The default is 2^8(256). However, it can be changed by doing, for example
$ns set-address 7 24 (not sure this is the right syntax, please refer to
tcl/lib/ns-address.tcl
This extends the number of ports to 2^24, but the number of nodes allowed
is shrunk to 2^7. You'll have to be extra careful if you're doing
mcast simulation.
As for max number of TCP connections, the default will be 2^8.

Sorry, I don't quite sure what do you mean by 'fan-in' and 'fan-out'.
hope this helps.
