DNS requests appear to be intercepted
In testing a DNS issue, I appear to have discovered that my DNS requests are being intercepted. When I query a DNS server that is an authority (confirmed by performing the query with another internet provider and also confirmed by a friend who is also on Xfinity), I'm receiving a response that the answer is non-authoritative. The other Xfinity user is using a bring your own modem. I am using the Arris TG3482G. Is the interception being done by Xfinity? Is this intentional?
