Policy Statement on Address Space Allocations

Just to clarify this.....

We "originally" had a /20 and a /23 from Sprint.

Late July of Last year, we were out of addresses - we had more 
requests than we could fill.  I had attempted to obtain an /19 from 
Sprint, but was having difficulty getting the addresses.

As a result, I went to the internic.  After several rounds of "Why aren't 
you getting the address from sprint, and what's the deal with this and 
that", I finally got allocated a /19.  

About a week later someone in Sprint decided to allocate the /19.  After
the mess I had gone through, I decided to keep the second /19.

Sometime after I recieved the "two" /19's, Sprint announced that the 
filters would be applied at /18.  Great, now I have two blocks which I 
can't use on the net.  (Yes, I know, Sprint relaxed their filters, but 
after this was mostly done with).

Our goal was to renumber our customers into a announcements which we 
could guarantee would be routed when backbone router meltdown forced 
people to squeeze the swamp.   As a result, I needed an /18.

I sent a note to the internic, requesting an /18 in exchange for my 
existing /19's and the /23, which I would return to their origin 
registries. I got the following note back:

" The InterNIC allocates addresses to ISPs based on the slow start     
  procedure as detailed in the ISP guidelines.  Please utilize the /19,
  once you have reassigned the /19 and SWIPped them you may request    
  additional address space and if the InterNIC feels you are assigning 
  them efficiently you may request additional address space."

Which, in all fairness to the internic, I responded to with a very short 
note which summarized the application.  Basically, stating that I was 
unsure why that Allocating me an /18 in exchange for the equivalent of an 
/18 plus a /20, plus a few customer IP's, was a problem.

I got the block.  We vacated the /19's in a very short time, and we've 
about got the /20 vacated (2-3 /24's to go).

If I implied that the internic is forcing us to renumber, I'm sorry.  
What I should have said is "We're renumbering because of various 
reasons.  However, we had a hard time getting the /18 we're numbering 
into.  We succeeded in getting the /18 because we had over an /18's worth 
of addresses which we returned to the internic".
