Domains

domains

Optional

Domains to look up. Full URLs and email addresses are accepted too - 'https://www.example.com/pricing' and 'sales@example.com' both become 'example.com'. Anything that is not a domain is reported with a reason instead of being silently skipped.

Type:array

Default:

[
  "mozilla.org",
  "github.com",
  "wikipedia.org",
  "cloudflare.com",
  "shopify.com"
]

Look up registration data (RDAP)

checkRdap

Optional

Ask ICANN RDAP for the registrar, registration date, expiry date and registry status. RDAP only answers for registrable domains, so for a subdomain the parent domain is queried and reported in the 'rdapDomain' column. Turn off to make runs faster when you only need DNS and TLS.

Type:boolean

Default:true

Check the TLS certificate

checkTls

Optional

Connect to port 443 and read the certificate: issuer, validity dates, whether it has expired and whether it actually covers this domain. Turn off to skip the connection.

Type:boolean

Default:true

Timeout per lookup (seconds)

timeoutSecs

Optional

How long to wait for one RDAP request or one TLS handshake before giving up on it.

Type:number

Minimum:3

Maximum:120

Default:20

Retries on temporary failures

maxRetries

Optional

How many times to retry a lookup that failed for a temporary reason (timeout, connection reset, HTTP 5xx). A domain that genuinely does not exist is never retried - that is already an answer.

Type:number

Minimum:1

Maximum:10

Default:3
