They are both right. If you have a dynamic IP such as most college students
have, it is here-today-gone-tomorrow.

If you have static IP (business, us slugs in the Swamp, etc) you are identifyable.

Hi Lou,

Long time.

The thing is this isn't an atemporal question. The association of an address and any other information that tends
to identify an individual (say my googling the complete works of the co-author of "Survey of Modern Algebra",
along with Saunders MacLaine, in particular reference [1], the "original" treatise on shaped charges, and my
groveling for clue in DNS ops, and my ...) tends to unique closure over finite time.

So, for a single datagram sourced from a just-allocated at random DHCP pool, wicked hard to make PII.
But for many hours or days of stream to a variety of data collectors, some of which share raw or correlated data,
the problem is not insoluable.
