From 3716311dd82fa5a3fc592fb9d95c87f7f9afb930 Mon Sep 17 00:00:00 2001 From: wouter bolsterlee Date: Mon, 4 May 2026 15:03:20 +0200 Subject: [PATCH] gh-87245: Improve IPv6Address.ipv4_mapped documentation (GH-92572) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Avoid the phrasing ‘starting with ::FFFF/96’, which is confusing since it seems to mix a prefix and a range. Instead, make it clear what the actual range is, and refer to the relevant RFC. Closes GH-87245.
