You say *Distributed*, from that I would expect that this traffic is
ingressing at multiple locations in your network?

I'd be surprised if Vodafone's domestic Italian network would spread
traffic to your ASN over multiple paths, and so if it is coming in from
multiple ingress points, you're probably looking at spoofed-source traffic.
