To find the IP's of a loopback interface you can log in to it and run several different commands.
show ip interface brief
sh ip int brie
-This will give you all the interfaces on the router that are configured along with their IP address if set and their status, up/down
show running-config
sh ru
-This will give you a line by line visual of the entire contents configured in the router. This will take more disecting but you will find the info you are looking for this way too.
show interface
sh int
-This will give more detailed information about all interfaces on the router. You will need to disect the output to find the info you need here as well.
For the quick snapshot use the sh ip int bri command
