Comment (by smarquilly at acipia.fr):

 Can anybody remove my email address from the description and the "reported
 by" sections ?
 I didn't know that this ticket would be published and browsed by search
 engines.
 My email receive spam now ...

 Thanks for your help

 > Hello,
 >
 > We use pulseaudio in our LAN and we've noticed that the default
 Multicast IP Address (ie 224.0.0.56) used by the module-rtp-send and
 module-rtp-recv seems to be part of the "well-known" Multicast adresses.
 As a result, some switches (HP Procurve in our case) won't filter the igmp
 traffic, but will broadcast it to all ports. I attached a documentation
 from HP Procurve Networking with better explanations about this on page
 100, (4-22).

 > We had to change the multicast IP address to resolv that issue. It seems
 that the 239.255.x.x range is dedicated to local multicast diffusion. We
 use 239.255.1.56 and it now works perfectly. My request is to have the
 default multicast IP address changed so that multicast diffusion works in
 all case with all network materials.
