Notification for traffic from unseen host

[erieflin]

Is there an existing issue for this?

Describe the solution you'd like

For the custom notifications, it would be useful to have a notification that can occur the first time traffic from/to a host is detected.

Ideally there would be some way to keep this list persistent across runs. (but that might be a bigger item)

In a similar previous tool that i used, a feature like this was used to "warn" on new traffic, and basically allowed a continually running scan to provide some active visibility for increased security

For example, if you downloaded something that looked innocent, but suddenly your computer starts making a lot of requests to strange hosts in a foreign country seemingly unrelated to the download, a notification here could alert that something may be up

Is your feature request related to a problem?
