The physical location is northeastern UK.  The geocoding you're 
referencing is incorrect.

As the links previously posted indicate, AOL has recently (late March / 
mid-April) implemented a policy of denying access to *all* residential 
DSL lines (so identified by the DSL service provider).  This is 
regardless of line history.  AOL has also started suing spammers, which 
I think is a strongly positive mood.  What I'd love to see them do is 
start teergrubing on a large scale.

Another ISP (redshift.com) throws up a periodic block on the address 
range in question, though it also generally tears it down after a while.

Aaron's comment was useful.  I returned the results of a quick search 
for DUL lookups, and didn't have other BL lookups handy.  The results he 
returned are similar to those I got when checking the IP earlier.

Todd's answer was marginally useful, but lazy in the extreme.  Two 
sources of information (the links referenced by me or the DUL referenced 
by him) could have told him what the IPs status as a dialup was.

Regards OT -- that was largely a reference to my communications with 
Brian.  Running Linux-based servers over various forms of networking and 
dealing with the fallout probably does count as on topic, so I'm 
changing my subject header.

Depending on the weather and my sleep deficit, I'm increasingly 
intolerant of crap posts to various mailing lists.  There's enough 
disinformation about tech, networking, Linux, and everything, without 
out us creating more of our own.  Engage brain before opening mouth (or 
interfacing keyboard).  That's all.

Peace.
