ACSP Suggestion 2025.5: Show Reassigned Prefix Block on Main Page
Suggestion

Description: show reassigned prefix block on the main page
Value to Community:
I created RPKI ROA for a /22 not knowing this block had been re-assigned to another entity of my company, it resulted in losing (90%) of this route/prefix on the internet.
it’s operator error on my side. After replay of the incident and trouble-shooting process, I think a little change on the resource main page could’ve helped me to avoid this problem -
- this /22 prefix was RPKI unknown
- I checked my network address allocation and the whole /16 belongs to us
- I DID NOT check the BGP routing table
- I DID NOT check the details (the + sign) of the /16
- I created the ROA with my own AS
Is it possible to bring the reassignment information to the main page? if so, I could be alerted earlier.
