Other than 1 and 255, the only standards I'm aware of are company specific standards. We assign all workstations by dhcp in the range of 101-254. All non-workstation system use a fixed IP in the range of 2 - 100. The fixed IP's are grouped by function. 2 - 10 Linux (non-Windows) servers 11 - 20 Special purpose computers 21 - 30 switches 31 - 60 printers & faxes 61 - 70 Exchange servers & virtual servers 71 - 80 Citrix servers 81 - 90 SQL servers 91 - 100 Firewalls, Domain Controllers & UPS's Larry -----Original Message----- From: tclug-list-bounces at mn-linux.org [mailto:tclug-list-bounces at mn-linux.org] On Behalf Of Thomas Rieff Sent: Wednesday, December 02, 2009 1:06 PM To: TCLUG Subject: [tclug-list] Internal IP Address Guidelines Are there any basic guidelines for assigning ip address to various devices on the internal network???
