Hi,
I know that IP addresses in the USA follow a strict pattern of
geographical
locations. (Most other countries don't do that.) Does anyone know where I can get a copy of the table of IP addresses vs. city names?
Whomever told you this was wrong.
No Bill. You are the one that is wrong. :) regards, Hung Jung _____________________________________________________________________________________ Get more from the Web. FREE MSN Explorer download : http://explorer.msn.com

Actually Hung, on this one he is right. I owned and operated an internet service provider for four years. There is no 'strict' policy of who gets what address block. Random companies in random cities at random times ask for, and recieve, random chunks of classless address space based on their need. It is true that this chunk of address space is then _usually_ assigned to only one geographic location, but there is no strict policy and no one keeps track of it in a big-brother database 'table' that maps this information for you. The companies themselves may keep track of which addresses go where, but they are not required to report this to anyone or to update some global directory when they change their network setup or move stuff around. Also, at the highest level are large organizations, phone companies, universities, government organizations, etc. In the case of companies, these organizations usually get a huge chunk of address space and them sell it off to other people, like, for example, GTE (a phone company) sells its addresses to Genuity (an ISP) which sells its addresses to Nap.net (an ISP) which sells its addresses to Collective Intelligence (the ISP I used to own) which sells its addresses to Dialogue, Inc. (an ISP owned by my buddy Adam). Adam was not require to report to me what or where or who he sold his addresses to, similarly I was not required to report that informtaion to Nap.net, who, in turn I presume, is not required to report the information on upward and so on. At the very highest level, the only information know is "GTE owns 200.x.x.x to 220.x.x.x". GTE is, geographicaly, the biggest phone company in the US, serving almost all of the rural mid-west. That said, there is a company that has intrusivly scanned the whole internet (globally, not just the US) and claims to have, using deduction, figured out where all the addresses are. I'm assuming their service is very expensive, not 100% accurate (because neworks move and get rewired) and it is targeted towards advertisers: http://slashdot.org/yro/00/11/06/0521235.shtml -Michel

There are a few companies out there which try to provide that service. Check out www.visualroute.com , it's not too expensive and sorta accurate. In any event, what Michel said applies, there is no geographic IP map, although the initial assignment of IP space tried to do that (check out the old forms from nic.ddn.mil, which was in charge of assigning numbers before arin). -Th

On another tangent there is an interesting RFC (1876) that documents an extension to the DNS record to include geographical information. Not useful for what you are looking for (as it probably isn't widely implemented and is subject to error in event of movement of the server) but for a company managed network it would be pretty nifty! ftp://ftp.rfc-editor.org/in-notes/rfc1876.txt Cymen Vig cvig@raw-io.com

<modesty value="0"> There is even <a href="http://www.internatif.org/bortzmeyer/query-loc/">one implementation for the client</a> (for the server, it is already in BIND). </modesty>
Even if true, how would that be useful if ISPs are assigning IPs from their servers to clients all over the country. Now you know where the ISP's servers are. Even static dsl IPs come from the ISP's lot. ----- Original Message ----- From: "Hung Jung Lu" <hungjunglu@hotmail.com> To: <bill@noreboots.com> Cc: <zope@zope.org> Sent: Saturday, December 02, 2000 11:27 AM Subject: Re: [Zope] IP address and US city name
