Notis

See the domain footprint of a shared IP

When a review thread centers on an IP, Notis can list hosted domains as an early research step right where your team is working.

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

Technical investigations get harder to resume when each supporting lookup lives in a different tool.

  • Keep IP context and hosted-domain results connected.
  • Start infrastructure research from the team's review thread.
  • Make it easier to pick up the investigation after a context switch.

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 retrieve hosted domains for IPs shared in Slack review threads.
  • 3Describe the review context and the IP to use in one plain-language prompt.
  • 4Pick the Slack channel-message trigger and reporting channel, then test with a valid IP in a review message.

Questions about this workflow

Does this explain how the domains are related to the IP?

It retrieves hosted domains for the provided IP; further investigation is needed to interpret the relationship.

Can this be limited to review threads?

Describe the kinds of review messages that should trigger a lookup in the automation prompt.
