You are right about that. According to my pop logs, my servers have encounter about 1000 different IPs from google (920 actually). 
Domain names are always like mail-[a-z][a-z][0-9]-[a-z][0-9][0-9]*.google.com
By the way, I'm in europe, I'm not sure USA, Australia or Japan would see the same gmail POP clients.
