I'll have to check my research notes if I have them but I had found a SHODAN server in the 66.240.236.0/24 range. It was all cloud hosting so I blocked them all but there is a SHODAN server in there somewhre.

shodoan uses shodan.io hostnames, you can check by a ptr scan of the subnet and there is one host in it:

66.240.236.119 census6.shodan.io

Just an FYI, the list of Shodan.io servers represented here is incomplete.

Here is the list I had compiled (yes, some are PTR-only records, and that is not listed here) based on this: https://wiki.ipfire.org/configuration/firewall/blockshodan
