On the internet, routes are announced as prefixes: an autonomous system tells its neighbours via BGP that it can deliver traffic for, say, 144.122.0.0/16 (Middle East Technical University, AS1967). This tool looks a prefix up in our daily copy of the global routing table and shows three things:

Exact announcements: which AS originates exactly this prefix. More than one origin (a MOAS) is normal for anycast services and some multihomed networks, and suspicious otherwise.
Covering routes: less-specific announcements that contain it. Traffic follows the most specific route, so a covering route matters if the more-specific one disappears.
More-specifics: announcements inside it, which may belong to other networks (customers, or a hijack).

Each announced route is also checked against the RPKI: whether a ROA authorises its origin AS.

The table is the view from APNIC’s route collector. Most of the global table is the same from everywhere, but a route that is filtered before it reaches that collector will not appear.

Why is my /24 not listed but a /16 is?

Your addresses are announced as part of the larger block, and no one announces the /24 separately. That is the normal case for most customers of a provider.

What is a more-specific hijack?

Someone announces a longer prefix inside your space. Because routers prefer the most specific route, traffic goes to them. RPKI with a strict max length makes such announcements invalid.

Can I enter a single address?

Yes. The tool then shows the most specific announced route that contains it.
