Inactive IP Address
No open ports or services detected on a resolved IP address.
Severity: Warning
What does this mean?
DNS Watchdog resolved a DNS record to an IP address, but when it scanned that IP, no open ports or running services were detected. The host appears to be completely unresponsive — it did not reply to any connection attempts on any of the scanned ports.
Why this is a problem
An inactive IP address associated with a DNS record could indicate several things:
- The server has been decommissioned but the DNS record was not cleaned up
- The host is behind a firewall that blocks all inbound traffic (which may be intentional)
- The IP address has been released and is no longer assigned to your infrastructure
- The server is temporarily down
Stale DNS records pointing to inactive or released IP addresses are a security risk. If the IP is reassigned to someone else, your DNS record will point to infrastructure you do not control.
What you should do
- Verify whether the server at this IP address is still in use
- If the server has been decommissioned, remove or update the DNS record
- If the host is intentionally firewalled, you can ignore this issue
- Check with your hosting provider to confirm the IP is still assigned to your account
