[AusNOG] IPv6 Addressing Schemes

One suggestion I heard that I like.
Make the network that has your local DNS servers, your zero'th subnet.
So you can take advantage of zero summary in ipv6.
i.e. local DNS to be "prefix_from_apnic::1"

Hi Shane,

Maybe consider: http://tools.ietf.org/html/rfc2374 

"The SLA ID field is used by an individual organization to create its
own local addressing hierarchy and to identify subnets.  This is
analogous to subnets in IPv4 except that each organization has a much
greater number of subnets.  The 16 bit SLA ID field support 65,535
individual subnets."

You could reserve some bits from here to identify the region within the 
Asia Pacific, location within the region, etc.  You could put other
in here, too (customer vs infrastructure?).

	Howdy Guys,
	We've got our /32 from APNIC a while ago, I'm now finally
looking to begin rolling this out across the network and to be honest,
the sheer amount of space is doing my head in a little..
	I did a bit of a google around and I couldn't really find any
'best practice' for splitting up a subnet of this size..
	How're people here picking which subnets to allocate customers?
are you splitting it up into chunks of /48s,/56's and /64s and handing
them out sequentially?

Kind Regards,
