AS544

AS544 is a legacy autonomous system registered under RIPE NCC to Telia Finland Oyj, the Finnish arm of Telia Company AB, the publicly traded Nordic/Baltic telecom group (Nasdaq Stockholm and Nasdaq Helsinki). RIPE's authoritative RDAP record names the resource "Telia-international-network" and shows a top-level registration event dated 2002-08-26, with the record last changed 2026-05-04. Despite belonging to an active, well-resourced operator, AS544 itself is currently dormant: RIPEstat, CAIDA ASRank, and bgp.he.net independently agree it announces zero IPv4 and zero IPv6 prefixes, carries a singleton customer cone (itself, with no downstream prefixes or addresses), and has not been visible in the global routing table since March 2022. CAIDA ranks it 79,459 globally, reflecting this inactivity. The RIPE object still carries BGP community definitions for AS544 transit customers and a stated RPKI-reject policy, evidence of a once-active production role that PeeringDB's listing (facility presence in Denmark, Sweden, Norway, Finland, and Estonia; thousands of prefixes) appears to describe in aggregate or historical terms rather than AS544's present live state. No public abuse or hijack signal was found against Spamhaus ASN-DROP or NANOG/seclists archives as of 2026-07-11.

Operator

Telia Finland Oyj (RIPE-registered holder org; part of Telia Company AB group, historically linked to predecessor Sonera Corporation) [Confirmed] — https://rdap.db.ripe.net/autnum/544

Country / RIR

Finland, RIPE NCC [Confirmed] — https://stat.ripe.net/data/as-overview/data.json?resource=AS544

Allocated

2002-08-26 (RIPE RDAP autnum top-level "registration" event); last changed 2026-05-04 [Confirmed, corroborated by three independent research angles] — https://rdap.db.ripe.net/autnum/544

AS name

"Telia-international-network" (current RDAP name); one WebSearch snippet associates the number historically with "SONERA-FUNET-TRANSIT," a Finnish academic-network name predating Telia's acquisition of Sonera — treated as stale, not current [Likely current name Confirmed; historical alias Unknown] — https://rdap.db.ripe.net/autnum/544, https://www.bgplookingglass.com/list-of-autonomous-system-numbers

Org status

Active — RIPE RDAP status "active"; holder org Telia Finland Oyj is part of publicly traded Telia Company AB (Nasdaq Stockholm, also listed Nasdaq Helsinki), a major Nordic/Baltic telecom group [Confirmed] — https://rdap.db.ripe.net/autnum/544

Abuse contacts

abuse@telia.com (RDAP group TR889-RIPE) and abuse@telia.fi (RDAP group RSF6-RIPE)

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-07-11 — AS544 does not appear on the live Spamhaus ASN-DROP feed, and no NANOG/seclists.org hijack or route-leak reports were found [Confirmed absence in Spamhaus; Likely for NANOG search coverage] — https://www.spamhaus.org/drop/asndrop.json, https://seclists.org/nanog/

Network & routing

Network type

shared Nordic/Baltic peering ASN for Telia Company's national operating entities (Sweden AS3301, Finland AS1759, Norway AS25400, Lithuania AS8764, Estonia AS3249 route/peer behind it per PeeringDB) [Confirmed] — https://www.peeringdb.com/net/39208

Routing status

dormant/legacy — 0 IPv4 and 0 IPv6 prefixes announced as of 2026-07-11; not visible in the global routing table since 2022-03-01 [Confirmed] — https://stat.ripe.net/data/announced-prefixes/data.json?resource=AS544, https://bgp.he.net/AS544

AS rank / cone

CAIDA ASRank 79,459; customer cone = singleton (1 ASN, 0 prefixes, 0 addresses); zero upstreams and zero peers observed [Confirmed] — https://api.asrank.caida.org/v2/restful/asns/544

Peering

PeeringDB lists a "Restrictive" policy with ~5,000 IPv4 / ~1,000 IPv6 prefixes and facility presence in Denmark, Sweden, Norway, Finland, and Estonia — this conflicts with the live zero-announcement routing status confirmed via RIPEstat/CAIDA, so the PeeringDB prefix/facility figures are treated as stale or aggregated rather than AS544's present live state

[Likely, flagged as conflicting] — https://www.peeringdb.com/net/39208

RPKI

not independently assessable — RIPE RDAP remarks state AS544 "is matching RPKI validation state and reject[s] invalid prefixes," but this is a stated policy, not a computed result, since no prefixes are currently announced [Likely] — https://rdap.db.ripe.net/autnum/544

Analyst note

a legacy low-numbered ASN that is currently dormant (last globally visible 2022-03-01) despite belonging to a large, active operator; PeeringDB's listed prefix/facility counts read as stale relative to live routing data, and no computed RPKI validation state exists absent live announcements.
