On a Linux system you can add a second IP address to a device to access 
a second network:

    *Second/Alternate IP address – two network address:*

    sudo ip addr add broadcast dev enp1s0

    Temporarily (clears at boot) adds this address to current device.
    Allows connecting to different LAN. (so and

"enp1s0" is my ethernet port per ifconfig.  I am not certain of the 
'24'; may need a smaller number -- I sort of know what it's for but not 
enough to start to explain.  *.*.4.* is the original network here; 
*.*.0.* the alternate.

(And I thought I was bowing out of this thread! <g>)
