How to xpose docker container to local network

[nuggit]

I'm looking to run some selenium tests on my local secured network. 

I'm running all of this on my laptop which is a windows machine.  I'm running a Docker linux container though.

I'm using a selenium-grid and can prove it is setup properly to run a simple test like navigate to Google and Assert on Title of page.

When I change my url to goto an internal Website (say testsite.domain.com) it appears it cannot resolve the DNS entry.  Digging thru documentation I'm a bit confused on what I'm not doing correctly.

Any direction on what I may need to do to get this to work would help.
