Could you clarify that? Because that part of the question doesn't make sense. >From an IP address, you could lookup a PTR record ... which will generally get >you the name of the ISP that owns the IP address. Unless it's a server where >some admin carefully set the PTR to match something specific, generally for >the purpose of operating a DNS or SMTP server. If the IP address belongs to a >server, then you could conceivably get WHOIS for that domain. But aside from >that ... Sounds like you want to lookup WHOIS for 1m US users, where 999,000 of them will be Comcast, Time Warner, AT&T, Verizon, Earthlink ... That's a whole lot of repeat queries. Maybe you're not actually trying to lookup IP addresses. Maybe you mean you want WHOIS for 1m US domain names? And godaddy doesn't like the flood of WHOIS queries? For that ... I say ...

You're not the first to think of that. Trust me, all of Amazon's IP addresses are already blacklisted. I already tried using them to cover temporary outages of mail delivery. It's only possible if you first get a static elastic IP, then put in lots of effort to get its reputation cleared, and then maintain it diligently. _______________________________________________ Tech mailing list Tech@lists.lopsa.org https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
