DNS suffix location guide? (HURRR IRC)

Is there any list or naming conventions for DNS suffixes of ISPs by location??

i.e.
nwnn.ga.charter.com (georgia, but whereish)
dsl.lsan02.sbcglobal.net (los angeles)
hsd1.va.comcast.net (virginia, but whereish?)

and what about like hr.hr.cox.net?

they all seem to have different standards and half of them make no sense. geolocation of IP's doesn't work most of the time either.

I know the hsd = high speed digital, and dsl= dick sucking lips, but other cryptic acronyms would help too.

also, cocks.

You're not supposed to be able to unambiguously locate IPs geographically. Quit trying to use a system for something to which it's very much unsuited.
