Hi Adam,

Good to hear that you find this tool useful.

“(No valid route object!)” means that no route object was found for the announced prefix. It’s good practice to have route objects for all your prefixes in one the IRR’s.

With valid we mean: an Exact match, ie, same prefix and same prefix length and same origin AS.

This would be a valid route object for 145.88.0.0/15 announced by AS1103

whois -h whois.radb.net 145.88.0.0/15 route: 145.88.0.0/15 descr: LUMC-NET HVUNET origin: AS1103 notify: info@surfnet.nl mnt-by: AS1103-MNT changed: peter.vons@sara.nl 20020227 source: RIPE

Hope that answers your question.

What does “(No valid route object!)” mean after an announced prefix? All of my routes are reachable so I’m not understanding this one.

Thanks so much for this site/tools. It has been a huge help for me.
