Unresolved domain names while docker build

What to do when you have github.com or chocolatey.org cannot be resolved when you try to do docker build.

Multiple possible course of action:

• use --add-host argument in the build to give resolution

• use --network "Default Switch" argument, to specify to RUN commands which network to use

• add in dockerfile, for example:
  

RUN echo 104.20.73.28 chocolatey.org >> "C:\Windows\System32\drivers\etc\hosts"

• set DNS for IPv6

Hope this helps !
