Summary

Entel Chile

Chile · AI-generated

isp mobile eyeball backbone

Entel (Empresa Nacional de Telecomunicaciones) — one of Chile's largest telecom operators, running both a national mobile network and fixed broadband.

What it's used for

  • Mobile data and voice for a large Chilean subscriber base, plus fixed broadband and enterprise services.

Notable

  • A large "eyeball" network — addresses here are typically consumer mobile devices or home broadband, often behind carrier-grade NAT.
  • A leading Chilean carrier competing with Movistar (Telefónica) and Claro; also operates in Peru.

Interesting

  • Entel began as Chile's state long-distance carrier before privatization and expansion into mobile.

Classification and threat

Mobile Cellular carrier. Addresses are shared by many handsets via CGNAT.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,783 prefixes, as published 2026-10-17. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
