BGP प्रीफ़िक्स लुकअप

एक प्रीफ़िक्स (या एकल पता) दर्ज करें। वैश्विक रूटिंग टेबल की हमारी दैनिक प्रति से उत्तर।

उदाहरण:

58.224.0.0/13

एक कलेक्टर का दृश्य (APNIC)। उस कलेक्टर तक पहुँचने से पहले फ़िल्टर किया गया रूट सूचीबद्ध नहीं होता।

ठीक इसी रूप में घोषित

कवर करने वाले रूट

On the internet, routes are announced as prefixes: an autonomous system tells its neighbours via BGP that it can deliver traffic for, say, 2.48.0.0/14. 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.

अक्सर पूछे जाने वाले सवाल

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.
