Change integer base to hex for fields representing addresses

Change integer base to hex for fields representing addresses

It seems more expected to show addresses in hexadecimal.

I applied this to all fields named "ip" or "addr".

I haven't change the `addr` fields in the i2c.h file as I am not aware
of what is the convention when displaying I2C addresses.
