Private ASNs

http://datatracker.ietf.org/doc/draft-ietf-idr-as-private-reservation/

currently in the RFC editer queue expands the private ASN range by adding:

   "The end
   of the "32-bit Autonomous System Numbers" range will be reserved for
   Private Use, and a size of 94,967,295 (value to replace TBD1 below)
   corresponding to the range of 4200000000 (value to replace TBD2
   below) to 4294967294 (value to replace TBD3 below)."

This is over and above what exists today:

   IANA has reserved, for Private Use, a contiguous block of 1023
   Autonomous System numbers from the "16-bit Autonomous System Numbers"
   registry, namely 64512 - 65534 inclusive.

the documentation ranges are:




64496 - 64511 (16 bit) 
65536 - 65551 (32 bit)
