About this network

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.
