It is similar to my feelings on charities, I take care of my immediate families needs first, then I look to extended family (brothers, cousins, inlaws), then I look to charities in my local community, then I look to charities in my state, then I look to charities I am involved in. If After all that I find I have money left over I don't know what to do with I will consider donating to far off charites.

So, you are saying "charity begins a home."  Great, but there is another 
saying that needs to be considered too, "to whom much is given, much is 

If you look at the distribution of IPv4 since the creation of the RIR's 
it is more or less reasonable and fair.

APNIC - 45 /8s
ARIN   -  36 /8s
AfriNIC - 5 /8s
LACNIC - 9 /8s
RIPE   - 35 /8s

However, there are 91 /8s that are part of the central registry 
(Legacy), of those the equivalent of about 7.5 /8s of bit and pieces 
were given out to the RIR for distribution.  The vast majority of the 
rest are allocated to organizations within the ARIN region.

32 of the 91 are original Class A networks (whole /8s) given to 
individual organizations within the ARIN region, there were more but in 
the past few years a number of organizations returned legacy Class As 
(Thank You by the way). There are 4 Class As that went to organizations 
outside of the ARIN region, I think all in RIPE.  That leaves about 47.5 
/8s that were used for Class Bs and Cs, again the vast majority were 
allocated to organizations within the ARIN region.

I'd love to see an official breakdown of the central registry space by 
region, but I'd be willing to bet that at least an equilivant of 75 of 
the 91 /8s were allocated to organizations within the ARIN region.  So 
by my count the ARIN regions has at least 111 of the 221 /8s that were 
available.  Even if my numbers aren't completely right, it is clear that 
the ARIN region has at least twice as much as APNIC or RIPE and as much 
as 10 times LACNIC and 20 times AfriNIC.  It doesn't seem reasonable to 
me that we now take an attitude that if it was allocated to our region, 
it therefore must stay in our region.

To conclude the ARIN region has as much or more address space than the 
rest of the world combined.  Part of that is natural, the Internet 
started in what is now the ARIN region, but it seems wrong to say what 
is in our region stays in our region when our region has been given so 
much.  If you also include that most of the growth of the Internet is 
and will continue to be outside our region then it is doubly wrong, and 
just adds insult to injury.
