@DigitalBrainJS Hey, any chance you could take a look at this please? Axios@1.0.0 up to current broke support IPv6 literals. I've had to resort to using 0.27.2 due to this for certain codebases.

@jasonsaayman @DigitalBrainJS Any chance you could please look at this one, at least approve it to run on CI to see its outcome. Thanks.

@ssbarnea I've published this under six-axios(https://www.npmjs.com/package/six-axios) for now as I need the support while waiting for someone from the team to be able to look at this PR. Hopefully others can find use of it. You can do "axios": "npm:six-axios@^1.6.8" in your package.json to avoid having to rename everything in your code. Hope this helps!
