Turn a shared IP into hosted-domain research
When a teammate posts an IP for investigation, Notis can retrieve its hosted domains and keep the first research step in the thread.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Hosted Domains Lookup
Tool to retrieve hosted domains for a given IP address. Use this after validating the IP.
Why this helps
An IP investigation can turn into a chain of small lookups that is easy to postpone or lose track of.
- Start hosted-domain research directly from the IP discussion.
- Avoid a manual copy and switch into another lookup flow.
- Keep the initial result connected to its reason for investigation.
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 tell Notis to find domains hosted on a valid IP shared for investigation in Slack.
- 3Give Notis one plain-language instruction to recognize the investigation context and identify the IP.
- 4Pick the Slack channel-message trigger and a report channel, then test with a known valid IP.
Questions about this workflow
Will it work with any IP address?
The action requires a valid IP address and returns hosted domains when data is available.
Does this show every domain on an IP?
Results depend on the lookup data available for that IP and should be treated as returned research results.
