I agree but unfortunately whilst the smaller players in the market have had to adjust over the years, the big players have had a free run at the expense of everyone else.

If all of the uni's and big businesses that have ridiculous amount of public ip's learned how to use NAT then the V4 space would have lasted longer. It would have been easier for organisations that actually needed more public IP's to get them too over the last few years. -----Original Message----- From: Kramer, Jack [mailto:jack.kra...@ur.msu.edu] Sent: Saturday, 5 February 2011 1:20 AM To: NT System Admin Issues Subject: Re: [semi-OT] Last IPv4 address blocks assigned Ouch! I would say at least 30,000 to 40,000 user machines plus things like servers, HPCC farms, appliances, and VMs. We have a student population of about 47,000 plus about 11,000 staff, though not all of those users are on campus at any given moment. There's no NAT on campus so unless you set up a NAT device yourself you're going to get a public IP. Our dormitory population is about 18,000 - each of those machines receives an IP from the dormitory DHCP range, which is protected by the campus border firewall/IPS. Wireless machines also receive externally facing IPs but are shielded by the border systems as well. (And, of course, lots of students have wireless laptops or things like iPods, etc.) Staff machines can either be DHCP or static; static addresses are publicly accessible by default while DHCP ranges are protected by the border unless requested otherwise. Obviously not every student is online at any given moment, but their IP reservations are protected by the campus DHCP servers for something like 3 months from last activity - just long enough that you have to get a new reservation when you come back from summer break. The campus backbone network is where things get interesting - we've just been upgraded to 10Gb for building interconnects with most buildings at 1Gb internal networking and our fibre network extends into some areas of downtown Lansing (the local hospital, for instance) as well as to some of our satellite sites around the state. It's a big network, even if my little departmental piece of it isn't so vast. ---- Jack Kramer Computer Systems Specialist University Relations, Michigan State University w: 517-884-1231 / c: 248-635-4955 On 2/4/11 9:57 AM, "Martin Blackstone" <mblackst...@gmail.com> wrote: >50 > >-----Original Message----- >From: Crawford, Scott [mailto:crawfo...@evangel.edu] >Sent: Friday, February 04, 2011 6:55 AM >To: NT System Admin Issues >Subject: RE: [semi-OT] Last IPv4 address blocks assigned > >out of curiosity, how many computers does that serve? > >________________________________________ >From: Kramer, Jack [jack.kra...@ur.msu.edu] >Sent: Friday, February 04, 2011 8:13 AM >To: NT System Admin Issues >Subject: Re: [semi-OT] Last IPv4 address blocks assigned > >The nice thing about being at a public university - 520,000 IP addresses. >(Michigan State has 35.8 through 35.15.)
