have to enable also Akamai ip addresses to receive Apple Push Notifications and so there will be no more errors. I cannot find the Akamai ip addresses ranges to use...
Could somebody help me? Many thanks
i did some research. Akamai IP ranges are always a pain to check.
But you should be able to get started with this page: http://www.base64online.com/ip_address_range.php?descr=Akamai%20Technologies
A full list is here, but seems that is a bit too much to add in your firewall. http://tools.tracemyip.org/search--isp/akamai+technologies
BTW: Congrats on passing CCA
I may be wrong, but apple don't use Akamai for APNs
I think it uses it for connectivity check when you connect to Wi-Fi (to check if there's a portal or if internet really works). I'm not too knowledgeable on this matter as I believe it's not public.
