IPv4 and ASN Policy draft on-line Enterprise & full IR policy doc

Dear Kevin,

Enterprise LIRs are treated the same way as any other LIRs. There are
no special policies or procedures that only apply to Enterprise
LIRs. There are also no specific guidelines for Enterprise LIRs for
this reason.

The issue you raise about Assignment Windows for organisations that
only assign to their own infrastructure has been raised in the past in
the lir-wg. As you point out, this does not only affect Enterprise
LIRs but any LIR that makes assignments to its own infrastructure
(cable providers are an example of this). We have discussed this issue
together with the lir-wg chair (Hans Petter Holen) and we are looking
to find a solution that would meet this need. I believe this will be
discussed at the upcoming RIPE 40 meeting. 

In the scenario that you describe where part of your organisation is
assigning address space to another entity, you are more or less free
to choose for any of the options that you describe. There are no
guidelines or policies on this, but depends on your needs and future
plans.

To further discuss a solution that suits your needs, and for any other
unresolved issues in your particular case, please write to
<lir-help at ripe.net>.

Kind regards,

Nurani Nimpuno

 * All,
 * 
 * I would like to ask for advice and comment, and suggest it Is probably time
 * for a discussion about the differences in operations of the two types LIR's,
 * i.e. with the status of "enterprise" and "full".
 * 
 * The current RIPE NCC documentation offers conflicting or no advice - I
 * cannot find any specific enterprise registry instructions / guidance, except
 * for the line "....large international Enterprises can also operate Local
 * IRs".
 * 
 * I would expect to see something in either Ripe 212 (Guidelines for Setting
 * up a Local Internet Registry) or Ripe 185 (European Internet Registry
 * Policies and Procedures).
 * 
 * Given that IPv4 and ASN policy document is now under review I think that
 * this is a good time to raise this issue again, and hopefully get something
 * agreed in writing. 
 * 
 * Therefore I am specifically looking for "Enterprise Registry Assignment
 * Policy instructions".
 * 
 * I'll try briefly to give the background and a flavour of the issues.
 * 
 * As a large company we operate several LIR's: 
 * 1. 	A public Internet Service with a large allocation (many /16)
 * 2. 	Several small LIR's - product / site / country / subsidiary
 * specific. 
 * 3. 	A large enterprise Registry (several Ripe /16 with both PI and PA
 * ranges and historic UK address space originally assigned by ARIN)
 * 
 * These registries are not all necessarily managed by the same teams nor do
 * they all necessarily have specific interfaces with each other. The internet
 * connectivity for them all is not via the same ISP, but the enterprise
 * registry (3) does route via the Public Internet Service ISP (1).
 * 
 * For an enterprise registry, assignment window size is irrelevant because all
 * address space used will be assigned within the company "owning" the
 * registry. Therefore a RIPE 141/219 is required for every assignment (this is
 * policy for normal registries using addresses for their own infrastructure).
 * Consider the scenario where an enterprise registry is allocated a block of
 * addresses that it will only ever assign to its own company, and that the
 * enterprise registry advertises & routes the whole block and assigns subnets
 * from it to departments within the company where required. For all practical
 * purposes all of these addresses are used by and assigned to the same place.
 * 
 * In our case, problems involving the daily recovery/reassignment of subnets
 * was overcome by agreeing a large corporate assignment window with the
 * hostmaster and by keeping the number of addresses assigned to departments /
 * groups / projects within that number -and then asking for an assignment
 * increase where necessary.
 *  
 * But what can an enterprise registry's addresses be used for?  
 * *	its own company infrastructure 
 * *	server farms and web hosting ( thus being used indirectly by
 * customers of the registry's company), and
 * *	various other uses - but not onward assignment to "paying"
 * customers.
 * 
 * Following several previous discussions between myself, my colleagues and
 * with various RIPE NCC hostmasters it has been agreed that 
 * RIPE NCC will now allow us to transfer  "experimental" addresses (obtained
 * from our enterprise Registry), which are used by a department within the
 * company,  into "commercial" status - when the service offering changes from
 * experimental to commercial. This means that systems using these addresses do
 * not have to renumber to the range assigned by the public ISP. 
 * Therefore I would like to see this policy formalised within RIPE NCC
 * documentation.
 * 
 * And my next question is: 
 * 
 * If this department splits from the original company and becomes a separate
 * entity, what happens to the addresses space it uses?
 * There are several possibilities:
 * 1.	Migrate from the enterprise registry to the public ISP or another
 * ISP (over a reasonable time period - but this could involve considerable
 * pain/cost), or
 * 2.	Continue to use the enterprise registry address space, and then the
 * "enterprise" registry converts to a "full" registry, but what are the
 * implications? or
 * 3. 	Split the enterprise registry into 2 (not contiguous ranges) and
 * create another LIR. 
 * 
 *
