在互联网上,路由以前缀的形式宣告:一个自治系统通过 BGP 告诉邻居,它可以投递发往例如 62.103.0.0/16 的流量。本工具在我们每日更新的全球路由表副本中查找前缀,并显示三项内容:

精确宣告:哪个 AS 正好起源这个前缀。存在多个起源(MOAS)对任播服务和某些多归属网络来说是正常的,其他情况下则值得怀疑。
覆盖路由:包含该前缀、但不那么具体的宣告。流量遵循最具体的路由;当更具体的路由消失时,覆盖路由才起作用。
更具体的路由:前缀内部的宣告,可能属于其他网络(客户,或者劫持)。

对每条宣告的路由,还会检查 RPKI:是否有 ROA 授权其起源 AS。

该路由表来自 APNIC 路由收集器的视角。全球路由表的大部分从任何地方看都一样,但在到达收集器之前被过滤掉的路由不会出现。

常见问题

为什么我的 /24 不显示,而 /16 却显示?

您的地址是作为更大地址块的一部分宣告的,没有人单独宣告这个 /24。这是大多数运营商客户的正常情况。

什么是更具体前缀劫持?

有人在您的地址空间内宣告一个更长的前缀。由于路由器优先选择最具体的路由,流量就会流向对方。设置严格最大长度的 RPKI 会使这类宣告无效。

可以输入单个地址吗?

可以。工具会显示包含该地址的最具体宣告路由。
