Good advice! :-)

Since you thanked VLH, I presume that filtering out a particular
posterÂ* _was_ your reason for wanting to find IP address(es). [It
would not haveÂ* occurred to me to use that method as I am aware that
a lot of ISPsÂ* reallocate from a limited pool.)

The "limited pool" as you term it, can be *3 million addresses*.
The addresses are *not contiguous* (some of the blocks were assets
in bankruptcy sales). The addresses can and are randomly
assigned, by the dynamic binding of ADSL sessions to terminating
equipment (backhaul) in a number of different Canadian cities.
Neither Geofencing nor IP numeric filtering would particularly be
surgical.

You want to block by ISP in such a case, not some numeric value. You'd

No, as I'd be blocking all users of that ISP. (Yes, there are semi-rogue
ISPs - ones where a large proportion of their customers deserve to be
blocked; but, even "respectable" ISPs have rogue customers they can't
easily disconnect, since rogue is subjective. You might just find a
particular user _irritating_, anyway, or just disagree with hir and
decide [as I did for one user on one 'group I take] that it'd be better
for all of the 'group if _I_ didn't see hir posts.)

get the IP, nslookup it, see what ISP, block the whole ISP. That way,
you "erase" the pool of 3 million non-contiguous addresses in one shot.
Where I live, that's roughly equivalent to blocking about half
my country.

How can I check if ANY of the people posting on the news.myplugbox.com
server newsgroups are using BT as their ISP?

I've always felt that Usenet is good - private servers? not so much!
