研究过程
[我对比了www.microsoft.com](http://www.microsoft.com/) [www.bing.com](http://www.bing.com/) 后者ip可以共用,前者无证书绑定 其中两个ip 23.12.147.174 bing的 属于 AS20940 - Akamai International B.V. 而micrsodt 属于 AS16625 - Akamai Technologies, Inc. akamai还有一个asn是 AS35994 Akamai Technologies, Inc 取了个2头的也这样 maoist2013 AS35994 Akamai Technologies, Inc ipinfo上涉及这个asn的ip都固定,无cname maoist2013 DNS over HTTPS Query Domain: [e11890.dscb.akamaiedge.net](http://e11890.dscb.akamaiedge.net/) Record Type:A (IPv4 Address)
DoH Server (optional):
e.g., https://cloudflare-dns.com/dns-query
Query DNS
Result:
{
"Status": 0,
"TC": false,
"RD": true,
"RA": true,
"AD": false,
"CD": false,
"Question": [
{
"name": "e11890.dscb.akamaiedge.net",
"type": 1
}
],
"Answer": [
{
"name": "e11890.dscb.akamaiedge.net",
"type": 1,
"TTL": 20,
"data": "2.16.6.15"
},
{
"name": "e11890.dscb.akamaiedge.net",
"type": 1,
"TTL": 20,
"data": "2.16.6.32"
}
]
}
短程似乎有些顺序
但是还是有一些这种节点
e11880.dscb.akamaiedge.net 23.222.49.231 到e11676
23.222.49.27有序
我在找断点
{
"name": "e11885.dscb.akamaiedge.net",
"type": 1,
"TTL": 20,
"data": "2.16.6.17"
},
{
"name": "e11885.dscb.akamaiedge.net",
"type": 1,
"TTL": 20,
"data": "2.16.6.16"
}、
59256+126-51256-194
1980
51256+194-49256-27
679
882开始无序
883又有序。。
AS16625有403,364个ip
假设摊给15000个
要有26段
但是事实是asn中没有这么多
ipinfo中所在段一段是19
23.222.32.0/19
共8192个ip

总结:
按照
cname
来看短程有序,长程无序
