I feel like I am trying to herd cats at work – I would really like to standardize how we assign IP addresses within DHCP and the subnets, but each administrator has his or her own “Best Practices” ideas about IP Address schemes – one person uses x.x.x.1 as the gateway/router, while another uses x.x.x.254, and yet another will use x.x.x.2. One administrator will use x.x.x.30 through x.x.x.100 as the DHCP range, while another will use x.x.x.100 through x.x.x.200 and so on. One administrator even used a range in the middle of his DHCP scope for switches, routers, and servers!
I want to do something like this:
x.x.x.1 = default gateway (assuming /24)
2-20 = network access devices
21-40 = server devices
41-60 = network peripherals (printers, etc.)
61-80 = reserved for special devices
81-100 = static addressed workstations
101-200 = standard DHCP pool of addresses
201-254 = VOIP devices (switch, adapters, etc.)
BUT ~ I can’t convince everyone to do it the same way. They want to see a “Best Practices” document from an authoritative source, and I don’t blame them, I do too. This has led into some heated but healthy discussions about ITIL and IT Service Management, areas in which I am still learning more.
Any feedback? Does such a document exist?
Thanks in advance!
