[AusNOG] Should we be a LIR for our customers and get them PI (Was: another ipv6 Q)

[Tony]

Hi,

I am still confused I think.

As an SP we currently have a /32 from APNIC that is (I assume) from PA space and so it should only ever be announced as a single /32 by us. This means that any sub-allocations we might make to our customers are not provider independent and so if/when the customer moves on they need to return the address space to us and renumber using the address space provided to them from their new SP.

Assuming one of our customers (the larger ones that have multiple sites, and hundreds of devices) meet the APNIC criteria for their own PI space so that they never have to renumber IPv6 space when they change SP, there would appear to be two options:

1. Customer becomes APNIC member and applies to APNIC directly for PI space. Assuming the meet the criteria (and pay up) they will get a /48 of PI from APNIC - problem solved, costs customer annual APNIC fees.

2. We assign the customer some PI space (that is then theirs forever). We can't/shouldn't do that out of our existing /32 and so would need to apply for some more space from APNIC that is able to be assigned as PI to our customers who request. Once we have this additional address space we would assign it in /48's to our customers who wanted this (assuming it was justified). We could either apply for a larger chunk at once to divide up for all of our existing and future customers that require it, or apply in /48 chunks each time.

Can we get more space from APNIC for assigning as PI or do we need to get our /32 "converted" to be from the appropriate pool ? We haven't gone too far yet into actually using our /32 so wouldn't be too much grief to do this at  this stage. I do need to know though if this is the correct way to go about it. We're also unlikely to use a /32 even if we're "giving away" /48's to large customers that then leave us at some point in the future. I'm fairly sure there is enough in a /32 to go around. Yes, I guess having customers IPv6 networks numbered out on OUR non-portable space might help to lock them into us by making it hard to change providers, but if this is the only reason they are staying with us as customers then we are doing something wrong.

I could ask APNIC directly, but I also know there are some peoples from APNIC that read this list, perhaps they are able to respond about what can/can't/should be done for the benefit of all in this scenario ?  Am I unique in my questions ? Has this come up before ?

Perhaps we should be just telling our customers to foot the bill and get their own IPv6 PI space and stay out of the middle (and just advertise it for them as required). If this is the case though we still need to know this, so we can recommend to customer that this is what they should be doing. The only reason we'd look to do it on their behalf (option #2 above) would be to simplify it for them. I'm not too concerned about cost to the customer, if they can't manage an extra $1200 PA for IP address space then they probably aren't big enough to be trying to justify PI anyway (although if it's a cost we can help them avoid at no expense to us, then why wouldn't we help them).

As someone said, in terms of routing table sizes, if a /48 is going to be advertised it doesn't matter what space it comes from, it's still going to be another /48 in the table.


Thanks,
Tony.

Why not just tell apnic you made an error, you meant to get PI space so you can allocate blocks to customer sites and find out what the process is to convert it.    I can't see them saying no, you'll reduce your overhead and you'll use the space as intended with /32+ for providers, /48 per site and your customer has tons of /64s to use at each site.

To get another /32 you'll need to justify it and from this conversation it sounds like you might have a problem proving your 80% in use.

I don't know, with a shiny new NBN fibre NTU with 4 ports that I can easily get concurrent connectivity from 4 separate ISP's if I wanted to, perhaps I might just need my own /48 PI at my house :)

Thanks for the info. So we just apply for PI space on customers behalf that will then be outside of our /32 and bill them (if we so choose) the incremental cost for their PI allocation (eg. /48) ? Given our IPv4 space, we can apply for a metric-bucket-load of extra /48's before we would end up paying any more in annual fees to APNIC.
