The term ISP is used in the ARIN region but is also defined in such a way as to 
be almost synonym of LIR. In other regions, the term LIR is used in a different 
manner.

2.4. Local Internet Registry (LIR)
A Local Internet Registry (LIR) is an IR that primarily assigns address space 
to the users of the network services that it provides. LIRs are generally 
Internet Service Providers (ISPs), whose customers are primarily end users and 
possibly other ISPs.

LIR = 27 Times in NRPM
ISP =  72 Times in NRPM

The majority of LIR use is in IPv6 and the majority of ISP is in IPv4.

Maybe a proposal to pick one would be in order, but until then I don’t think it 
matters as long as it is consistent with the wording used in the section.

Thanks,

Kevin Blumberg

I’d argue the opposite - when crafting policy, we must be precise in our 
language, and in general we must avoid ambiguous terms, unless there’s a 
specific goal to leaving a section of language open for interpretation (and 
even then, it must be clear whose interpretation reigns supreme).

I’m a fan of the term LIR, even if it is somewhat abstract. Language clearly 
linking the two terms, defining an ISP as the most common example of an LIR, 
would be helpful as well.

This has gone back and forth over the years, some people think "LIR" is too 
abstract and some people think "ISP" is too specific. While ISP doesn't have 
it's own subsection under definitions it is discussed under "LIR", section 2.5, 
so I wouldn't say it's undefined. I think it's probably dangerous to make a 
hard and fast rule either way.  I think it is probably best to think of "ISP" 
and "LIR" as synonyms, at least from an ARIN policy perspective, but just like 
many synonyms they have subtly different connotations.

Thanks.

The following has been revised:

* Draft Policy ARIN-2017-5: Improved IPv6 Registration Requirements
[snip]
4) Add new section 6.5.5.4 "Registration Requested by Recipient" of the NRPM, 
to read: "If the downstream recipient of a static assignment of /64 or more 
addresses requests publishing of that assignment in ARIN's registration 
database, the ISP should register that assignment as described in section 
6.5.5.1."

I have been under the impression that a common goal of most people proposing 
NRPM changes is to eliminate the use of the term "ISP", since it is not defined 
in the policy and most or all the relevant sections also apply to other 
organizations that, while they re-allocate or reassign address space, are not, 
properly speaking, ISPs.  Shouldn't this says "LIR" or "provider" or some other 
more generic term?
