My dear GF - the internet is populated by many loud and inarticulate squeakers who scream "I haz ur IP I haxx you on HTTPS soz I brix ur FACEBOEK!"
They never fail to entertain
However, once upon a time FD
were guilty of delivering FQDN's to all and sundry - and that
was a problem.
Elite uses ports in a, well,
unique way, in that there is no restricted or expected range. It will quite happily open sockets to every port imaginable, go up and down that range in a single session, and sometimes alter those connections on the fly.
It's quite clever. It's also a bit of a nightmare. I can't really say much more without getting walloped - but anyone even half-way competent with networks will corroborate.
