IGMP SNOOPING QUERIER Question

Can someone please explain how this address became our igmp snooping querier?

sh ip igmp snooping querier
Vlan      IP Address               IGMP Version   Port
-------------------------------------------------------------
1         10.49.4.100              v3            Gi8/0/47

I never intentially set a querier yet this is the address that comes up when I do the show command.

This device happens to be a firewall connected to our switch stack. It is not a cisco asa or router. it is a windows server.

All that is saying is that the switch has detected an IGMP querier on that interface ie. it is seeing IGMP queries arriving on that port. So it looks like the windows server is sending IGMP queries. If it is you don't need to configure this on the switch, the switch will automatically detect it.
