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
