Summary
Colombia Telecomunicaciones (Movistar / Tigo)
isp legacy
Colombia Telecomunicaciones S.A. ESP ("Coltel") is one of Colombia's largest
telecom operators, long known to consumers by the Movistar brand. As of early
2026 the company is owned by Millicom, the parent of Tigo, after Millicom
bought out both Telefónica's controlling stake and the Colombian government's
minority stake.
What it's used for
- Fixed broadband and internet access for Colombian households and businesses.
- Backbone and transit for the operator's own mobile and fixed services.
Notable
- Announces roughly 3.1 million IPv4 addresses, making it one of the largest eyeball networks in this ASN range and a major destination for content delivered into Colombia.
- Coltel descends from Colombia's state telephone company, which is why the government held a stake in it until the Millicom buyout.
Interesting
- The Tigo and Movistar merger puts roughly 41 million mobile lines under one owner, close to market leader Claro, so the branding and network attribution around this AS may keep shifting as the two operations integrate.
