OriginAS Information (Autonomous System Originations)
The implementation of policy 2006-3 (Section 3.5 "Autonomous System Originations" of the NRPM) tasked ARIN to do the following:
"ARIN will collect an optional field in all IPv4 and IPv6 address block transactions (allocation and assignment requests, reallocation and reassignment actions, transfer and experimental requests). This additional field will be used to record a list of the ASes that the user permits to originate address prefixes within the address block."
The policy also tasked ARIN to make the collected information available. OriginAS information is available at the ARIN ftp site at: ftp://ftp.arin.net/pub/originAS/
