ARIN-prop-188 LIR/ISP and End-user Definitions
Proposal Originator: Scott Leibrand
Date: 2 May 2013
At ARIN 31, the Policy Experience Report (slides at https://www.arin.net/participate/meetings/reports/ARIN_31/PDF/monday/nobile_policy.pdf or https://www.arin.net/participate/meetings/reports/ARIN_31/PPT/monday/nobile_policy.pptx) reported that, in ARIN staff's experience, the NRPM does not adequately define ISP/LIR vs. end-user. As currently defined, and interpreted literally, many companies do not qualify as either LIRs or end-users. I would propose that the primary difference between ISPs/LIRs vs. end-users, for purposes of the NRPM, is whether an organization reassigns address blocks to third parties. If an organization maintains full control of all of the equipment on its network, and doesn't need to make any reassignments to other organizations, then it can qualify as an end-user. In particular, an end user organization can supply a full list of all the IP addresses in use on its network, and know what devices are using those addresses.
An ISP/LIR, on the other hand, should be defined by whether they delegate that responsibility to another organization. In that case, they need to reassign the network space via SWIP/rwhois, which makes them an LIR. Additionally, there are likely some ISPs that do not (yet) need to delegate any address blocks, but which assign address space to users (rather than to their own equipment), which should also fall under the definition of LIR/ISP.
Update NRPM 2.4 and 2.6 to read:
2.4. Local Internet Registry (LIR) / Internet Service Provider (ISP) The terms Internet Service Provider (ISP) and LIR are used interchangeably in this document. A Local Internet Registry (LIR) is an IR that assigns address space to the users of the network services that it provides. Therefore, LIRs / ISPs are organizations that reassign addresses to end users and/or reallocate addresses to other ISPs/LIRs.
2.6. End-user An end-user is an organization receiving assignments of IP addresses exclusively for use in its operational networks, and does not register any reassignments of that space.
