Output
Data
| Key | Info |
|---|---|
| last_updated | holds the time the object was last updated (before the query_time) in the specified Whois database |
| object | holds the object name the query was based on |
| query_time | holds the time the query was based on |
| same_as_live | indicates whether the object at "query_time" is identical to the current live object. Only applicable for RIPE DB objects. Possible values: "yes", "no" or null. null indicates there has been no comparison with the live object and it is therefore unknown. This can be because the mechanism is switched off ("compare_with_live" query option), or it's an object outside the RIPE database. |
