Yes. I give my justifications for doing so in this commit: https://github.com/jpf/domain-profiler/commit/b00aba5d6410210b5cfb0f25387254fa475163ce https://github

IHMO, yes.

Please split them out. What many people here are looking for is a snapshot of the choices a group of smart people have made : Going to rackspace.com is a whole different choice than heading over to slicehost.com.

  Makes sense. I'll do that after I'm done with the meeting I'm in now. Edit: Changed. However, the number of companies with A records in netblocks that are owned by "Slicehost" is pretty small. Perhaps Rackspace has been working on changing the names on the Slicehost netblocks?

    No: http://whois.arin.net/rest/nets;q=173.203.218.200?showDetails=true&showARIN=false http://whois.arin.net/rest/nets;q=173.203.218.200?showDetail... That's embed.ly - they're at Slicehost, but you still have them at Rackspace even after this change. Your script might be confused because the /24 is a reassigned child of Rackspace's /16. I've parsed WHOIS in the past and the corner cases make a very solid argument for just doing it by hand. IP ownership issues, which you've already seen with Linode, make it almost exclusively a wet code problem. There's a few nagging questions with the list from a casual skim, too, one of them being octopart.com - 64.71.142.178 is part of a reassigned /28 out of a Hurricane /18, which means Octopart likely hosts themselves. I have doubts you get a /28 from Hurricane with their shared hosting, but their sales page does list a static address (singular). Shrug.

      Most of the mistakes were due to my script using Team Cymru's IP to ASN mapping service (http://www.team-cymru.org/Services/ip-to-asn.html http://www.team-cymru.org/Services/ip-to-asn.html) thanks for your tip on using ARIN's Whois service. Looks like I've got more accurate results with them.

        Yeah, you'll get announcing datacenters out of that, but for IP ownership, you need to check WHOIS. ARIN WHOIS is only going to be ARIN regions (the Americas) - you want RIPE for Europe, APNIC for Asia/Australia, and so on.
