IPv6 question in ATL market

Hello.  It is very difficult to find information about IPv6 and IPv6 support.  I see from many postings since 2013 that Comcast will allow users to request via prefix delegation (PD) a /60.  When I set my prefix length to /60 -- all it seems I can receive is a /64.  Is that expected behavior?  Does anyone have any idea who to contact or how to escalate an IPv6 question--customer service wants to help, but they have no idea how to escalate a ticket.

 

If a /64 is all that is available, that would be good to know.  According to many posts online, it seems like Comcast has set up their Arris CMTS's to delegate up to a /60.  And if you use SLAAC, a /64 is basically one flat network--and i have a need to experiment with multiple IPv6 subnets.

 

Thanks!

Hi there, Dave_in_atl. 

 

Thank you for reaching out and posting. I looked into your questions and it looks like residential services are locked at the /64, like you stated.

FWIW, I remember in the past that customers could hint for a /60 as well as a /64 prefix but I Guess that they must have phased that out.
