Netstat -g where the group IP is defined
Hi when I run netstat -g I see the following table. However, I just don't know which IP address all-system.mcast.net is mapped to? Where is it defined? Is there a file in linux to configure it? Thanking you in advance

"all-systems.mcast.net" and similar addresses are reserved for IP multicast and are registered with the IANA. They cannot be changed.
In your case all-systems.mcast.net is 224.0.0.1.
