Draft Policy ARIN-2025-7

---

Current Text (4 February 2026)

Problem Statement

6.5.8.2 states “An organization qualifies for an assignment on the next larger nibble boundary when their sites exceed 75% of the /48s available in a prefix.“and then follows with “For example: More than 1 but less than or equal to 12 sites justified, receives a /44 assignment;“implying that a single site should only receive a /48. However, 1 /48 exceeds 75% of the /48s available in a /48 (1), so per the rule an organization with a single site should receive a /44, which differs from the example.

Policy Statement

Change the sentence “The initial assignment size will be determined by the number of sites justified below.”

To: “Larger initial assignment sizes will be determined by the number of sites justified below.”

Resulting with:

Organizations that meet at least one of the initial assignment criteria above are eligible to receive an initial assignment of /48. Larger initial assignment sizes will be determined by the number of sites justified below; an organization qualifies for an assignment on the next larger nibble boundary when their sites exceed 75% of the /48s available in a prefix. For example:

• More than 1 but less than or equal to 12 sites justified, receives a /44 assignment;
• More than 12 but less than or equal to 192 sites justified, receives a /40 assignment;
• More than 192 but less than or equal to 3,072 sites justified, receives a /36 assignment;
• More than 3,072 but less than or equal to 49,152 sites justified, receives a /32 assignment; etc…

Timetable for Implementation

Comments

Based on community feedback, the policy structure was reworked to state that a single-site organization receives a /48, and then the 75% formula applies to multi-site organizations, rather than framing the /48 as an exception.
