Some have the adapter, some don't.
To find out if the Ethernet adapter comes with a particular X1 Carbon 6th Gen model, look at the "Adapter" column in the PSREF http://psref.lenovo.com/Product/ThinkPad/ThinkPad_X1_Carbon_6th_Gen
Moderator note: fixed broken link.
For custom models configured in the online store, you get to choose at configuration time whether the adapter is included.
Hope that helps!
