MTS Belarus · Belarus
MTS Belarus is a mobile operator in Belarus, held as a joint venture between Beltelecom with 51 percent and Russia's MTS PJSC with 49 percent. The registry records one confirmed mobile ASN, AS25106, held by MTSBY-AS Mobile TeleSystems JLLC, and one network code pair, MCC 257 with MNC 02. Its site is mts.by.
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 MTS Belarus
The registry holds one ASN for MTS Belarus, AS25106, registered to MTSBY-AS Mobile TeleSystems JLLC and marked as the operator's mobile network with confirmed confidence. At the last probe it announced 194 IPv4 prefixes and 34 IPv6 prefixes, so IPv6 accounts for a visible share of the announced blocks. PeeringDB records the ASN under the name Mobile TeleSystems and points it at mts.by, without setting a network type. The 4G and 5G radio the operator sells runs over the state wholesale network beCloud, AS60330, which the registry does not list as an MTS ASN.
An address whose origin ASN is AS25106 is routed by MTS Belarus, and the registry marks that ASN as the operator's mobile network. The record does not divide the ASN by access type, so the same origin can carry fixed and business connections alongside handset traffic, and the origin identifies the operator rather than the kind of line. An address originating on beCloud's AS60330 belongs to the wholesale infrastructure operator, even where the subscriber using that radio is an MTS customer.

PeeringDB record for AS25106 names 'Mobile TeleSystems' with website http://www.mts.by. Ownership split (Beltelecom 51% / MTS PJSC 49%) is stated on Wikipedia only; the ministry page does not state shareholders. None of the 13 asn.txt candidates belong to MTS; all rejected as keyword matches. 4G and 5G radio infrastructure is provided by the state wholesale operator beCloud (AS60330 BCTBY-AS); mts.by news states 5G access for MTS subscribers from April 2026. Operator site refused connections from this location; facts taken from search-indexed content of the cited mts.by URLs.
