Perhaps this explains > the explosive growth in the routing tables since ARIN took over. Well, the /20 is merely part of the initial allocation guidelines of ARIN. Yes, moving the smattering of other blocks into the /20, returning those to whichever provider from whence they came. Renumbering as much of the original /20 as possible, and then requesting additional space. In my experience, at having renumbered about a /17 of PA space into PI space, the process is fairly painless outside of customer interaction. You find areas of inefficiency that can be cleaned up, allowing you to fit more into a smaller space (renumber /30s into /31s, gee that lan with 3 boxes doesn't need a /24). You keep records of what you've done, and provide them in future allocation requests. On the whole, dealing with ARIN was pretty painless. His error was that he expected that ARIN would just give him more space than what he had in PA space. This would just be silly of ARIN for several reasons: 1) Many companies provide address space based upon policies other than justified use, such as based upon circuit size. 2) Many initial allocations are used very inefficiently, with lots of holes, networks larger than needed, etc.
