I noticed the other day that my Android phone (Moto X first gen running lollipop) was reporting having an IPv6 address.
After a bit of investigation I discovered two things
- It only shows when connected to WiFi, not cellular data.
- The address it is showing is a loop back address starting
I am a bit bemused as to why this is. Why would it be enabling IPv6 and why would it be reporting it's address is a loop back address?
