bgp - IP 到 ASN 映射算法

有没有简单的方法可以将给定的 IP 地址映射到相应的 ASN 号？例如：

ping 找出 IP 地址：

whois 查找 ASN 号：

所以这种情况下的映射是130.59.108.36（IP）-> 559（ASN）。简单的。但是，如果我想使用来自区域互联网注册机构的公开可用信息创建自己的本地地图服务，该怎么办？所以，对于上面的例子，就是这个列表，对吧？

并且找到匹配的条目也不是问题：

但是我如何从上面的行中获取 ASN 号？这两个信息是如何联系在一起的？

提前感谢您的回复！

networking - BGP 公告？

谁能解释 BGP 中的公告是如何工作的？我知道 BGP 找到了到目标网络的最短/成本最低的路径，但我也在某处读到它宣布了这些路径。这是真的吗，它究竟是如何宣布路线的？

configuration - Configuring BGP Neighbors In Quagga

I am trying to run Quagga on a couple of connected VMs and am confused about how to write the neighbor command in the bgpd.conf configuration file. All my queries are about the following specific statement of neighbor specification:

neighbor peer remote-as asn

What should I provide for the 'peer' IP value? Say I am configuring a VM A which is many hops away from a neighbor B (lets assume same AS number). So when I add neighbor B in the bgpd.conf configuration file, which particular interface IP of B should be added as the peer IP in the configuration file.

I am seeing that for some interface IPs the connection is not getting established and for some it is. So I want to know theoretically which of the interface IPs should be specified.

I did a lot of Google study but no ones clear about this. Please help.
