There’s at least one vendor *cough* cisco *cough* that has used it as
captive portal IP.

I’m not sure I would try to use it on a client machine because you don’t
know if you’ll reach the internet.

If you know you’re not on a closed network, you could use it instead of
the list of usual suspects, like 8.8.8.8 4.2.2.1 9.9.9.9 etc.
