Initially, we had two class B allocations. When address space was abundant we provided one to our Hospital. Let's just say the chances of getting some back are pretty low.
We're concerned that ARIN won't approve a new allocation because the hospital's address utilization appears low. A majority of their address space is now behind a firewall. -Neil -- Neil Johnson Network Engineer The University of Iowa W: 319 384-0938 M: 319 540-2081 http://www.uiowa.edu -----Original Message----- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[EMAIL PROTECTED] On Behalf Of Kevin Miller Sent: Thursday, May 29, 2008 9:38 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Using Private IP addresses for wireless users. Neil, With justification, you can request additional addresses from ARIN. I think because many colleges and universities have legacy allocations, the processes for doing so are unknown or believed to be cumbersome. I would say that the ARIN processes are geared more for service providers, but things like "deploying a new campus wide wireless network" or "adding 500,000 square feet of building space that needs IP addresses" are, IMO, good justification for requesting additional space. Now, it may be difficult to justify if you have a lot of internal fragmentation (e.g. blocks allocated that have low usage), but it might be simpler than going down this path. Of course, the clock is ticking on how much more ipv4 can be allocated (c.f. ipv6). -Kevin Johnson, Neil M wrote: > We will be out of address space for one of our wireless nets (currently a > /21) in the fall. > > We do not have a larger block available, and attempts to obtain additional > address space by fall are not looking promising, so there is a distinct > possibility that will have to move our wireless users to private address > space. > > So I'm looking for information from other institutions who use private > address space for their wireless networks. > > We are primarily a Meru shop, although we have about 86 Cisco LWAPP AP's in > production.
