Hey,

I've nothing better to do tonight so I thought I'd sort out my IP address allocation before BT turn up tomorrow to install Infinity2.

Anyway, I usually always keep the router on 192.168.1.254 and everything else that is hard wired goes sequentially from 192.168.1.1. All wireless devices are assigned a DHCP address beginning 192.168.1.100 and above.

So, why the thread? Well it's a bit of a "what would you do" really. I like order and logical addressing :D

I have the following devices in a rack / wired around the home

HP switch
Fibre modem
Asus router
Sky box
PS3
Bluray player
Onkyo AV amp
Samsung laser printer
Office PC

Would you keep the router at .254 and the switch as .1 and assign the new modem at .2, or put the new modem as .1 router as .2 and move the switch to .254, "out of the way"?
 
I say who cares. Just leave it as is, as long as you remember what the router is, and what the switch is, does it matter what the others are?

Don't mean that to sound :mad: if you know what I mean :p
 
And I thought I was bad :)

I'd be tempted to have the network management stuff as 1 and 2, then DHCP/set everything from 100 onwards.

That said, mine's a bit all over the place too. ADSL router on .1, WiFi access point on .100, DHCP .200 onwards and stuff that I need to remember the IPs of are .x.
 
I use 254 for router, then for same subnet infrastructure devices count down.

Wireless AP is .253 for example.

Clients just get DHCP issued IPs from 1 to 100. MAC address reservations where needed.
PPTP VPN clients get issued from 200 to 225.

As long as infrastructure is segregated from clients I see no real other logical separation, except where VPN clients etc are involved.
 
I use .1-9 as infrastructure equipment, 10 for my nas, 50-150 as static ip's and 150-200 for DHCP.

And because I was bored of the usual 172.16.x.x or 192.168.x.x ranges I use 10.x.x.x

So, to answer your question, for me It'd be modem as .1, router as .2 and the switch at .3 :)
 
I have 2 machines set as static DHCP (router set's the IP via MAC address), the rest can do what they want :)
 
I forgot to mention, all the IPs are assigned by static DHCP except the wireless items which fall in a DHCP range. This way I can log in to the router and instantly see what's what.

Not that anyone cares, but this is how I configured it..

192.168.1.x
Echolife VDSL modem .1
Asus RT-N66U router .2
Sky HD+ .3
PS3 .4
Panasonic Blu-ray .5
Onkyo AV amp .6
Office PC .7
Samsung laser printer .8
3 home signal box .9

Wireless devices .100-.200 via DHCP

HP Switch .254

This gives me scope to expand on fixed addresses, whilst keeping the switch in a memorable address for when I do need to log in to it.
 
It literally doesn't matter what IP address something has, as long as your DHCP and DNS is setup correctly you never need to care about IP address.

I think he means DHCP.
Click to expand...

DHCP was inferred, the point was I don't really care what IP address my devices are on because when I want to connect to them I type their hostname like nas, router, laptop, switch, etc. I have a lot of devices running and use DNS so this stuff doesn't matter to me.

Your mileage may vary is because not all consumer hardware will support this / just work. Remembering IP addresses should be a non-issue if you want it to be.
 
I generally leave router as 254, then anything i NEED to have a static IP as 253, 252 or 1,2. Just makes it easy to remember. Most things theres no reason to have a static IP for, just causes more issues. Thats why DHCP was invented after all :D
 
10.0.0.x -- MUCH easier to type than 192.168.0.x !!

0-10 for routers, 10-99 for other static ones (mainly 10, 20, 30, 40 etc with a few associated ones eg 11, 31, 32 etc). 100-150 for DHCP pool.

I use .1 for firewall LAN, 2-9 for clients, 10-19 for servers and 20-22 for DHCP for "visitors" and 23-31 for printers, switch, WAPs etc - I have a public /27
