Just had a visit from scoutjet on a new (to me) IP range...
199.87.248.0/21 (199.87.248.0 - 199.87.255.255)
rDNS: hhh.scoutjet.com
That's three ranges I now have (had) for blekko's scoutjet...
38.99.96.0/24 - still rDNS of scoutjet
64.13.159.0/24 now seems to be abandoned by blekko (ie no rDNS)
I haven't seen anything from scoutjet this month until the new one. The new range looks much more impressive so maybe the other /24 will soon be discontinued.
