[BUG] Fix IPv6 records for npm

[EduApps-CDG]

Is there an existing issue for this?

• I have searched the existing issues
• • [BUG] Npm install ETIMEDOUT #4085 (probably the same)

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

I'm trying to install natural package, but npm freezes in sill idealTree buildDeps (Not the same behavior as #3257, so I suppose it's another bug). After some minutes it returns ETIMEDOUT.

Expected Behavior

npm should install the package (it's also unable to update npm itself).

Steps To Reproduce

1. Start a empty project
2. Run npm i [any package]
3. See error similar to this:

npm ERR! code ETIMEDOUT
npm ERR! syscall connect
npm ERR! errno ETIMEDOUT
npm ERR! network request to https://registry.npmjs.org/natural failed, reason: connect ETIMEDOUT 2606:4700::6810:1223:443
npm ERR! network This is a problem related to network connectivity.

I'm not in a proxy and websocket connections are okay in web browsers

[EduApps-CDG]

npm ping does the exact same thing

[EduApps-CDG]

deleted .npm folder, the exact same happens (and does not search for updates in 8.1.4)

[EduApps-CDG]

Everything fine on a Google Colab machine (outdated versions). But I still have the issue can someone help me?

I can't figure out why it works on 7.18 and not in 8.X.

Reinstalled npm, same problem (this happens with yarn too)

Important Update:

Installed latest LTS version of node with npm@8.1.2 and npm@8.3.0 and everything is working fine, I think it's not an npm bug now, but a node bug. See nodejs/node#41145

I see that registry.npmjs.com is advertising IPv6 addresses in DNS. I'm guessing that they are only serving over IPv4 and the problem you are seeing is due to a breaking change in Node.js 17.0.0's dns module.

If I'm right about this, the thing to do would be to either enable the registry to serve over IPv6 or else do not advertise the DNS records over IPv6.

Oops, sorry for the ping, @aduh95. I thought it was you that made the change, but I see it wasn't.

I'm back, It looks like there is something wrong with npm registry domain:
