I needed to look for the allocation of the IP address 66.179.240.29 and found out the owner. This was an IP address under allocation of ARIN. Obviously, I would use the web site of www.arin.net and doing a web-based whois search. Quite strange, the information could not be found.
Intutively, I had the feeling that web-based whois search is not as reliable as whois client directing interacting with the whois database of ARIN. On a Unix shell, the command to be invoke is :
$whois 66.179.240.29 whois.arin.net
[Querying whois.arin.net]
[whois.arin.net]
Inflow Inc. NFLO-AR-3 (NET-66-179-0-0-1)
66.179.0.0 - 66.179.255.255
PBase.com, LLC INFLOW-996-94320-16484 (NET-66-179-240-0-1)
66.179.240.0 - 66.179.240.127

Yes, really. It worked which indicated web-based whois could not provide reliable information.
