Handle IP research requests from direct messages
When someone sends an IP for a quick check, Notis can look up its hosted domains so the request does not become another item to remember.
Trigger
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Action
Hosted Domains Lookup
Tool to retrieve hosted domains for a given IP address. Use this after validating the IP.
Why this helps
Private requests can disappear from view while you move between deep work and incoming messages.
- Start research from a direct message without copying the IP elsewhere.
- Reduce the mental load of remembering small follow-ups.
- Keep a quick lookup close to the original request.
Setup
Build it in a few focused steps.
- 1Connect Slack and Ip2whois to Notis once in the portal.
- 2Create an automation in the portal, or ask Notis to find hosted domains when a valid IP is sent in a Slack DM for research.
- 3Write one plain-language instruction that explains how to identify a relevant request and its IP.
- 4Select the Slack direct-message trigger and a channel for run reports, then test with a real, valid IP request.
Questions about this workflow
Does this listen to channel messages too?
No. It uses the Slack direct-message trigger. Use a channel-message trigger for channel-based requests.
What if the DM is missing an IP?
Hosted Domains Lookup requires a valid IP address, so specify in the prompt how Notis should handle messages without one.
