Try natnum form the IASON tools. $ natnum echnaton.serveftp.com host_look("84.167.246.104","echnaton.serveftp.com","1420293736"). host_name("84.167.246.104","p54A7F668.dip.t-dialin.net"). You can feed natnum a hostname or an ip-address or even a long integer. If you want to dump an address range use name2pl. $ name2pl 84.167.246.100 8 host_name("84.167.246.100","p54A7F664.dip.t-dialin.net"). host_name("84.167.246.101","p54A7F665.dip.t-dialin.net"). ... host_name("84.167.246.106","p54A7F66A.dip.t-dialin.net"). host_name("84.167.246.107","p54A7F66B.dip.t-dialin.net"). Dumps you 8 ip-addresses starting from 84.167.246.100.

None of these will be foolproof and the last one will probably only be good for cases where there is a service running where'd you'd rather there not be and you can test for it (e.g. open relays). There was at least one additional reference to related work in that paper, which leads to more still, but I'll let those interested to do their own research on additional ideas for themselves.also note that we are using TCP fingerprinting in our spamtraps and expect to have some interesting results published in the august/sept time frame.
