You need an init start up file that would create a /etc/issue with the resulting ip address being given by the dhcp server, each time the system boots up.

Since you are in Ubuntu you can use hostname -I to obtain the currently actives ip addresses in your system.

You can test by just manually appending the IP 192.168.1.149 to /etc/issue and login in again.
Question:
How do you login?
Terminal Console?
SSH session?

Yes it displays the added text.

I tried using this with negative results, I believe it is using an init start up.

Code:
hostname -I

returns with my ip, but not sure how to implement this yes.

Yes it will display arbitrary text.

Normally ssh.

This issue is reproducible while using a VM (emulated monitor w/ no gui or X running automatically) or using a real monitor to a CLI Login prompt.

In case you expect it, the /etc/issue will show only when you are at the console. But of course, if you can ssh you know what IP is already and you do not have to see it.

You should be able to see the pre-login if you are at the console of a VM.

In your script where you use the ifconfig command, substitute it for
Code:
hostname -I >> /etc/issue
