AS7589 TWELVE99-ENTERPRISE-SERVICES Arelion Sweden AB

TWELVE99-ENTERPRISE-SERVICES, a small downstream AS of Arelion Sweden AB — the

global carrier formerly known as Telia Carrier, whose backbone is

[AS1299](https://asn.ipinfo.app/AS1299) and whose network brand is Twelve99.

What it's used for

• Enterprise service delivery behind the Arelion backbone. Its routing policy is explicit: it accepts everything from AS1299 and announces only itself back, so it is a customer-facing leaf of the carrier rather than a transit network in its own right.
• It announces just two /24s, carved out of Arelion's own APNIC allocation, so the addressing is the carrier's rather than a third party's.

Notable

• An IP here is carrier-assigned enterprise space, not a residential or mobile subscriber and not general-purpose hosting. There is no reverse DNS on the sampled addresses, which limits how confidently the specific use can be called.
• The Asia-Pacific registration on a Swedish carrier's AS is not a contradiction: Arelion holds address space in every region it operates in, and this block sits in APNIC's 202.163.0.0/19 allocation to the company.

Interesting

• The Twelve99 branding is a nod to the AS number of the backbone itself, one of the more recognisable numbers on the internet — while this AS, a much lower number, is the quieter one attached to it.
