Dear colleagues,

I
​ ​
have seen that some operators in EU have different ASN for their services, one for transit, another for their subscribers and one for their datacenter services.

As long as some of the spam protection services treat ASNs differently, is there any relation between having different ASN and protecting their infrastructure's ASN to show up in lists like this:

​

​As a network/security administrator, do you drop/inspect/throttle connection based on ASN?
