  As my footnote indicated I'm ex-HP (retired), so I couldn't tell.

  But many people say that there really isn't a lack of available
address space if people use NAT and IPv6 if and when they can. I'm not a
network specialist, so I can't tell if they talk sense or non-sense.

  Also I doubt if any organization/business is willing to *buy* Net 16.
After all, it cost HP a lot of money - like way, way too much :-) c.q.
:-( - so it's unlikely that they give it away.

  I think this is not a simple matter. Selling/buying a bunch of small
networks, i.e. Class B or C, is probably feasible, but a Class A

Noted up-thread, as of June 15, 2008, there were 2660804976 IPv4
addresses allocated/assigned by the five RIRs, and if you exclude
RFC3330 address space, that's 71.79% of "available" addresses. Looking
back to the end (12/31/xxxx) of the years, you see

1983       325151488     8.77%
1985       360680960     9.73%
1990       730298112    19.70%
1995      1374740706    37.09%
2000      1698877890    45.84%
2005      2246643418    60.61%
6/15/08   2660804976    71.79%

You mention NAT or IPv6. As an example, look at - a major
provider in the US. They have (at least) 45 IPv4 ranges totaling some
51.3 million addresses - the equivalent of a bit over 3 "Class A"
networks.  As many of those are used by residential customers, NAT may
be a good choice (look at the possibilities of improved security) but
is NAT likely?  I don't think so - it would break to many things used
by clueless users.  Comcast also has an IPv6 block - a /32 which is
79228162514264337593543950336 addresses (7.9e28) which should allow
every customer to have their own "Class A" and then some. Is that going
to happen soon?    Hah!

The shortage of IPv4 addresses has been hashed about for years. The
1994 edition of 'TCP/IP Illustrated Volume 1' by W. Richard Stevens
(ISBN 0-201-63346-9, a standard college textbook on the protocols)
mentions an article in the May 1993 issue of 'IEEE Network' (Volume
7 number 3) discussing the problem, and you should be able to find
copies of RFC1454 and RFC1475 via any search engine.

  1454 Comparison of Proposals for Next Version of IP. T. Dixon. May
       1993. (Format: TXT=35064 bytes) (Status: INFORMATIONAL)

  1475 TP/IX: The Next Internet. R. Ullmann. June 1993. (Format:
       TXT=77854 bytes) (Status: EXPERIMENTAL)

but what we know as IPv6 wasn't initially formalized until 1995

  1883 Internet Protocol, Version 6 (IPv6) Specification. S. Deering,
       R.  Hinden. December 1995. (Format: TXT=82089 bytes) (Obsoleted

and there are several other documents in that period.

I'm not sure, but believe that you don't *own* an IP range. You merely
have use of the range, and the "owner" remains the RIR - in this case
ARIN, who allocated/assigned it to some party. Certainly all of the
transactions I'm aware of are returning the block to the registrar who
may then hand it out to some other entity.

  1917 An Appeal to the Internet Community to Return Unused IP Networks
       (Prefixes) to the IANA. P. Nesser II. February 1996. (Format:
       TXT=23623 bytes) (Also BCP0004) (Status: BEST CURRENT PRACTICE)

RFC1917 is available via any search engine.  Problem is that you'd have
to convince HP to review their use.  Personally, I don't believe it's
going to happen - and that's not just HP, IBM, Xerox, Apple, MIT, Ford,
CSC, Halliburton, Eli Lily, Interop Show, Bell Northern, Prudential
Security, DuPont, Merck... you get the idea.  Over the years, a number
of /8s have been returned to IANA. Looking at the list beginning on
page 7 of RFC0990 (Assigned Numbers - November 1986) and comparing it
to the web page above might give some nostalgia.

The solution seems to be to go to IPv6. As of mid-month, there was only
a tiny fraction (0.00168%) of IPv6 land allocated/assigned, and the
_smallest_ block released is a /64 (18,446,744,073,709,551,616 addresses)
though /48s and /32s are more common, and IANA is even prepared for the
day when those addresses run out:

  1606 A Historical Perspective On The Usage Of IP Version 9. J. Onions.
       April 1 1994. (Format: TXT=8398 bytes) (Status: INFORMATIONAL)

RFC1606 is likewise available via any search engine.  Just looking at
the web page cited at the top of this post, I notice the "Former Class
E" address range ( is no longer marked Experimental, but
is "Reserved for Future Use". Given the fact that virtually every
network stack knows these addresses are special, I rather doubt that
anything will come of this change.

Closer to home there is no reason for HMG to hang on to 51/8, which I
believe is currently unused with the DSS and is not advertised to the rest
of the world via BGP.

"It's ours, you can't take it back, and we're not giving it back."  I 'spect
pretty much the position.  I'm sure HP finds having two class A address blocks
useful; whether other people need those addresses is no concern of theirs.
