A couple of bits will allow that.I didn't claim 8 bit average (if I accidentally did, my apologies). I claimed a minimum of 8 bits. Somewhere between 12 and 16 is more likely. However, with new ARIN proposals, we will see shorter shifts (yet still over 8 bit shifts) as it does nibble allocations for everything (pop assignments nibble aligned, ISP allocations nibble aligned, ISP to ISP reallocation policies). It treats utilization as a 75% bar with nibble alignments to allow for proper growth at the ISP level.
Why would a pop need to be nibble aligned? Customers should be nibble aligned as it requires a delegation in the DNS. A pop doesn't need a delegation in the DNS. Mark -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka () isc org
