目前中国铁通已成为中国移动的子公司,并改名中移铁通,两家公司原有网络已完成割接合并,建议将铁通的 IP 地址信息合并至中国移动,不知是否可行?
已知的 AS 信息:
中国移动:

AS9808        CMNET-GD Guangdong Mobile Communication Co.Ltd., CN
AS24311       CNGI-CMNETV6-AS-AP China Mobile Communications Corporation IPv6 network, CN
AS24400       CMNET-V4SHANGHAI-AS-AP Shanghai Mobile Communications Co.,Ltd., CN
AS24444       CMNET-V4SHANDONG-AS-AP Shandong Mobile Communication Company Limited, CN
AS24445       CMNET-V4HENAN-AS-AP Henan Mobile Communications Co.,Ltd, CN

AS138407      CMNET-GZIDC-CN The Internet Data Center of Guizhou Mobile Communication Company Limited, CN

中移铁通:

AS9394        CTTNET China TieTong Telecommunications Corporation, CN
AS24138       CRNET_BJ_IDC-CNNIC-AP China Tietong Telecommunication Corporation, CN

AS45069       CNNIC-CTTSDNET-AP china tietong Shandong net, CN

不知是否有遗漏,仍然需要检查一下。

从AS连接状态来看,铁通和移动的分界线仍然比较明显。我本机有联通线路,测试了几个铁通地址,两网互联节点很少,且部分地址依然会绕电信。
在现阶段,个人更加倾向于分开处理两个运营商的IP,将合并的选择权交给用户。

看来网络合并还没有调整完,那么先不合并了……
P.S. “我本机有联通线路” <- 是有移动线路吗?

有四条独立线路:电信、联通、移动、教育网

P.S. 如果从移动线路发起测试,不会饶到其他运营商

差点忘记了 mirrors 上写过有四个出口 😂
照说测试移动铁通互联性只要通过移动出口测铁通就行了……?

目前的线路是这样的:
“联通->电信->铁通”

联通和移动之间有直连。如果移动和铁通已完美合并,按说不应该经过第三个运营商,即期望的路径为:
“联通->(移动->铁通)”

综上,从线路的实际表现来看,铁通更像是一个独立的运营商,而非与移动成为了某种整体。

重新申请进行合并:从 bgp.he.net 提供的路由信息来看,现在(2020-06-12)铁通主干网络 AS9394 只有一个上游,也就是中国移动的骨干网络 AS9808 :

可以认为网络已经合并了。
@gaoyifan 可否再考虑一下?谢谢!
Edit:又确认了一下我在顶层贴的全部中国铁通 AS 号码,已经全部单一接入到中国移动的各 AS 中

HE的数据只是铁通向国际方向发送的宣告,国内部分的宣告可能由于community控制等原因,并不会到达HE,因此没有被画出来

比如:
联通-铁通(经过电信)

Hi @gaoyifan ,更正一下,4837->9394 其实是直接互联的,202.97.10.236 是9394的设备,不是4134的设备,该设备同时在北京NAP接入了4837与4134处理IN流量,原因该9394的设备只有In负载,只负责向其他ISP宣告前缀,不处理Out流量,故该设备没有其他ISP的路由表,默认路由的source ip是电信的IP,所以有看似绕行电信的情况出现。
