[arin-ppml] Tax incentive for renumbering-related labor costs?

[Chris Grundemann]

Speaking as someone who managed a small ISP network (around 2000
customers) through several re-numberings of various scale, I will take
a shot.

For a single /24 (very rough estimates)
1) Design time; deciding what and how to do it.  ~5hrs (@ $75 - $100hr)
2) Configuration time; adding secondary IPs, redundant routes, etc to
prepare for the migration, adding NAT, port forwarding,  etc, and then
removing the old configs after the migration.  Assuming that the whole
/24 is broken all the way to /30s, ~10hrs (@ $75 - $100hr)
3) Notification and cooperation; working with customers (internal or
external) to set expectations and work through issues that arise.
Again assuming 64 distinct connections, ~10hrs (@ $50 - $75hr)
4) Opportunity cost (maybe I am using the wrong term); for an ISP,
there will likely be at least one customer lost, not sure how/if this
would translate to a campus setting.

$1125 - $1500 in Engineering cost
$500 - $750 in Customer Service cost
$1000 in Opportunity cost (mostly making this number up)

= $2625 - $3250

So call it $3k per /24.  Does this sound reasonable at all?
