This site is linked to other sites that also provide coverage to multiple counties, often overlapping. When designing the sites' coverage, we made no attempt to limit it to particular counties. Any allocation by county would not match the needs of this IP network. To build this large logical network, we started with a /20 allocation. Had our region been divided evenly by county before we requested this allocation, there would not have been a large enough block remaining to assign! I have seen an instance where a 44net region was subdivided into counties, most with no users. Those counties that had users often had only one or two, so there were many small allocations scattered around the region's /16. A request for a new large network came in and the coordinator had to reject it because he had left no contiguous space large enough for this network. This was poor planning. (I've intentionally left out the region's name to avoid embarrassing the coordinator.) Political boundaries rarely match network boundaries. Tom KD7LXL
