This data call returns the RPKI validity state for a combination of prefix and Autonomous System. This combination will be used to perform the lookup against the RIPE NCC's RPKI Validator, and then return its RPKI validity state. More specifically, according to its documentation:

When you supply a combination of Autonomous System (AS) and prefix, they will be matched against all the Validated ROA Prefixes (VRPs) that are in the cache of the RPKI Validator

This datacall has 3 supported versions:

• preferred_version=0.1 (deprecated) which queries an instance of the RIPE NCC Validator 2.7 running at the RIPE NCC
• preferred_version=0.2 (deprecated) which queries an instance of the RIPE NCC Validator 3 running at the RIPE NCC
• preferred_version=0.3 (current) which queries an instance of Routinator running at the RIPE NCC

Note: All of the validator instances used by RIPEstat are production grade. RIPEstat does not fetch information from rpki-validator.ripe.net or localcert.ripe.net, but from internal instances.

Parameters

Key	Value	Info	Required
resource	ASN	The ASN used to perform the RPKI validity state lookup.	YES
prefix (or prefixes)	prefix	The prefix (or comma-separated list of prefixes) to perform the RPKI validity state lookup. Note the prefix's length is also taken from this field.	YES

Output

Data

Key	Info
status	The RPKI validity state, according to RIPE NCC's RPKI validator. Possible states are: valid - the announcement matches a roa and is valid invalid_asn - there is a roa with the same (or covering) prefix, but a different ASN invalid_length - the announcement's prefix length is greater than the ROA's maximum length unknown - no ROA found for the announcement
description	The description that ended in the returned status.
prefix	The prefix this query is based on.
resource	The resource (ASN) this query is based on.
