    h="$1"
    echo curl "https://blockchain.info/tx/${h}?format=json" |

Find missing hits in IP ranges Updated +Created
All IP ranges have some holes in them for which we don't have a domain name.
It is because there was nothing there, or just because we don't have a good enough reverse IP database?
It is possible that DomainTools could help with a more complete database, but its access is extremely expensive and out of reach at the moment.
Censys is another option that would be good to try.
