Re: [IPv6] Comcast IPv6 Address Assignment/Delegation

My guess is that users will setup guest vlans or networks. 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..

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.

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.

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.

On Uverse, AT&T offers a /60 for each IPv4 address you have.

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.
