Still that doesn't give any reason to provide /112 for point to point connectivitiy. Seriously, I'm peering with a transit provider with /126 and when I asked for a reason they said, ease of management. How come Subnetting /32 to /126 is ease of management??.... thats quite difficult to understand. This debate is there fore quite a long time but everytime it pops up I feel so uncomfortable with this granular subnetting.
Some networks prefer a uniform numbering scheme. /112 allows for reasonable addressing needs on a circuit. In addition, while Ethernet is often used in a point-to-point access circuit, such layouts may change and renumbering would be annoying. Finally, having chunks 4-7 define the circuit and chunk 8 provide the circuit addressing makes it more human readable and is prone to less mistakes by those who suck at math. Jack
