我有一点困惑。
我想知道当前 ASN(及其相应的前缀)从什么时候开始实行的。
当我看到 team-cymru 上的例子时(http://www.team-cymru.com/IP-ASN-mapping.html) 我懂了:
$ whois -h whois.cymru.com " -v 216.90.108.31 2005-12-25 13:23:01 GMT"
AS | IP | BGP Prefix | CC | Registry | Allocated | Info | AS Name
23028 | 216.90.108.31 | 216.90.108.0/24 | US | arin | 1998-09-25 | 2005-12-25 13:23:01 GMT | TEAMCYMRU - SAUNET
You may also query for some basic AS information directly:
$ whois -h whois.cymru.com " -v AS23028"
AS | CC | Registry | Allocated | AS Name
23028 | US | arin | 2002-01-04 | TEAMCYMRU - SAUNET
那么,ASN23028
和 BGP 前缀216.90.108.0/24
是在 1998 年还是 2002 年分配的?
谢谢!
