Oh yeah... no DHCP'd servers here.
-sc From: James Rankin [mailto:[email protected]] Sent: Friday, December 18, 2009 3:38 AM To: NT System Admin Issues Subject: Re: Need more IP addresses I've got all my servers on DHCP these days, except for a very select few (WebSense being one that springs to mind that needed a static IP). I don't get any problems really, except for occasionally having to flush DNS records when we bring templates online for patching and they pick up a different address. The live servers don't seem to change very much at all. Do most people use full static addresses for their server ranges? 2009/12/18 tony patton <[email protected]> we use a similar approach: 10.site.<section>.device, as in 10.2.120.1 where each floor of our buildings is split into seperate address for left and right side. Full dhcp, except for servers. Regards Tony Patton Desktop Operations Cavan Ext 8078 Direct Dial 049 435 2878 email: [email protected] From: "Matthew W. Ross" <[email protected]> To: "NT System Admin Issues" <[email protected]> Date: 17/12/2009 21:33 Subject: RE: Need more IP addresses ________________________________ We use a 10. addresses, and separate information based on the IP. For example: 10.20.103.250 That can be read as: 10.High School.Room 103.Printer 1 Or: 10.Building.Room.Device We have all of our addresses statically assigned in DHCP, so we can keep this kind of address logic. For example, we always use IP address ending in 250-254 for printers in the room. Obviously there are flaws with this system. I can't correctly use room 402, for example. Also, when somebody moves a computer around without our knowing, the IP address no longer is useful. Another method we use when a networkable item has no home is 10.99.xxx.xxx. I this case, the 99 means this item's IP is based on it's inventory tag/barcode. For example, if the IP address was assigned to 10.99.45.23, I would know that this is tagged with barcode 4523. I then use my inventory to look up further information on the device. This would be valid up to Barcode 25599 (10.99.255.99), which is enough for us for some time. --Matt Ross Ephrata School District ----- Original Message ----- From: Ben Schorr [ mailto:[email protected] <mailto:[email protected]> ] To: NT System Admin Issues [mailto:[email protected] <mailto:[email protected]> ] Sent: Thu, 17 Dec 2009 13:16:54 -0800 Subject: RE: Need more IP addresses > We actually have one client with a Class B (255.255.0.0) network and I > have to say...we really like it.
