AS8903 — AS8903 LYNTIA NETWORKS S.A.

AS8903 announces 113 IPv4 prefixes covering 164,352 addresses and 14 IPv6 prefixes.

About this network

AS8903 is the peering and transit AS of Lyntia Networks S.A., Spain's largest neutral wholesale fibre operator, run from Alcobendas (Madrid) with a nationwide network of tens of thousands of route-kilometres built largely along electricity and gas rights-of-way.

What it's used for

• Wholesale carriage: dark and lit fibre, transit and capacity sold to other operators, ISPs and large enterprises rather than to end users.
• Around 173k IPv4 addresses over 110 prefixes plus IPv6, with roughly 105 observed BGP neighbours. The neighbour count is the real size signal — it is the shape of a carrier, not of an eyeball network.

Notable

• The AS carries a visible BT España inheritance. Sampled rDNS on its anchor block 212.49.128.0/18 returns popmbta1-feth0-0-0.net.bt.es, and the AS is still listed in the AS-BT-ES ("BT Global Spain customers") route set. The AS number was allocated in 1998, and the space and naming came across with the business.
• Ownership has changed hands repeatedly among infrastructure funds — Antin, then a consortium of AXA IM Alts and Swiss Life in 2023, with Morrison & Co taking a third in 2024. The network kept running throughout; only the cap table moved.

Interesting

• Because Lyntia sells wholesale, an address here often fronts someone else's service. Do not read a Lyntia IP as a Lyntia end user.
