Subject: About source IP address of IGMP Join sent on loopback interface

Hi,

I am running igmp daemon(igmp router side) and igmp host on same PC.
When the host joins on loopback interface, igmp daemon is expected to
receive the join report on loopback interface.
Here the join on loopback interface is not going outside the
PC(Outside Network).

Is it possible to receive join report (@ igmp daemon) with source IP
address as loopback interface address
in above explained setup?

When I run the host,  output of netstat command is as below:

#netstat -ng

IPv6/IPv4 Group Memberships

joined on loopback

eth0            1      239.5.5.6
eth0            1      239.5.5.7

Please cc me in the response
