IPv6 and passthrough mode

Hello all,

I just spoke with a Comcast technical representative and they clarified that Comcast currently does not offer IPv6 addresses when a customer modem is in pass through mode as it requires DHCP enabled and managed on the modem and that passthrough is the demarcation line so it's on the customer.  It would be helpful to know what others have done in this situation. For example, did others just add the additional bridge layer and how much effort that was or they found another way. As an aside, currently there is a block of 5 static IPv4 addresses. I appreciate any of your thoughts. Thanks.
