Could someone from Microsoft AS8075 reach out to us off list? We've been having a number of customers complaining because their Xbox is saying it "Can't get a Teredo IP address". Seems to be related to the DNS response the client gets, as we've been able to work around the issue by trying different DNS providers. One of our network admins has been battling this while I've been out on vacation the past two weeks. Some of the customers are able to replicate the issue when using their cell provider, so it's not limited to just our network having this issue. We have some packet captures we can share, and an employee who is able to replicate the issue at their house for further testing. Attempting to contact Microsoft via other routes hasn't gotten him anywhere. Thanks, John Stitt HES energynet
