How can I find out about connecting a new device to your network?

All good day, am interested in this question, it is clear about the network scanning and monitoring, but is interested in the emergence of a new device in the network, for example setting up a new PC and I need to know its ip address and actually something like the alert, any idea?
Interested in the actual next OS, debian and windows server 2012 r2
Thanks in advance for your answers.

arpwatch
the logs of the dhcp server
monitoring of mac on the ports of the switch

In the General case it is difficult to say something, it is necessary to know the structure of the network, equipment...

If Your IP is taken from DHCP, you can monitor the results new there.
But at the stage before that is MAC only, it is possible to dance from him. Then you need the monitoring service switches.

What do you want then? Maybe you can just Bloch unfamiliar poppies and all:? And the new You will be informed when it is necessary to connect
actually I want to create an image and quickly deploy user workstations, the man took the computer, I saw that a new car online and gave her the ip in the list, although I may be wiser) - robert_Dicki commented on July 2nd 19 at 14:22
And not simply to fill the image over the network at once, huh?
Well, besides the car You already have. That took her - what else is needed?

By the way, You never said where the IP is taken - Clement_Johnst commented on July 2nd 19 at 14:25

arpwatch - a wonderful thing :) musthave for any router.

How to make in Windows - I don't know, Windows is an axis for toys and movies. You may be able to check on the switch to send trap by snmp, unless the switch knows that.
