It's useless, my first basic test is failed. Don't use it!

Worse than useless, because it fails valid addresses and passes invalid ones.
192.168.0.4 - which was on my home network for a while - should work, but doesn't.

Of limited usefulness, since it fails 1.2.3.4 and allows 111.222.333.444

I cannot say that I agree with you. Why do you say that it won't "catch" (I presume that you mean match) 172.616.21.30? I think that it does. By saying that I do not mean that this is a great pattern - it isn't!
It is basically saying, match this:
([0-2]*[0-9]+[0-9]+)
... 3 times. The first part - [0-2]* - states that the first digit is optional while the next two character entities tell us that there can be anywhere between 1 and positive infinity digits; twice! Therefore, based on this pattern the following input would validate without problem:
99.999999999999.99.999999999
I'm sorry but I rated this pattern a "2".
