We have found that 628,000 IP addresses, or 23% of IPs that have accessed our site in the last two months, do not resolve to a domain in the Domain report. This is despite the fact that the first 20 no-domain IPs we tested are listed in APNIC and commercial databases like IP2Location with a domain.
Additionally, domain is only so useful, as it's often the ISP's domain and not the registering organization. We're looking into using a third party data source to bring this information in, but surely other Adobe customers want to know which companies and organizations are visiting their sites. Is there any chance of integrating with one of these databases to provide whois organization?
