Indeed. dhcp musical chairs.

Its vanishingly unlikely that a person who gets your ip address just
vacated will be posting to the same newsgroup, but if you are both in
the same geographical area its entirely possible

But a much more likely thing is that the ISP is using an 'invisible'
proxy. That is all request for port 80 traffic irrespective of actual
final destination are vectored to their proxy.

When all your customers tend to watch the same porn, this saves a lot of
upstream bandwidth, and its a great way to create 'walled gardens' where
only YOUR porn is allowed.

if the ISP was AOL I would say its a virtual certainty, but its unusual
to proxy nntp traffic. But it might as the poster above say, be NATTED.


Certainly pretty much all of some mobile operators IP addresses are
NATTED in some way.


Its nasty because you cant then accept incoming request bit there you go.

Probably the smart phones don't have any server capability anway.

Ineptocracy

(in-ep-toc’-ra-cy) – a system of government where the least capable to
lead are elected by the least capable of producing, and where the
members of society least likely to sustain themselves or succeed, are
rewarded with goods and services paid for by the confiscated wealth of a
diminishing number of producers.
