RFC 9758, "Updates to the 'ipn' URI Scheme", May 2025

Errata ID: 8610
Status: Verified
Type: Technical
Publication Format(s) : TEXT, PDF, HTML

Throughout the document, when it says:

2^(32-1)

It should say:

2^32-1

Notes:

2^(32-1) = 2^31 = 0x80000000, but the intended value is 2^32-1 = 0xFFFFFFFF.

The Registration Procedures for the 'ipn' Scheme URI Allocator Identifiers Registry and the Registration Procedures for the 'ipn' Scheme URI Default Allocator Node Numbers Registry use >=0x100000000 instead of >=0x80000001 as the largest range. Other parts of the text show that 0xFFFFFFFF is the intended value:

* Section 4 says 4294967295
* Section 6.3 says
allocator-identifier: uint .lt 4294967296,
node-number: uint .lt 4294967296,

Also note that Section 3.4.2 shows 0xFFFFFFFFF = 2^36-1 (nine F's instead of eight).
