[ppml] RIR shopping -- AND MORE

[Einar Bohlin]

RIR shopping?  Check this out:

The initial IP allocation policies for ARIN and APNIC both
get you a /20 (see below for more info), but the
requirements and what you have to do after you
get the net are different.

The fastest way to get your own IPs:
ARIN - Be multihomed and using a /21
APNIC - Be using a /22 (or need one today)

Assuming the ISP wants to renumber into their
own nets, what renumbering are they faced with?

            best case                 typical worst case
ARIN           /21                       /20 or more
APNIC  zero renumbering needed               /22

Note that ARIN stipulates that the ISP needs to use the
entire /20 in 3 months, APNIC only wants a /21 to be used
within a year.

If I were a new shopper with the ability to do so, 
I'd have to consider APNIC.

IMHO ARIN's more strict policy is outdated; it
applied to a time when registering IPs was fashionable.
APNIC's policy is more reasonable.

It would be great to be able to allocate IPs based
on up to a year's utilization.  Recently a downstream got
a /23, then a follow up /22 and now wants more; those routes
add up.  Where is the harm if we'd initially allocated a larger
range, corresponding to a longer timeframe of use.

ARIN http://www.arin.net/policy/ipv4.html#ispinitial [/20]

The efficient utilization of an entire previously allocated /20 from their upstream ISP.

[or]

Multi-homed organizations that have efficiently utilized a /21 may be allocated a /20. In order to receive an initial allocation from ARIN, multi-homed organizations must:

Provide detailed information showing that a /20 will be utilized within three months. 



APNIC http://www.apnic.net/docs/policy/add-manage-policy.html

9.3 Criteria for initial allocation [/20]
To be eligible to obtain an initial allocation, an LIR must:

have used a /22 from their upstream provider or demonstrate an immediate need for a /22; 
have complied with applicable policies in managing all address space previously allocated to it; 
demonstrate a detailed plan for use of a /21 within a year; and 
commit to renumber from previously deployed space into the new address space within one year. 

9.4 Criteria for subsequent allocations
After the initial allocation to an LIR, all subsequent allocations will depend on the following:

the LIR's verified usage rate (which is the rate at which the LIR made assignments and sub-allocations from relevant past allocations); 
their documented plans for address space; and 
their degree of compliance with APNIC policies with respect to relevant past allocations. 
Based on these factors, APNIC and NIRs will allocate enough address space to meet the LIR's estimated needs for a period up to one year. If APNIC or the NIR make an allocation based on a period of less than one year, then they must inform the LIR of the length of the period and the reasons for selecting it.
