Summary

  • The RIPE object for AS1299 attributes the routing resource to an organisation registered as Arelion Sweden AB, number 556583-2226, and the inspected APNIC records carry the same name; ARIN publishes a different label, "Arelion", at a Herndon, Virginia address with no legal suffix and no Swedish name.
  • Arelion's online terms name no universal counterparty: they apply only as indicated in a Service Order Form, refer to "the Arelion entity entering into the Order", and let the signing entity determine the governing law.

What the routing record actually registers

The AS1299 record is mostly housekeeping. Its as-name is TWELVE99; its description reads "Arelion, f/k/a Telia Carrier"; its maintainers are Twelve99-IRR-MNT and RIPE-NCC-END-MNT; its administrative and technical contacts both point at the role TRR2-RIPE (RIPE NCC aut-num AS1299). One field names a registered organisation: org, which points to ORG-TCA32-RIPE.

RIPE's own documentation is explicit about the division of labour. For an assigned aut-num, the org attribute identifies the organisation responsible for the resource; sponsoring-org is a separate, registry-synchronised attribute; and in a route object, origin identifies the originating autonomous system rather than an organisation name (RIPE NCC primary objects). Three fields, three different questions, routinely read as one.

ORG-TCA32-RIPE resolves to an org-name of Arelion Sweden AB, country SE, registration number 556583-2226 and org-type LIR. It is maintained by se-twelve99-1-MNT and RIPE-NCC-HM-MNT, and the role TRR2-RIPE is styled "Twelve99 Routing Registry" with Arelion Sweden AB in its address (RIPE NCC AS1299 search response). The organisation object was last modified on 2026-05-13; the aut-num on 2026-11-10.

Two cautions belong beside that precision. The AS1299 object contains no sponsoring-org attribute at all, which is a fact about the object and not a statement about the company. And maintenance is not ownership: a maintainer object holds the authentication methods that authorise changes to other objects, and RIPE describes maintainers as anonymous because those references alone identify no person, group or organisation (RIPE NCC database security). Whoever holds Twelve99-IRR-MNT can update the record. That settles who administers a database, not who owes a customer anything.

The Asia-Pacific side reads the same way. APNIC's organisation ORG-TCA2-AP carries the org-name Arelion Sweden AB with org-type LIR (APNIC Arelion name search), and the inspected allocation 2407:1600::/32 carries descr Arelion Sweden AB, org ORG-TCA2-AP and the status ALLOCATED PORTABLE (APNIC inet6num 2407:1600::/32). One allocation is an example, not an inventory of what the company holds.

In Virginia the registry uses a shorter name

ARIN's organisation object for handle TENS gives the organization name as "Arelion", the street address as 2325 Dulles Corner Blvd, Suite 550, Herndon, VA 20171, US, and a last modification of 2025-09-15 (ARIN organisation TENS). No AB. No Sweden. No "U.S. Inc.". The resource list under the same handle names five networks, among them 209.170.64.0/18, 209.95.128.0/19 and 2607:41C0::/32, and explains nothing about how that organisation relates to the Swedish registrant (ARIN resources under TENS).

Two documents outside the registry put a fuller name at that exact suite. The Florida Division of Corporations records ARELION U.S. INC as a foreign profit corporation with both its principal and mailing address at 2325 Dulles Corner Blvd, Ste 550, Herndon, VA 20171, in a record modified 2026-02-23 (Florida Division of Corporations). Arelion's own office directory lists "Arelion U.S. INC" at the same address (Arelion offices).

That is corroboration, not identification. Neither document mentions handle TENS, and ARIN publishes no legal suffix or company number in the object it serves. The defensible statement is narrow: the address match makes Arelion U.S. Inc. the plausible legal person behind ARIN's "Arelion", and the mapping itself is not published anywhere inspected.

The contract that declines to name a company

The registry is the easy part, because it publishes what it publishes. The contract layer is where a buyer actually stands. Arelion's online service terms page attaches its terms and SLAs to the customer's own paperwork, stating that they "will apply to the extent indicated in a Service order form"; its download link delivers version 2026v.3, and the page itself carries a last update of 2026-09-28 (Arelion online service terms page).

The downloaded document then defines its own counterparty as "the Arelion entity entering into the Order with Customer", makes the governing law depend on which entity that is, specifies Virginia law where a U.S. entity signs, and ranks the Order above both the SLA and the general terms (Arelion online terms v.3). Read together, those clauses do something specific: they move the identity question off the marketing site and into a signature block. Who owes the service, which law governs and which forum hears the argument are all decided there.

Product-level writing does not dissolve the ambiguity. The International Messaging page states that Arelion uses Telia Carrier AB, that Arelion can sign with most customer legal entities, and that new messaging customers sign a Master Service Agreement and a Service Order Form (Arelion international messaging). That is one product's undated guidance, and it names a company that appears in none of the registry objects above. A privacy contact names Arelion Sweden AB at Gustav III:s Boulevard 134, 169 70 Solna, on a page last updated 2026-04-28 (Arelion privacy policy): a data-protection address is a data-protection address, not a signature block. And the public IP address policy prints Reg no. 556583-2226 on its cover and describes Arelion as a Local Internet Registry handling IP-resource requests and RIPE database records (Arelion public IP address policy). Same number as ORG-TCA32-RIPE. Entirely different function.

What the 2021 change of control did, and did not, settle

The ownership story is documented, with one loose date in it. Polhem Infra's announcement body is dated 1 June 2021 and reports completion of the acquisition of Telia Carrier from Telia Company with full control; the same page displays a header date of 24 November 2022, which is not the transaction date (Polhem Infra completion announcement). The chief executive's post of the same day describes becoming a standalone company under a new owner, with a rebrand and new name still to come (Arelion CEO post, 1 June 2021). The rebrand release carries a 19 January 2022 dateline, and its history section dates standalone status to 1 June 2021 following the divestment (Arelion rebrand release).

Polhem's portfolio page identifies Arelion as formerly Telia Carrier and displays October 2021 as the investment date (Polhem Infra portfolio entry). Nothing inspected reconciles October 2021 with 1 June 2021. Each date belongs to its publisher until a document explains the gap.

A brand is not a party

"Polhem acquired Telia Carrier" is fair commercial shorthand for a change of control. It does not establish who became the registrant of a given resource, who is counterparty to a given contract, or what the transaction's schedules excluded. Those are three separate questions with three separate evidence trails, and only the first one has a public record anyone can read this week.

For a wholesale buyer the consequence is narrow and practical. Your counterparty is the company named in your Order and any Master Service Agreement, and your forum is the one that document selects. Brand continuity through a 2021 sale and a 2022 rename tells you the network kept running. It tells you nothing about who answers a claim. The directory entry behind this briefing, Arelion Sweden AB, is the company the routing registries name, which makes it the right card to read first and the wrong place to stop.

The discipline is two reads, not one.

Read the registry record: it names one company precisely, with a registration number you can check in public. Then read the signature block: it names the company that actually owes you.

Where the two coincide, the brand is honest shorthand for a counterparty. Where they diverge, the brand was never the point.
