Hi Andrew, RIPEstat makes this easy for resources that belong to the RIPE NCC region: 1. Go to stat.ripe.net https://stat.ripe.net 2. Look up the ASN (for example, AS3333) https://stat.ripe.net/as3333 3. On the "Database" tab, navigate to the Registry Browser widget and click on the organisation object located in the right-hand list 4. The left-hand table lists all aut-num, inetnum and inet6num objects registered under this organisation object. https://stat.ripe.net/as3333#tabId=database&database_registry-browser.resource=organisation:ORG-RIEN1-RIPE Plans are to extend the Registry Browser to other RIR's databases as well. In the meanwhile the Routing Consistency can be of help for resources outside our region. https://stat.ripe.net/widget/as-routing-consistency#w.resource=AS3333 This widget lists and crosschecks routes found in BGP routing data (based on RIS [0]) as well as the RIPE NCC's and RADb's [1] Internet Routing Registries. The "Database" tab might contain other widgets that you find useful in case you are looking for Registry-related information. If you are interested in BGP routing-related data, the "Routing" tab is for you; specifically I'd like to point out the Announced Prefixes and Routing History widget. In case you have any questions on the presented information, please refer to the widget's "Info" button and/or RIPEstat's documentation [2].

Is there a tool or method to determine IP blocks assigned to an organization by ASN? I.e. if I have an organization's ASN number I want to know all blocks assigned to that ASN.
Thank you.
