Oui,je pense que ne pas bloquer cette requête n'est pas aussi nocive que ça.
Mais..........J'ai receuilli cette discussion sur le Net ;et il y a une chance que ce soit un programme genre spyware qui veut communiquer avec sa source.

Your computer is set up to accept "IP Multicast". This is a setting in
your OS and does not depend on whether you view streaming media or
not.
Mcast.net is not a real domain; it is the fictitious domain set up for
the IP addresses that are reserved for IP multicast.
Nothing to worry about.

This means that some software on your machine is pinging
64.224.86.159. My guess is that it's some software trying to tell if
you have an active Internet connection or not, probably so it can
phone home and check for updates.

It's still possible that some program on your machine is making the
network connections without asking you. But the only way to be sure is
to reinstall Windows...

Je vais quand même voir si avec spybot il n'y a pas de spyware trop nuisible.
Merçi bien
