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.
