[AFRINIC-rpd] Academic IPv4 Allocation Policy Second Draft (AFPUB-2013-GEN-001-DRAFT-02)

[Mark Elkins]

Lets look at a non university example.

IGF Baku.

Attendance was above that expected - around 1500 to 2000 people.
On the pre-opening day, there were however only 500 people- and the WIFI
worked fine.

I think the organisers banked on about 1000 people - and they had a /22
available.

This they eventually changed to a /21.

There were still problems.

I had both a Laptop, Cell phone and iPad with me. My cell phone has
WhatsApp on it. I do roam but International Data roaming is very
expensive, so I just allow my phone to use the local Wifi. (Even at
home, I keep the Wifi on, software updates can really eat into a 3G data
bundle).
Whilst in meetings, I usually use my Laptop, but the Apple iPad is on
(despite the screen being blank - etc). So most of the time I am using
three IP addresses. I don't consider myself to be particularly unusual.
For example, so many people have more than one cell phone.

I'd consider allowing a University to state what ratio they'd like to
use. (1:1, 3:1, 5:1) - but for now nothing higher than 5:1 unless they
can provide additional justification. I'd be surprised if universities
did not go for a higher ratio, they may pay more though - and I do
believe that the future is multiple devices.

I wouldn't worry about a non-utilisation problem - unless we suddenly
here of that University trying to sell unused IP's.
