Notify me of changes

Get an email whenever we detect a change in an IP range you own — new open ports, new software or versions, freshly-matched CVEs, exposures, or expiring certs. You must own or control the range. For a stronger trust signal, verify ownership (HTTP file or DNS TXT) instead of self-certifying.

Between /16 and /32.
We'll also POST alerts here (Slack-compatible).
