14. Will you announce only the single, aggregated IPv6 prefix you

14. Specify YES or NO. If you receive an allocation from ARIN
and you will only announce the least specific, aggregated
prefix to your BGP neighbors, indicate YES. If you plan to
announce more specifics of your allocation to your BGP
neighbors, indicate NO.
I said yes when applying for our /32. The instructions imply that no is a
