Why check DNS exposure?

A DNS service without proper access restrictions can be exploited without the company noticing. Early identification helps protect availability, reputation, and operations.

Infrastructure abuse

Third parties can use an open resolver to amplify attacks and consume resources from your connection.

Reputation and blocks

Misuse of your address can lead to abuse reports, blocks, and damage to the company IP reputation.

Invisible operational risk

Without monitoring, exposure may remain active for a long time. The diagnostic creates a starting point for correction.

Frequently asked questions

Do I need to install anything?

No. Enter a public IPv4 that you manage and confirm that you are authorized to verify it.

Can I test a private IP or hostname?

No. The tool accepts only a global public IPv4, without a hostname, URL, CIDR, or range.

Does a negative result mean I am completely safe?

No. It means no evidence was found in this verification. The report helps review other relevant interfaces, rules, and settings.
