Telia · Denmark
Telia is a mobile operator in Denmark whose parent group the registry records as Norlys. Its mobile network is carried by AS3308, registered to Norlys Telco A/S under the name TELIANET-DENMARK, and a second ASN, AS12435, is registered to the same company. Telia Denmark uses MCC 238 with MNC 20.
Autonomous systems
Holder names and prefix counts come from the RIPE NCC's RIPEstat Data API, fetched on 2026-09-06. Role and confidence come from the evidence linked in each row; "confirmed" means a PeeringDB or RIPEstat record, or the operator's own site, names the operator.
Mobile network codes
The MCC identifies the country and the MNC identifies the operator inside it. Together they appear in the IMSI of every SIM on the network and in device diagnostics; they are how a handset knows which network it is on.
About Telia
The registry records two ASNs for Telia in Denmark, both held by Norlys Telco A/S. AS3308, registered as TELIANET-DENMARK, is the confirmed mobile-role network, and at the last probe it announced 23 IPv4 prefixes against 7 IPv6 prefixes; PeeringDB carries the record under the Norlys name pointing at the telia.dk website. AS12435, registered as TELIAMOBILE-DK, is marked mobile on a name match alone, announced no prefixes at the last probe and has no PeeringDB record. The registry lists 5G among the generations and has no confirmed entry for earlier ones.
An address whose origin ASN is 3308 is routed by the Danish network trading as Telia and registered to Norlys Telco A/S, so the operator brand and the registered holder name differ. That network also carries fixed and business customers, so an address there could be mobile, fixed or enterprise, and the ASN on its own does not settle which. Radio access is shared with Telenor through TT-Netvaerket P/S under the separate code 238-66, which does not change whose ASN the traffic leaves through. AS12435 announces nothing and will not appear as a traffic origin.
Research note. Telia Danmark was sold by Telia Company to Norlys; the deal closed 2/3 April 2024 and RIPE now registers the former Telia ASNs to Norlys Telco A/S. telia.dk returns 403 to fetchers and its customer-service paths 301-redirect to shop.norlys.dk, so the brand appears to be migrating to Norlys; PeeringDB AS3308 record is named 'Norlys' with website telia.dk. 238-20 is the operational Telia network; 238-96 (test, withdrawn) and 238-30 (now Interactive digital media GmbH, 'former Telia') were dropped. Shared RAN with Telenor is TT-Netvaerket P/S (238-66). AS3308 is announced (~1000 IPv4 prefixes, NSP); AS12435 TELIAMOBILE-DK is unannounced and not in PeeringDB. Only 5G is stated on the reachable Norlys page; 4G exists per the Wikipedia band list (LTE 800/1800/2600) but no operator page confirming 4G could be fetched.
Checking whether an IP belongs to Telia
Look up the origin ASN of the address and compare it with the table above. RIPEstat answers for any address, and the RADB whois mirror lists the routes registered under an ASN.

What is Telia Denmark's ASN?
The registry records AS3308, registered to Norlys Telco A/S as TELIANET-DENMARK, as the ASN carrying Telia's Danish network. A second ASN, AS12435, named TELIAMOBILE-DK, is registered to the same company but announced no prefixes at the last probe.
What is the MCC/MNC of Telia Denmark?
Telia Denmark uses MCC 238 with MNC 20, written 238-20, as its operational network code. The shared radio network operated with Telenor through TT-Netvaerket P/S holds the separate code 238-66.
Is an IP from AS3308 a mobile IP?
AS3308 is the ASN the registry marks as carrying Telia Denmark's mobile network, so an address originating there is routed by that operator. The same ASN also carries fixed and business traffic, so it can be mobile, fixed or enterprise; the origin ASN does not decide it.
