Calibre server showing incorrect ip address

[crouton]

Hello
Long time Calibre user and never encountered this problem before. Previously when running a content server the app would specify my ip address:8080 on the connect/share drop down.

Now it's only showing localhost 127.0.0.1:8080 instead of my actual ip. However going to the ip itself at port 8080 still shows my library.

Has anyone else run into this? Any ideas how to fix it? I'd like the correct ip to show up as it used to.
I'm running 2.47 on El Capitan 10.11.2

Thanks

ETA In preferences>Tweaks it shows correctly as

# What interfaces should the content server listen on

server_listen_on = '0.0.0.0'

Which i've never changed, so why would it change all of a sudden?

The IP address is simply a guess at what interface on your computer corresponds to the externally visible one. There is no robust way for calibre to know what your "computer IP address is". That guess can change depending on the way your networking is setup. It does not harm anything, since that information is provided just as a guide for people to know what to type into the address bar of browsers connecting to the calibre server.

Thanks for the response. I didn't change anything on the computer and one day the Calibre just changed from showing my ip to showing just generic home ip. That's why I was confused. Don't know what triggered the change.
