461,312 addresses in 263 announcements, under a netname dated June 1993 — the oldest in this sweep.

What it's used for

  • Carrier connectivity in Italy. 461,312 addresses in 263 IPv4 prefixes, two IPv6 prefixes, and one observed BGP neighbour.

Notable

  • 145.230.128.0/17 and 145.230.32.0/19 carry the netname DE-VODAFONE-19930609.
  • Other netnames run DE-VODAFONE-971003, DE-VODAFONE-20100721, DE-VODAFONE-20101209 and DE-VODAFONE-20111223.
  • Every netname begins DE-, while the holder is Fastweb SpA and the blocks are announced from Italy.
  • The IPv6 side is two /44s, 2a01:818:1000::/44 and 2a01:818:1060::/44.
  • Eighteen sampled addresses were queried and none returned a name.

Interesting

  • A 1993 allocation date is the earliest anywhere in this range. It predates the commercial web and most of the companies in this number range, and it is attached to a block that is still carrying traffic thirty-three years later. Address registrations outlive nearly everything else in the industry.
  • The country prefixes disagree with reality. German netnames on Italian announcements are what happens when a multinational holds its address space centrally and lets each national operating company announce whichever pieces it needs. Reading netname prefixes as geography fails on exactly these networks — the large ones.
  • Two /44s of IPv6 against 461,312 IPv4 addresses is a striking imbalance for a carrier this size, and the opposite of the pattern in the smaller networks nearby, where IPv6 holdings dwarf IPv4.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,771 prefixes, as published 2026-10-15. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
