Hi, is this issue still valid? I see something similar was fixed in #35, but I encounter the same problem on IPv6-only server with DNS64 transition mechanism enabled.

If I use curl on the same server, it works as expected:

$ curl -I https://registry.npmjs.org/commander

...

Is it possible there is some hard-coded IPv4 method in npm install?

It seems that npm still failed under ipv6 only network. The DNS resolves IPv6 + IPv4 addresses correctly at the same environment but npm or some components used by npm choose IPv4 somehow.

Env

Docker Image:

node:lts-alpine3.10

[NeverBehave]

After dig into this issue deeper it seems like a nodejs behavior: nodejs/node#31567

For now, my work around will be adding some line to /etc/hosts hard-coded some ipv6 entries for npm to fetch stuff, as stated in the archived forum

Dive even deeper I found this issue seems to happen only on alpine based image, node:current-buster seems fine.
It looks like something related to musl DNS resolver
