When one logs in to the RIPE portal, one can easily see a tab for 3 different resources (My Resources tab): IPv4, IPv6 and ASN But how does one see all the inverse domains that are "owned" by that LIR?
With 'inverse domains', do you mean the in-addr.arpa & ip6.arpa reverse delegations per prefix? You will have to go to: My Resources -> IPv4 / IPv6 Tab there per prefix below it "allocated PA" or similar, then the name of the prefix and a green "tag" with IRR or "rDNS" indicating that rDNS is set for it. Click on the prefix, and at the bottom you will have "Domain" and the delegated in-addr.arpa or ip6.arpa domain along with Manage to do something with it, though effectively updating the whois/RPSL object (and supports DNSSEC :) ). I do not think there is currently a "list of all domain objects related to LIR" view in the webui. If you know the typical owner of the objects, one could do a whois inverse search: whois -h whois.ripe.net -- -r -i admin-c,tech-c YOUR1-RIPE -T domain whois -h whois.ripe.net -- -r -i mnt-by YOUR-MNT -T domain You could also search through: https://ftp.ripe.net/ripe/dbase/split/ripe.db.domain.gz Or for automated way use the API: https://www.ripe.net/publications/documentation/developer-documentation/lir-... this will only show you the objects for that LIR account, which might be the most accurate if you have a lot of objects. Depending on what you are looking for, maybe old/outdated domain objects, I would take the list of prefixes (eg quickly from bgp.tools below), reverse them and match them with domains in the above gzip file, that would be the quickest route. I wonder if, especially on an older/long-standing LIR if one can find prefixes with domain objects that are not directly connected using the LIR portal API though, time can cause differences after all :) Btw, the amazing BGP Tools has a view for at least the IPv4/IPv6/ASN resources: https://bgp.tools/rir-owner/tld.lirname Though that does not cover reverses.
