🌐 Check DNS propagation with resolver evidence

DNS administrators, DevOps teams, and site owners can compare DNS answers for each domain and record type across 10 public DNS resolvers. The Actor saves propagation status, resolver coverage, answer values, response times, TTL and cache details when available, and optional expected-answer checks so you can review a DNS change in one run.

🧭 Use cases

Compare resolver answers after a DNS change with a DNS Propagation Check.
Review a domain's resolver results with a DNS Propagation Checker.
Check selected DNS records with a DNS Record Checker.
Review selected answers for a domain with Check My DNS.
Run a focused DNS Check for chosen domains and record types.
Check several domains and record types with a DNS Checker.

📦 Returned data

The default dataset has one row for each submitted domain and selected record type. Each row keeps the answers and diagnostic details from the public resolvers, so you can see whether they agree. Add expected answers when you want each matching check to show a match, mismatch, or incomplete expected status. Turn on the run summary for grouped diagnostic details.

▶️ Running the Actor

Add 1–200 domain names or hostnames.
Choose one or more DNS record types. The same types are checked for every domain.
Add expected answers when you want to compare selected resolver answers with values you provide.
Set the resolver query timeout from 100 to 60,000 milliseconds, if needed.
Run the Actor and open the default dataset. Turn on includeSummary when you also want the grouped run summary.

The prefilled input checks example.com for an A record with a 5,000-millisecond timeout. A DNS check can use the same settings or add more domains and record types.

🧾 Input

Provide the public input fields below. domains and recordTypes are required.

Field	Type	What it does
`domains`	array of strings	Required. Checks 1–200 domain names or hostnames. The same selected record types are used for every domain.
`recordTypes`	array of strings	Required. Selects one or more DNS record types: `A`, `AAAA`, `MX`, `CNAME`, `TXT`, `NS`, `SOA`, `PTR`, or `CAA`.
`expectedAnswers`	array of objects	Optional. Compares resolver answers with expected values for selected domain and record-type pairs.
`expectedAnswers[].domain`	string	Required inside each expected answer. Names one of the submitted domains to compare.
`expectedAnswers[].recordType`	string	Required inside each expected answer. Selects the DNS record type to compare.
`expectedAnswers[].expectedValues`	array of strings	Required inside each expected answer. Lists one or more DNS answer values to compare.
`queryTimeoutMs`	integer	Optional; defaults to `5000`. Sets the wait time for each public resolver query from `100` to `60000` milliseconds.
`includeSummary`	boolean	Optional; defaults to `false`. When `true`, saves a run summary grouped by resolver disagreement, incomplete coverage, and expected-value mismatch.

This is the public input used by a successful current-beta default run:

{
  "domains": [
    "example.com"
  ],
  "recordTypes": [
    "A"
  ],
  "queryTimeoutMs": 5000,
  "includeSummary": false
}

📤 Output

The Actor returns links to its public output storages:

Field	Type	What it does
`dataset`	string	Opens the default dataset with one row for each checked domain and DNS record type.
`summary`	string	Opens the optional run summary with grouped resolver disagreement, incomplete coverage, and expected-value mismatch details.

Dataset row without expected answers

A standard DNS check row has the following fields. Nested fields use readable dotted paths.

Field	Type	What it does
`domain`	string	Domain or hostname checked.
`recordType`	string	DNS record type checked.
`propagationStatus`	string	Shows `consistent`, `inconsistent`, or `incomplete` resolver agreement.
`coverageStatus`	string	Shows whether resolver coverage is `complete` or `incomplete`.
`checkedAt`	date-time string	Time when this check was completed.
`resolverResults`	array of objects	Answer and diagnostic details from each public DNS resolver.
`resolverResults[].resolverName`	string	Name of the public DNS resolver.
`resolverResults[].region`	string	Region reported for the resolver.
`resolverResults[].responseTimeMs`	integer	Resolver response time in milliseconds.
`resolverResults[].status`	string	Resolver request status: `answered`, `error`, `timeout`, or `noResponse`.
`resolverResults[].answers`	array of strings	DNS answer values returned by the resolver. The array can be empty.
`resolverResults[].ttlSeconds`	integer	Time to live for the returned DNS record, when available.
`resolverResults[].cacheStatus`	string	Caching state for the returned DNS record, when available.
`resolverResults[].errorMessage`	string	Resolver error message when the request fails.

💳 Pricing

The Actor charges $0.00045 for each successful propagation check for one submitted domain and DNS record type. A run can create one charged event for each successful domain-and-record-type check.

🔌 Integrations

Use the Apify API to start runs and read the default dataset or optional run summary. The structured dataset can feed your own DNS change checks or monitoring workflow.

❓ FAQ

What does consistent mean?

consistent means the answers returned by the queried public resolvers agree for that domain and record type. inconsistent means they differ; incomplete means there were not enough answers to make a full comparison.

Can this prove propagation everywhere?

No. It reports observations from 10 selected public resolvers, not a full geographic census of end users.

What happens when a resolver errors or times out?

The resolver result keeps a status such as error, timeout, or noResponse. coverageStatus can show incomplete coverage, and includeSummary can group incomplete responses.

Can I compare answers with expected values?

Yes. Add an object in expectedAnswers for a submitted domain and record type, then add one or more expectedValues. The row reports match, mismatch, or incomplete.

Can I check private DNS or DNSSEC?

No. The Actor queries selected public resolvers and does not validate DNSSEC chains.

Does it change my DNS records?

No. It reads answers and reports comparisons; it does not modify DNS records or deploy changes.

How many rows does a run save?

It saves one row for each submitted domain and selected record-type combination. The same selected record types are checked for every submitted domain.

What does queryTimeoutMs control?

It sets how long each public resolver query may wait, from 100 to 60,000 milliseconds. It does not change which domains or record types are checked.
