Summary

Arelion (formerly Telia Carrier)

Global · AI-generated

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.

Classification and threat

Transit Tier-1 or major backbone carrying other networks’ traffic.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
