Stats Result

File	Info
combined-stat	result of combining RIR's stats, the final delegated-extended stat
merged-stat	similar to above except that adjacent prefixes are merged
conflicts	overlaps found during today's/current run
overclaimed	resource claims outside what is delegated by IANA
unclaimed	unclaimed resources from what is delegated by IANA

Normal case

The following is diagram when there is no conflict detected, each of RIRs claims has no overlaps. There will be no alerts, conflicts, overclaimed and unclaimed files will be empty.

IANA pool will be calculated from subtracting the whole address space (/0) with combined claims from all RIRs + reserved spaces from IANA (IETF/IANA).

Conflict & Alerts

Conflicts/overlaps can happen between RIRs, or, between an RIR and reserved space from IANA files.

Conflict detection

In above example, results files will contain the following:

• conflicts file will report conflicting lines between RIPE and IANA (non-rirs/reserved), and between ARIN/APNIC
• unclaimed file will report resources allocated by IANA, but unclaimed by AFRINIC.
• overclaimed file will report resources over claimed by LACNIC

These conflicts will not automatically generate alerts. There is a grace period (2 days default) that will check if the conflicts persisted, only when the conflicts remains, we will send alert. In this example case it will be sent to RIPE, APNIC and AFRINIC.

Current implementation have not yet generate alerts for unclaimed/overclaimed.

RIRs involved in the conflicts will be informed.
