I've just recently realized something about the "lo" interface. You can bind a socket to any 127.0.0.N address, even though only 127.0.0.1/8 is configured in /etc/config/net, and "ip addr" only shows 127.0.0.1/8 for that interface. In the past, when I wanted to use other 127.0.0.N address, I always added them to /etc/config/net. The last time, I forget to do that. Later, I realized it was working anyway. I've since removed all of the extra "lo" addresses from /etc/config/net, and everything still works.
Apparently "lo" is special. Perhaps I don't even need to have 127.0.0.1/8 listed in /etc/config/net... -- Grant
