⚠ 9 MOAS 접두사es — 다중 원본 AS 감지됨

모든 MOAS 이상 →

이전에 AS에서 시작된 안정적인 접두사3 는 당사의 RIPE RIS 수집기에서 감지된 다른 ASN(MOAS — Multiple-Origin AS)에 의해 현재 공지되고 있습니다. 이는 종종 양성(애니캐스트, 멀티호밍 또는 최근 전송)이지만, 경로 유출 또는 접두사 하이재킹을 나타낼 수 있으므로 검사할 가치가 있습니다.

Frequently Asked Questions

AS3는 무엇입니까?

AS3는 Massachusetts Institute of Technology에 할당된 자율 시스템 번호(Autonomous System Number)입니다. ASN은 특정 IP 주소 집합을 제어하고 BGP(Border Gateway Protocol)를 통해 인터넷에서 트래픽이 라우팅되는 방식을 결정하는 네트워크를 식별합니다.

AS3는 몇 개의 IP 주소를 공지합니까?

AS3는 20개의 라우팅된 CIDR 접두사를 통해 1.84M개의 IPv4 주소를 공지합니다. 이 네트워크는 United States에 등록되어 있습니다.

AS3는 누가 운영합니까?

AS3는 Massachusetts Institute of Technology에 의해 운영됩니다. 이 조직은 United States에 기반을 두고 있습니다. 조직 페이지에서 모든 IP 범위 및 관련 AS를 볼 수 있습니다.

AS3는 어느 국가에 등록되어 있습니까?

AS3는 United States에 등록되어 있습니다. 이는 네트워크 운영자의 본사가 위치한 곳을 나타내지만, 해당 AS가 공지하는 IP 주소는 전 세계 사용자에게 서비스를 제공할 수 있습니다.
