Unclassified RIPE
Summary
ANACOM
government regulatory ipv6
The AS handle ANACOM is held by ANACOM (Autoridade Nacional de Comunicações).
What it's used for
- The address space carries a single IPv6 prefix,
2a0b:94c0::/48, with no IPv4 addresses announced. - The inventory consists of 1 IPv6 prefix and 0 IPv4 prefixes, observed against 3 routing neighbours, indicating a small-scale internal network for a specific organisation rather than a transit or access provider.
- Traffic from this AS represents the internal communications infrastructure of Portugal's national regulatory authority for the communications sector.
Notable
- The registry holder is listed as anacom Autoridade Nacional de Comunicacoes (Anacom), which aligns with the AS handle.
- The address inventory is minimal, consisting solely of one /48 IPv6 block, which is typical for a government agency maintaining a dedicated, non-public network presence.

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
