Hello NANOG,I noticed that more than 3K prefixes are with 2 Origin ASes.Are they the simplest cases of anycast? Or they are mainly due to misconfiguration?
The third (and probably more likely) option is that the prefixes are advertised by two providers as the customer wants redundancy with their own IP space, but does not have a public ASN. Ie. the customer has a circuit and possibly a BGP feed to two different providers.
