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 3

3 is a mobile operator in Denmark, run under CK Hutchison Group Telecom, part of CK Hutchison, which uses the 3 brand in Italy, Sweden, Denmark, Austria and Ireland. Its mobile traffic is carried by AS44034, registered to Hi3G Access AB, and it uses MCC 238 with MNC 06.

The registry records one ASN for 3 in Denmark, AS44034, held by Hi3G Access AB and confirmed as the mobile-role network. That ASN is registered in Sweden and is the only aut-num under its RIPE organisation object, and PeeringDB gives it the aka '3 Sweden / 3 Denmark', so Danish 3 mobile traffic shares a Swedish-registered ASN. No separate Denmark-registered Hi3G ASN exists in the RIPE database. At the last probe AS44034 announced 10 IPv4 prefixes against 3 IPv6 prefixes, and PeeringDB names it Hi3G Access AB with the network type Cable/DSL/ISP.

An address whose origin ASN is 44034 is routed by Hi3G, the operator behind the 3 brand, and the registry files that ASN under a mobile role, with 4G LTE and 5G recorded as the generations 3 runs in Denmark. The ASN alone does not tell you which country the subscriber is in, because the same number covers 3 in Sweden as well as in Denmark. The Danish legal entity is Hi3G Denmark ApS, CVR 26123445, but the registry has no Denmark-only ASN to separate the two markets by origin.

Research note. No candidates were supplied; found via PeeringDB aka search. AS44034 is registered to Hi3G Access AB (Sweden, ORG-HAA1-RIPE) and is the only aut-num under that org in the RIPE DB; PeeringDB lists its aka as '3 Sweden / 3 Denmark', so Danish 3 mobile traffic shares this Swedish-registered ASN. No separate Denmark-registered Hi3G ASN exists in the RIPE DB. Legal entity from 3.dk footer: Hi3G Denmark ApS, CVR 26123445.

Questions

What is 3 Denmark's ASN?
The registry records AS44034, held by Hi3G Access AB, as the ASN carrying 3's mobile network in Denmark. It is registered in Sweden and shared with 3 Sweden. No ASN registered in Denmark to Hi3G exists in the RIPE database.
What is the MCC/MNC of 3 Denmark?
3 Denmark uses MCC 238, the country code for Denmark, with MNC 06, so the full network code is 238-06. The registry records that one code for the operator and no others.
Is an IP from AS44034 a mobile IP?
The registry marks AS44034 as 3's mobile-role ASN, so an address originating there is routed by the operator's network. The same ASN also carries 3 Sweden, so the origin ASN identifies the operator group rather than the country the address is used in.

ASN and prefix data describe how the operator's networks are registered and announced. They do not identify an individual subscriber or where a device is, since carriers route traffic from many areas through shared gateways.
