[0sdavison]

Version

v22.12.0

Platform

Microsoft Windows NT 10.0.19045.0 x64

Subsystem

dns

What steps will reproduce the bug?

const dns = require("node:dns");
dns.lookup("localhost", { all: true }, console.log);

How often does it reproduce? Is there a required condition?

Always

What is the expected behavior? Why is that the expected behavior?

In node v22.11.0, both IPv4 and IPv6 addresses are returned:

null [ { address: '::1', family: 6 }, { address: '127.0.0.1', family: 4 } ]

What do you see instead?

In Node v22.12.0, only IPv6 addresses are returned:

null [ { address: '::1', family: 6 } ]
