I'm attempting to convince "the powers that be" that attempting to use reverse lookups to determine geographic locale is extremely inaccurate. One of the reasons among the many this is the case (I believe) is that significant portion of admins do not have properly configured in-addr. Has anyone done this sort of survey(Bill Manning?) If so, anyone have a pointer handy? Thanks.
Define "proper" please. Depending on what the selection criteria are and where one is looking, the numbers vary. The Mice&Men numbers indicate upwords of 75% of the delegations are flawed. My numbers point to about 55-60% of the delegations have some errors. On a bad day, I'm surprised the thing works as well as it does. -bill
