Thanks for all the answers! I think I have one more detail I'd like to know. Lets say you own X/22. You have delegated X/23 to your customer, keeping the other /23 for yourself. For some reason, your customer also owns and announced (to you) all remaining IPs necessary to complete X/21. Do you announce the aggregate X/21 (including addresses not associated with you), the aggregate X/22 (only address belonging to you), or the more specific route X/23 (including only addresses delegated from you to your customer)? Maybe I’m misreading this, but does the customer have LOA for the /21 aggregate? Thanks, Deepak
