Hi list Any help will be appreciated, it seems that apple is filtering prefixes for untraceable reasons I wrote emails to Apple-NOC@apple.com droot@apple.com but no answer. Staring about 2 weeks ago we encountered several complaints from our customers which are using 188.24.168.0/21. The prefix is allocated to our residential customers, dynamically via pppoe. Actually they are not able to connect AppStore and associated resources like developer.apple.com from their IOS terminal phones or tablets, nor using iTunes or browser from their respective operating systems. Using tcpdump we saw that 17.154.66.17 is not responding to client request. IP 188.27.253.245.63289 > 17.154.66.17.443: tcp 0 Furthermore we did manage to ping hosts from 188.24.168.0/21 using a looking glass server (4.69.185.226) from LEVEL3 San Jose which seems to be last hop provider to apple network. Ping results from San Jose, CA to 188.27.248.26(188-27-248-26.rdsnet.ro) icmp_seq=0 time=188 ms ---- statistics ---- 1 packets transmitted, 1 packets received, 0% packet loss rtt min/avg/median/max/mdev/stddev = 188/188/188/188/0/0 ms Regards, -- Mihai NECSA network engineer @AS8708
