Transit RIPE NSP
Summary
Arelion (formerly Telia Carrier)
tier-1 transit backbone
Arelion — formerly Telia Carrier — operates one of the world's top-ranked
Tier 1 backbones (TWELVE99, a nod to the AS number).
What it's used for
- Global IP transit and wavelength/backbone services sold to ISPs, content networks, and enterprises worldwide.
- Consistently ranked at or near the top of global IP-transit reachability rankings by connected networks.
Notable
- A Tier 1: it reaches the entire internet through settlement-free peering and buys transit from no one.
- Low announced IPv4 count is normal for a pure transit carrier — it moves other networks' traffic rather than hosting end users.
Interesting
- Divested by Telia (sold to the Swedish investor Polhem Infra) in 2021 and rebranded from Telia Carrier to Arelion in January 2022. It's often used as a reference backbone in latency and routing studies.
