The example for using wget to retrieve json uses jsonip.com, which when you look at what it returns, returns some political crap with "reject-facism":"random bullshit"
I would use a different example.
Wow, didnt even noticed that, any alternatives to suggest? That is pretty fast
At first the one I found was jsonip.org because it was advertised as an alternative to jsonip.com
Well it's just as politicized so I don't know what they were thinking.
I found this however: https://api.ipify.org/?format=json
