As I understand it, the IP range 100.64.0.0/10 is restricted for use by Internet Service Providers, within their own networks.Therefore, we should not see any traffic with destination addresses within this space on a private network that connects to a Public IP.Examination of the logs of internal network traffic at a customer shows these destinations occasionally (e.g. one or two firewall logs in four days), mainly from iPhones and Android devices.Should I be suspicious of this traffic?Should I permanently block the 100.64.0.0/10 range in all firewall Policies (from both Trusted and Untrusted BYOD networks)?Thoughts and advice, anyone? This is posted in the Vodafone forum as the customer in question is a Vodafone customer, and there may be some VF-specific answers - but this is also a general question for any network.Same site as this previous forum post (possibly related issue)https://www.geekzone.co.nz/forums.asp?forumid=40&topicid=248531
