Re: [IPv6] Comcast IPv6 Address Assignment/Delegation said by biomesh:My guess is that users will setup guest vlans or networks.
This is what I am doing as well..
said by biomesh:This could also be used for vpn configurations in order to isolate their 'business network' from their 'home network'.
This is totally the type of innovation I was looking for in that comment.. I didn't even think about a VPN type VLAN back to the office.. |

| said by NetDog:This is totally the type of innovation I was looking for in that comment.. No, the way you phrased it and stated the obvious ("If not there is no point in asking for anything less then /64") it was clearly a challenge while saying you didn't think there was any reason to request something larger then a /64.
Of course there are multiple VLANs attached to it; I wouldn't be requesting something larger then a /64 otherwise. All the PCs and tablets are on one, a "guest" network is another, there are 4 or 5 VoIP phones and an Asterisk box on yet another, a locked down network that's only used for cleaning viruses, and while it's not really used any more, yet another is set up that had a couple file servers/NAS boxes on it.
Yes I'm aware that's only 5, and yes I'm aware that a /60 can be broken into 16 subnets, but there's no reason to be stingy with v6 addresses like there is with v4's and I like having elbow room to handle whatever tomorrow throws at me. I prefer to configure stuff once and not look at it again for quite a long time 
I considered the VPN angle, but for my needs there's no reason to have an internet routable address assigned to that interface.

Boynton Beach, FL | While I'm glad Comcast is going to give out a /60, and I'm not trying to pick on you personally, but you're saying 295,147,905,179,352,825,856 IPv6 addresses just won't be enough for say 256 real / virtual devices in the home? |

Each VLAN or routed segment should be a /64 for the foreseeable future (netstacks stink, even without SLAAC in use). Which is why some segment (edit: network-pun unintended) of Comcast's residential users will need a /60. |

Boynton Beach, FL | Oh I'm sure we can come up with all sorts of nifty ways to use routable IPv6 segments, but from the home user perspective, I think most other than a truly isolated guest network are probably more a product of tinkering rather than a definable need. I think Comcast's approach of providing additional routable segments only to those that request and know how to with DHCP-PD to be a very good compromise. Its far more than I personally was expecting from any decently sized residential provider to offer. |

I wasn't aware that U-verse was offering native IPv6 at this point, though admittedly I don't follow it as closely as I once did. If they are now offering it to residential U-verse subscribers that is good news indeed. We might just get this IPv6 migration thing done in under two decades after all. |

It isn't native yet. They're using 6RD. |
