Are you behind a router?

Also, if you open cmd.exe and type 'ipconfig /all'
you will see lists of different numbers

If you have internet from your Ethernet Port: find the LAN Ethernet Adapter

If you have internet from wireless: find the WAN adapter

Look if your IPv4 address is 192...something

if it is, there's a good chance it's impossible for you to host directly from pc because 
you don't have a global ip being assigned to your pc
