Summary

Comune di Milano

Italy · AI-generated

government municipal italy

COMUNEMILANO-AS is operated by Comune di Milano, the municipal government of Milan.

What it's used for

  • The space carries the administrative network of the City of Milan, identified by the netname IT-COMUNEMILANO-20030612 and registrant Comune di Milano.
  • The AS announces a single IPv4 prefix, 217.31.112.0/20, comprising 4096 addresses, with 0 IPv6 prefixes.
  • With only 2 observed neighbours, the low neighbour count relative to the address block suggests a small, self-contained internal network rather than a transit or large-scale access provider.

Notable

  • The RDAP registrant Comune di Milano matches the AS holder name exactly, confirming direct ownership.
  • The address inventory consists of a single contiguous /20 block, indicating a simple, unified allocation for the municipality's infrastructure.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
