| I've been trying, without any luck, to determine whether or an IP address is contained within (a list of) subnet(s). The computer assets table contains subnet information, cidr type with /32 for individual hosts, as one would expect. I'm selecting the IP of hosts that fit certain criteria, but also want to exclude those hosts if they are contained in one of my subnets: select a.ip, b.foo from tablea a, tableb, b where a.id=b.id and a.ip ! <<= (select network from assets where network is not null) 1. "! <<=" doesn't seem to be valid 2. the subquery returns more than one row 3. I'm not getting anywhere trying to write a function to take the ip and loop through all the subnets using the "<<=" operator and, I guess, & all the boolean results to determine t or f. Has anyone run into such a problem? Any suggestions?
