APNIC membres and WIDE members had a meeting about sTLA allocation.
This is the meeting log.
APNIC and WIDE 6bone registries meeting
Wednesday 17, March 11:30-
Definition of draft.
Definition of IX.
Definition of site.
What is ISP , IX , site ?
Clear definition of ISP and other sites.
Condition of providing sTLA IDs.
2 pTLA are exit in Japan.
WIDE & NTT.
WIDE includes some commercial ISPs.
Static assignment for dial up connenction.
Address Binding.
Is it a lifetime lease ?
Is it a IPng's issue or Registries' issue ?
It's a registries' issue.
Renumbering
renumbering is untested.
expect to determination.
Renumbering sTLA to TLA in 3 month.
Motivation to develop Router Renumbering and auto router
configuration mechanism.
But for developpers not for users and ISPs.
Renumbering is too hard for ISPs.
Considering for customer.
No experience of renumbering in large scale.
Slow start.
We consider to run out sTLA.
initial assignment = 50
Condition for getting a sTLA ID.
How many ISPs which meet the conditions
do exist in 6bone-JP ?
about 4 sites.
Address Allocation
Initial allocation = /35
it is convenient than /29.
50 initial assignment.
Future allocation
Provide 50 sTLA ISs for bootstrap priod.
Registration base providing.
starting is slow allocation step by step.
An idea in case of running out sTLA.
1. split another TLA into sTLA.
2. split another sTLA into smaller range.
3. revoke under utiluzed alloc.
Registries think that 2 is best strategy.
Motivation.
Difficult to define of verify criteria.
Fair start to everyone.
Future alloc.
Routing Problem.
Incremental scale of prefix lengths establishes various
prefixes.
Can be used to make rational decisions on routability.
Rational decision is impossible under only 2 prefixes.
(TLA & sTLA)
ISPs prefix.
Registries define many various prefixes.
Next steps.
New draft out in two or three weeks.
Circulate membership.
Membership is important.
-> Anyone who wants sTLA IS should be a
membership.
Registries will start to alloc sTLA in 1st May.
Reverse DNS.
Deligation issues.
/35 is better for deligation.
The setting of DNS Delegation
Many delegation point of DNS are required.
DNS operation.
The registries are resposnsible for delegation of DNS.
We should consider DNS operation.
Initial routing prefix = /35
If a site want an another sTLA ID, the registries give
a sTLA ID which has shorter prefix.
Delegation point will be canged
corresponding the lenght of sTLA ID.
/35 2
/34 4
/33 8
/32 1 <- It is easy to operate.
APNIC membership
IPv6 membership same as IPv4 membership.
Aggregation points.
+-------+-------+-------+----------------+
0 1024 2048 3072 8192
Defferent memberships at each aggregation point.
Minimam allocation of NLA ??
Why /35 ?
/19 /32
IPv6 +--+----------------+-----------+
sTLA NLA
19bits 13bits
/19 /32
IPv4 +-------------------+-----------+
19bits 13 bits
Network ID Host ID
Same as IPv4 prefix.
