Dear All,
#6. <DNS, IP Address> mapping in Holistic Context--
Not exactly sure what this means. I've already mapped the gTLD websites down to individual web hosting providers and by country and gTLDs. Currently, 1.59% of gTLD web hosting providers are pending classification and many of those are websites by ISP customers using their broadband connections to host websites. The resolution for the US web hosting provider market is 99.35%. It is an expensive and time-consuming process to identify and group web hosting providers because some of the connections are often non-intuitive. I haven't published this data yet and don't know how to price it. Hong Kong has over 5 million gTLD websites and many are not hosted on officially allocated Hong Kong IP addresses. The IP addresses have been leased via brokers. China hosts many of its websites on US flagged IP addresses due to the shortage of IPv4 addresses. The hosting geography of some countries follows linguistic patterns in that they host externally in countries that use the same languages. Some countries have well developed web hosting industries and no ICANN accredited registrars. (It gets back to the argument about ICANN's registrar model being a great idea for the 1990s.) As of this morning, approximately 7,646 distinct web hosting providers (as distinct from domain hosters) account for 98.41% of the gTLD Web. At a domain hosting level, some large registrars provide DNS service for thousands of web hosting providers who do not run their own DNS. Some countries have minimal gTLD website footprints. The local web hosting infrastructure just isn't there. Some small countries are almost completely reliant on ISPs (often the main telcos) hosting and have very small local web hosting industries. Their web hosting industry is often using web hosters in other countries. Cloud hosting is much more complex than claiming that the main Cloud hosting providers account for n % of the market. The gTLD webscape, at an IP level, is complex. Throw in content delivery networks (CDNs) and it gets even more complex. Some countries are regional superpowers (Turkey, South Africa, Singapore etc) in terms of web hosting. Othre have less than 100 websites hosted. There is also an important overlap with DNS Abuse and the naive expectation that all parties in the chain of hosting for a website can be reliably identified with WHOIS checks. To put it diplomatically, abject mangling of WHOIS for domain names has made the Web less safe. While there were some good reasons (spammers, customers being poached etc) for redacting some data, some registrars took the opportunity to redact everything. RDAP may not fix that problem. Many IP addresses have no abuse e-mail contact listed. At an IPv4 level, addresses are leased and brokered regularly to such an extent that a business has grown up around it.
