Gordan:

On Thursday 12/28 you enclosed with the text below:

To help you understand the PRDB, I offer some historical
information from an engineer's perspective: 

  The concepts and the some of the code for the PRDB database system
  predate even ANS's creation.  The PRDB concepts come from
  the early days of the NSFNET and trying to run that specific network.
  The multiple ISP/NSP world has come upon the Internet to replace
  the NSFNET.  This change was requested by some people to provide
  a fair marketplace in the Internet.

  The routing registration shift from PRDB to RIPE/IRR
  format reflects a shift in the Internet reality, not an
  ANS database specific project.  The effort to keep the NSFNET
  service current was an engineering effort over years.
  We moved from 1/3 T1 to T1 to T3.  Our databases also migrated
  implementations and service capabilities.  The PRDB was the
  third in a series of the databases.  RIPE could be considered
  the fourth.   

I hope this has helped fill in some history around Curtis's comments.
