Use public IP in link

[ianhi]

Is your feature request related to a problem? Please describe.

I'd like to be able to launch a notebook on my laptop, and give a labmate or student sitting nearby access to edit. However, the default URL when l use Share will be localhost so I have to:

1. Use ifconfig (no idea what I would do on windows)
2. extract my IP address
3. manually replace it in the URL

Describe the solution you'd like

Add an option (or even as default) to replace localhost with my IP address (maybe with a checkbox for private/public IP)

Describe alternatives you've considered

Manually doing this, or building a script that autoreplaces this for me

Additional context

• Python package version: 0.2.4

• Extension version: 0.2.4

• Operating System and its version: popos 21.04
