Is there a utility which will give a list of all devices on my network with their IP addresses?

Every so often, my devices (printers, ATA etc are not available but then can be found on a different IP address. Today it was my VoIP ATA.and a printer.

Many thanks.

Cheers!

Whatever device acts as your DHCP server should have a list or page of current devices on the network that have been issued an address.

Suff like printers should be bound to a reserved/static DHCP address on the sever setup - such that it always gets the same IP. How you do that depends on the specifics of the device, but is usually pretty straightforward.

I use nmap for this.

Example:

nmap -PR -sP 192.168.1.0/24
Starting Nmap 7.91 ( https://nmap.org ) at 2021-06-05 16:44 BST
Nmap scan report for 192.168.1.2
Host is up (0.00013s latency).
MAC Address: 00:19:XX:XX:XX:XX (BSkyB)
Nmap scan report for 192.168.1.3
Host is up (0.00030s latency).
MAC Address: 68:5B:XX:XX:XX:XX (Apple)
etc
etc

I've long worked on the basis that if a device isn't likely to get carted off to someone else's LAN (eg printers, smart TVs, Airplay speakers...) then it gets configured with a fixed IP and I keep a list

Also allows me to keep things "tidy" by grouping similar devices together.

Advanced IP Scanner (Free) should fit the bill nicely!

Any critical devices (where you absolutely need to know the IP or change of IP will mess something up) should be set to static, either at the DHCP server or on the device itself.

+1 for NMAP (Zenmap GUI)

The web interface on your Draytek router (see manual) should give you all the details.

ARP Cache Table

DHCP Table

Or if you prefer you could telnet into the box (see manual page 447) and issue the show lan command.

Just bye the bye, when I was still working and there were thousands of IP's on the corporate LAN, we made it a strict rule when installing printers and drivers to the group using them to only use network names (not IP addresses) when addressing devices

Thank you for the reference to my Draytek. The DHCP Table has the information I wished for. Strangely(?) the ARP Cache Table offers two less than the DHCP Table.

One is a RokuStick for internet TV, the other one a COM-MID1 I am uncertain about. Google suggests "COM-MID1 is a host-name commonly assigned to the Wi-Fi adaptors found in Panasonic products." We do have a Panasonic TV, although switched off. Maybe the Wi-Fi is powered on standby.

Thanks again.

Cheers!

Thanks Iain, nmap certainly looks interesting, I will have a play later.

Cheers!
