AS9186 ONI Lisbon, Portugal.
Unclassified RIPE NSP
Summary
ONI (Onitelecom - Infocomunicações)
isp transit enterprise legacy
AS9186 (ONI) is held by ONITELECOM - Infocomunicações, S.A., a Portuguese telecommunications operator that sells to the business market rather than to consumers. ONI is one of Portugal's long-standing alternative operators, competing with the incumbent for enterprise connectivity, voice and managed services.
What it's used for
RIS sees 6 IPv4 prefixes covering 82,944 addresses and one IPv6 /32 (2001:a40::/32), against 29 observed BGP neighbours. That neighbour count is the useful number here. Twenty-nine is far more than an enterprise or a hosting shop needs, and far fewer than a tier-1 wholesale carrier has: it is the profile of a national alternative operator — enough peering and transit relationships to reach the Portuguese market well, but a footprint that stops at the border.
The address inventory backs that up. The bulk is a full legacy 213.58.0.0/16 plus 195.245.128.0/18, announced both as aggregates and as a few more-specifics (213.58.128.0/18, 213.58.0.0/22, 213.58.255.0/24) — the sort of selective deaggregation an operator does to traffic-engineer or to protect a block. One prefix, 38.19.200.0/22, sits outside ONI's RIPE ranges in the legacy 38.0.0.0/8 space; its sampled PTR is mail.inteltrack.pt, a Portuguese company's mail host. A customer's own domain on a customer's own block, announced by ONI, is exactly what a B2B operator's routing table looks like.
Notable
- ONI operates in the B2B segment; there is no consumer-broadband eyeball footprint visible from this AS.
- The company has changed hands several times over its life, passing through Altice and private-equity ownership before later acquisition.
- 82,944 addresses on only six prefixes means most of the space is still in large, well-aggregated legacy blocks.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

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.
