Fair point. However, considering more and more outfits block content
based on IP geolocation, once has to wonder if an outfit such as the FTC
could mandate certain standards and disclosure of inaccuracy of IP

Or the other way around (shudded) mandate that outfits such as ARIN
ensure IP blocks are accurately configured/registered to provide
accurate geolocation within state/province for instance.

By documenting that IP blocks only resolve to state/province, this would
set the implicit standard that any IP geolocation service that claims
more precise gelocation is bogus.

And mandating IP blocks be limited to state/province would be a big
enough headache-causing undertaking as large number of ISPs and
organisations span this and want to have abilityto move blocks around to
cope with demand increasing more in one state than the other etc.

So that leaves ARIN mandating and documenting that IP blocks be
accurately registered on a country basis within its territory. This
would allow proper geolocation/blocking for outfits like Netflix but be
documented as being unusable to track an IP down to state, city,

When ARIN makes IP block database available for download, it should have
an "agree" button to terms and conditions that would prevent the user of
the data from claiming accuracy greater than "countrty".

Just an idea.
