In many cases, this data is so transient it has no audit value.

Smartphones, for example, seldom have ip assignments that last longer than
12 hours and are so unsticky they are likely to never have the same ip twice

Furthermore, folks who interface with arin && gear may only know a custimer
via a customer id or phone number.  The asociated personally identifiable
information (pii ) of such a subscriber may be in a protected data
warehouse that network folks dont have access too.

In fact, this name to ip address correlation business process may only be
in place for the purpose of lawful intercept under court issued warrant.

I believe arin is generally doing the right thing today.  But, clarifying
this process is prudent.  I am happy to provide gear configs and logs to
arin for justification, but pii is sacred ground.
