Re: Spamhaus flags any IP announced by our ASN as a criminal network

I do not believe ASN sharing is illegal or prohibited, it's not prohibited
in LACNIC and in APNIC policy I also could not find anything about ASN
sharing, only

APNIC policy states:
"2.3. Autonomous System (AS)
An Autonomous System (AS) is a connected group of one or more IP prefixes
run by one or more network operators under a single and clearly defined
routing policy.
2.3.1. Autonomous System Number (ASN)
An Autonomous System Number (ASN) is a unique two- or four-byte number
associated with an AS. The ASN is used as an identifier to allow the AS to
exchange dynamic routing information with other Autonomous Systems."

Nothing prohibiting ASN sharing and 2.3 specifically states "run by one or
more network operators... single routing policy"

George

Several Huize ASNs, e.g. AS47158 and AS141011, were revoked due to RIR
policy violations, which include prohibited sharing of ASNs with third
parties, IP hijacking, and malicious path prepending.

Given this history, it is not surprising that Spamhaus would blacklist
IP addresses associated with their ASN. In my opinion, such action is
well-justified.
