Summary
MEO (Altice Portugal) — International
transit isp legacy
MEO-INTERNACIONAL is the international/wholesale carrier arm of MEO, the Portuguese incumbent operator (formerly Portugal Telecom, now Altice Portugal). It is not MEO's consumer broadband network.
What it's used for
- International transit and wholesale IP interconnection: carrying traffic between Portugal and the rest of the world, and reselling transit to downstream networks, particularly on Portugal's submarine-cable routes to Europe, Africa and the Americas.
Notable
- The evidence is in the ratio, not the size. The AS announces only about 11,000 IPv4 addresses across three prefixes, yet has 136 observed BGP neighbours. A network that small with that many adjacencies is selling transit, not hosting content or numbering subscribers.
- Sampled reverse DNS resolves to
lis1-cr1.cprm.net— a Lisbon core router. Thecprm.netdomain is Companhia Portuguesa Rádio Marconi, the historic Portuguese international-communications company absorbed into Portugal Telecom; the backbone naming outlived the brand. - The
195.8.0.0/19prefix has been announced from this AS since at least 2000.
Interesting
- MEO's retail eyeball network is carried on other ASNs. Geolocating this space to Portuguese households would be wrong — these are backbone and interconnect addresses.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,772 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.
