However I'll assume you're asking a question about PromQL. What exactly do
you mean by a "Newly configured IP"?
If you're asking how to write a PromQL query to show newly-added scrape
endpoints, then you could use something like this:
up unless up offset 24h
But really, that's not telling you something about the node: it's telling
you about how you've configured prometheus. It tells you when something has
been added to the list of targets that prometheus scrapes in the last 24
hours (either because you've manually added it to the list of targets, or
via some service discovery mechanism that you've configured)
If you want to tell whether a node has assigned a new IP address to one of
its interfaces, you'd need to get those IP addresses into a metric. I
don't think node_exporter gives you that, so you'd have to add some custom
metrics (e.g. via the node_exporter textfile collector).
If you want to discover newly active IP addresses on your network, for
other hosts which are *not* running node_exporter, then you'll need to
scrape the ARP table of the gateway on your network. You may be able to
use snmp_exporter for that, although not all devices expose their ARP table
via SNMP: e.g. Cisco ASA firewalls don't, last time I tried.
