Yes. X11 can be used over TCP and over Unix Domain Sockets. Unix Domain Sockets
is emulated in cygwin with TCP. So X11 in cygwin does always use TCP. 

You might have noticed that xterm connects to a 127.0.0.0 address which is a
local only address. The xserver connects to IN_ADDR_ANY and not to a specific 
network interface. 

All network traffic (except the DNS query) is only local.
