However, we’re talking about relatively large numbers of customers for relatively small numbers of IPv4 addresses that aren’t producing revenue directly at this time anyway. > Even with $1/IPv4/month - what will be the ROI of a brand new home router? About 2.5 years at that price since a brand new home router is about $29. Owen
