VALICOM-AS is operated by Minhocom, Gestao de Infraestuturas de Telecomunicacoes EIM.

What it's used for

  • The address space carries business and infrastructure traffic, evidenced by the netname VALICOM-NET and reverse DNS entry mail.copper-alembic.com.
  • The AS announces 512 IPv4 addresses across 1 prefix (195.54.168.0/23) and maintains 1 observed neighbour, indicating a small-scale access or business network rather than a transit provider.
  • Traffic from this AS consists of corporate and infrastructure endpoints for a telecommunications infrastructure management company based in Valença, Portugal.

Notable

  • The registrant MINHOCOM, Gestao de Infraestuturas de Telecomunicacoes EIM matches the AS holder, confirming consistent ownership of the announced space.
  • The inventory consists of a single contiguous /23 block, representing a compact and focused address allocation for the operator's infrastructure.

Reputation

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
