I thought this was an interesting message about the size of allocation 
that University of New Hampshire received, a /32, and the justification 
behind it.

Wikipedia tells me they have ~15000 students and 600 "admin" staff.  Their 
web page says 600 f/t and 400 p/t faculty (academics).  They appear to 
have one main rural campus, spread over a largish area.

Not that I wish to stir things up with regard to the RIPE/JANET 
allocations or anything ...

Jethro.

Subject: Re: IPv6 Address Blocks

Hello Tony,

The University of new Hampshire acquired a /48 a couple years ago as that 
is what ARIN was offering.  Since then ARIN policy has changed and they 
are more inclined to issue /32s to higher Ed if you can make a case as a 
LIR (local Internet Registry).  We are currently in the process of 
transitioning to a /32.  Some general items that may qualify your college 
is if your institution has customers outside the college, like k-12 
schools, libraries, non-profits, remote sites (research sites) or possibly 
even separate departments like CS, Electrical Eng., Physics or others.

In general we plan to assign /48s to different groups at UNH such as CS, 
RCC (Research Computing), UNH-IOL (interoperability Lab), Cooperative 
Extension, distance learning, WIFI networks, and others.

I did a little research and other universities of the size and character 
of UNH all have /32s. It may seem like overkill and probably is but it 
seems to be the standard for institutions like UNH.  The more research I 
did the more convinced I became that a /48 would at some point limit or 
capabilities.  As a final check, I asked industry leader in IPv6 testing 
and certification, UNH IOL (www.iol.unh.edu) , what they thought and they 
confirmed that a /32 is the norm for our type of scenario.

We have around 12k undergrads and act as an ISP for various groups around 
the state.  The /32 should give us the opportunity provide IPv6 services 
limited only by imagination.

I hope this is some help.  Let me know if you have further questions.


Thank You,
Scott Kitterman

You can easily get a /48 - that's what we got. My understanding is that is 
what most folks will get. If you can make a good case you might be able to 
get something slightly larger (like a /46).

A /48 should be plenty big...

/32 is about the size recommended for an ISP (which I think a University 
is)  but I sure would like to see what other universities are planning 
for.
       I've got an IPv4 "B" block now and with about 5000 students it 
gives me lots of good options without having to compromise any addressing 
plans. The /32 would get me 79 septillion IP addresses...seems like enough 
;-)... but what's the going reservation size you have or are 
contemplating?
