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 Tigo

Tigo is the consumer brand of Telefonica Celular de Bolivia S.A., a Bolivian mobile network operator owned by Millicom. Its mobile network is carried on AS27882, which the registry confirms in a mobile role. Tigo holds MCC 736 with MNC 03, and the registry lists 4G LTE for the network.

The registry records a single ASN for Tigo, AS27882, registered to Telefonica Celular de Bolivia S.A. and confirmed in a mobile role. At the last probe it announced 352 IPv4 prefixes against 159 IPv6 prefixes, so roughly one prefix in three is IPv6. PeeringDB lists the network as Telefónica Celular de Bolivia and classifies it as Cable/DSL/ISP, a category that reflects AS27882 carrying Tigo's fixed customers alongside its mobile ones.

An address whose origin ASN is AS27882 is routed by Tigo Bolivia. The mobile role is documented, so a match places the address on the operator's network, though the same ASN also carries fixed broadband, which the PeeringDB Cable/DSL/ISP classification points to. An origin lookup on its own cannot separate a handset from a home connection here, and you need something beyond the ASN to make that call. No other ASN in the registry belongs to Tigo Bolivia.

Research note. Legal name Telefónica Celular de Bolivia S.A. (Telecel). PeeringDB aka 'Tigo Bolivia', website tigo.com.bo, info_type Cable/DSL/ISP; AS27882 carries the whole Tigo Bolivia network (mobile + fixed). tigo.com.bo returned 403 to fetch; es.wikipedia states 4G nationwide and 5G 'working to implement soon' with no launch date, so 5G not listed. Millicom ownership per Wikipedia (Millicom 100%).

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.
