Good day,

No – you must use a unique customer identifier for each simple reassignment.

We moved from performing detailed-assignment (ORG+POC) to just SIMPLE ASSIGNMENT.  We had many old records that where once set up with DETAILED that are now trying to do SIMPLE ASSIGNMENT. In the old way we always re-used ORG-ID or HANDLE that we got back from ARIN for all subsequent registrations involving the same customer. So suppose we have the following:


when we do the first simple assignment for IP-A we obtain Customer handle Cxxxxxxx. The question is can we use the same customer handle for IP-B (same customer information) or must we obtain a new Customer handle for each IP when doing Simple assignment?
the answer was not clear to me from the web site.
