schoondoggy 890 Posted June 8, 2015 Share Posted June 8, 2015 Just curious on how you have set up your home networks and why. I have been fielding a lot of network questions lately: DHCP vs fixed IP? Do you group devices by ranges? Reserve ranges? Servers at high end of the range? Link to post Share on other sites
nrf 135 Posted June 8, 2015 Share Posted June 8, 2015 (edited) I use a mixture - servers and infrastructure get fixed IPs. Since some routers require reserved IPs to fall within its dhcp range and some outside I don't mess with it. I have frequently changed routers over the years and doing that keeps the process of changing cleaner low IP range: assigned directly to main gateway/router (sophos in my current setup) and smart switches middle IP range: for DHCP usage high IP range: assigned directly to wireless access points, servers, cameras, and anything that gets a firewall rule Edited June 8, 2015 by nrf 1 Link to post Share on other sites
jmwills 284 Posted June 8, 2015 Share Posted June 8, 2015 I usually group IP Addressing by functionality. I even go to the extreme of keeping domains within a range. 1 Link to post Share on other sites
jsox 58 Posted June 8, 2015 Share Posted June 8, 2015 as much DHCP as possible fixed IP where not possible 1 Link to post Share on other sites
oj88 134 Posted June 8, 2015 Share Posted June 8, 2015 My IP addressing scheme using a private /24 mask: 1-10 - Server, NAS, ESXi Mgt 11-30 - IP Cameras (will soon be moved to a separate VLAN) 31-40 - Wireless Access Points and Network Printers 41-50 - IP Phones (will soon be moved to a voice VLAN) 51-220 - DHCP pool for clients (including static DHCP bindings) 221-254 - All other network elements; Routers, Switch, networked UPS, OpenVPN gateway My test lab is on a different subnet behind a secondary router. 1 Link to post Share on other sites
yodafett 97 Posted June 9, 2015 Share Posted June 9, 2015 Mine is varied but have used it for 20 years so not changing now 1 router 2 printer 3 main pc After that odds are static pc and evens are device like NAS,ilo,rac, vhost 51-60 ip cam 21-30 network equipment ups, ap, switch 100-110 cable boxes Dhcp is 150+ 64-96 are reserved for bandwidth limiting PC and phones (wife and kid) We're I to redo it 1-10 network equipment (router, switches, ups, printer, Nas and AP) 11-20 servers and VM host 21-30 RAC/ilo/Kvm 31-50 VMs needing static IPs 60-79 IP cameras 100-110 cable boxes 128-159 static ip desktop 161-192 dhcp for shaped or filtered traffic 194-254 dhcp Seems extreme but 50-64 IPs seems common now in my house 2 Link to post Share on other sites
Trig0r 210 Posted June 9, 2015 Share Posted June 9, 2015 Mixed. Servers, printers, AP's, VM's, ATV's and stuff like that get statics due to certain rules etc that I have setup on the network, devices that come and go are on DHCP, so normal PC's, devices that connect via wifi and so on...

LoneWolf 157 Posted June 29, 2015 Share Posted June 29, 2015 (edited) Servers, switches, appliances (e.g., a NAS), and printers get a static outside the DHCP range. At home, several of my PCs and other devices (like the Tivo) get a DHCP reservation so that I can keep them straight when using Remote Desktop or VNC. I also usually have a general idea of what I'm going to do with my statics, for example: .1 - .9 = Network equipment, such as my router, wireless bridge, access points .10 - .19 = My managed switches .20 - .29 = My server range, which would also include the HP iLO, and if I have a NAS device .30 - .39 = My printer range If I had VoIP or cameras, I'd have a group for each of those. However, I might do a VLAN for each, with a static route if they needed to communicate back to a server device on the main LAN. My DHCP range is like, .120 - .170; I'll never need that many addresses. The first ten are DHCP reservations for devices, the rest are open. Note, if I was doing it in a work LAN environment, I might do this for a small business, but I'd be doing it a bit different for a medium to large client.

itGeeks 187 Posted September 7, 2015 Share Posted September 7, 2015 (edited) Just curious on how you have set up your home networks and why. I have been fielding a lot of network questions lately: DHCP vs fixed IP? Do you group devices by ranges? Reserve ranges? Servers at high end of the range? Kevin I know this post is aged but I wanted to ad what I do, I use all static-dhcp for all my devices. I don't like to hard code anything on the devices because if I want to make a change I would need to go to each device to change the IP address so by using static-dhcp I only have to go in to the dhcp server to change the IP address for the device. I group everything as follows for home/home office/small business networks-- I need to add this later, I only hope this forum will let me edit my own post. This forum for some reason does not let me edit my own post after a period of time. Admins/MODS, Y does this happen? I can post something then several hours later I want to add/edit something I said and I cant so I have to double up on my post. I understand security and all that but security vs usability needs to be balanced better. I should always be able to go back on one of my own post and edit it.
