colloquial use in Usenet is a problem, because you are writing for
people who may not even have this language as primary or even secondary
use. "Technical English" is bad enough before you start bringing in
terms like "the computer is wedged".... huh? ;-)

What was the address? If an authoritative whois server (for IP addresses,
that would be the ones from AFRINIC, APNIC, ARIN, LACNIS and RIPE) says
the address is reserved, you shouldn't be seeing it. On the other hand,
there are a number of whois services (geektools.com and samspade.org being
but two) who may be providing answers from their cache/records/what-ever,
and those must be taken with some caution. Also, you need to watch the
wording used - RFC3330 lists a number of "Special-Use IPv4 Addresses"
such as 10.0.0.0/8, which some might call "reserved for private use",
although that isn't the official terminology.
While whois servers should not make mistakes about reserved address space,
it's not unheard of for typos to occur. When AFRINIC started last year,
for two weeks the zone files (but not a whois query response) was
announcing a 10.0.1.1xx address range as being assigned to Uganda. In
similar fashion, RIPE was reporting a host address, rather than an entire
network because they fumble-fingered the network mask value on a database
entry used by the whois server (but this was not wrong in the zone file).
That was also corrected relatively quickly.
It's not impossible for something fishy to be happening. Whois data is
after all, just registration information. There have on several occasions
been cases of IP hijacking, where some system starts sending out incorrect
routing information to the Internet at large. This is usually detected
and corrective action taken in a relatively short period, but it's
certainly not unknown.
