How comes?  Is it because a starlink box might have that printed on a 
label?  Or the user manual?  Or the FCC application?

What reflects the entire Starlink specification?

Interesting.  It is an optics specification.  Also kepler refers to the 
same document.

If starlink uses that optical system for ISL then it is worth noting.

Remark also that that spec tells there is Ethernet in there.  It might 
be that because of that IP might be used.
