På internet annonseras rutter som prefix: ett autonomt system talar om för sina grannar via BGP att det kan leverera trafik till till exempel 193.166.0.0/15. Verktyget slår upp ett prefix i vår dagliga kopia av den globala routningstabellen och visar tre saker:

Exakta annonser: vilket AS som är ursprung för just det här prefixet. Fler än ett ursprung (MOAS) är normalt för anycasttjänster och en del nät med flera förbindelser, annars misstänkt.
Täckande rutter: mindre specifika annonser som innehåller det. Trafiken följer den mest specifika rutten, så en täckande rutt spelar roll om den mer specifika försvinner.
Mer specifika rutter: annonser inuti prefixet, som kan tillhöra andra nät (kunder – eller en kapning).

För varje annonserad rutt kontrolleras också RPKI: om en ROA auktoriserar dess ursprungs-AS.

Tabellen är vyn från APNIC:s ruttinsamlare. Det mesta av den globala tabellen ser likadant ut varifrån man än tittar, men en rutt som filtreras bort innan den når insamlaren syns inte.

Vanliga frågor

Varför syns inte mitt /24 men väl ett /16?

Dina adresser annonseras som en del av det större blocket, och ingen annonserar ditt /24 för sig. Så är det för de flesta av en operatörs kunder.

Vad är en kapning med ett mer specifikt prefix?

Någon annonserar ett längre prefix inuti din adressrymd. Eftersom routrar föredrar den mest specifika rutten går trafiken till dem. RPKI med en strikt maxlängd gör sådana annonser ogiltiga.

Kan jag ange en enskild adress?

Ja. Verktyget visar då den mest specifika annonserade rutt som innehåller adressen.
