Put priority IP checks on a steady cadence
A recurring hosted-domain lookup can bring a defined set of IP research back into view without relying on someone to remember the next check.
Trigger
Recurring schedule
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Action
Hosted Domains Lookup
Tool to retrieve hosted domains for a given IP address. Use this after validating the IP.
Why this helps
Repeated checks can fall behind when the same small task competes with daily founder priorities.
- Create a consistent routine for known priority IPs.
- Keep recurring research visible in a Slack report channel.
- Reduce manual prompts and repeated context setup.
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 your priority IPs on a recurring schedule.
- 3Describe the valid IP list or its approved source and the desired result in one plain-language prompt.
- 4Select a Notis cron trigger, set the cadence and report channel, then test with one valid priority IP.
Questions about this workflow
Does the lookup monitor changes continuously?
No. It runs on the schedule you choose and returns hosted-domain information available at that time.
Does the workflow validate IPs?
The hosted-domains action should be used after validating the IP. Describe how Notis should handle invalid or missing entries.
