Geek help needed on my network...

How do I find out the IP address of every device connected to my network?

Let me explain...
I have a Bt Home Hub 3, I know it's 192.168.1.254.
From there I have a network cable going to the TV and one going to a Belkin router which I'm using as a switch. I've configured the Belkin router with a static IP address, but I can't remember what it is.
From the Belkin I have a cable going to another router (D-Link), which I've also set up with a static address.
I have another old router in front of me and I'd like to use it at the TV, so I can have the TV, Western Digital TV Hub and a Sonos soundbar (yet to be purchased, and if my wife is reading this, it will cost less than your CRV's aircon repair) all connected up. But, based on how I've done it so far, I need to configure the router to a new static IP address.

So, what I want to do is find out what addresses I've used so far and perhaps actually save a file with the information.

Is there any easy way that doesn't involve connectin a computer to each router and tracert'ing it?

Thanks!
I had tried a couple of others, but with little success. Advanced IP Scanner did the trick.
Next router will be .248

Login to admin on your BT home hub. It should list the connected devices and IP address. Find the Belkin router address (and anything attached). Then login to the Belkin admin to find the D-Link router address (and any others attached to that).

Well no ones hacking into your network behind 3 firewalls!

I'm not sure if it works with old BT routers. But I have one of those - Might try it later!

If your summerhouse shares the same distribution board as the rest of your house, and if possible the same ring main, then the power line adaptor will work.

I've got a powerline adaptor in our office which is in a summer house in the garden. Works well and that's despite a pretty DIY, Heath Robinson electrical connection to the house.....

You shouldn't be using the WAN port on the 2 routers that are acting as WAPs. By doing so you are putting the stuff connected to the LAN port and wireless in a different subnet so they won't talk to stuff connected to your Home Hub.
You can use the spare routers as WAPs / switches but switch off DHCP Server on everything apart from the Home Hub and use the LAN ports not WAN. Everything will then be on the same subnet and will see each other.
Does that make sense? It's difficult to explain.

All depends really, if it's DSL then the format is RJ11 so it's impossible to do that. If cable or PPPOE type fibre, then just connect the other two routers to the main router via the inbuilt switch's via RJ45. Let the main router do DHCP and let the nodes do the SSID, it's all in the same VLAN unless otherwise configured so a case of let it do it's thang.

It's crazy I know but I have an internal MPLS network with a CME and a sip trunk for external calls because it cost's next to nothing for abroad. Multiple Vlan's trunked up to a FW for breakout point (Wireless, voice, DMZ). I was studying my CCIE and never took it down, just left it :D..

BigGreenZebra, makes sense, as does Shadowamd's reply. I'm not too worried about things talking to each other, so I've not really noticed, but I might play around with it later.
