Summary

Telefónica Móviles El Salvador

El Salvador · AI-generated

isp mobile legacy

The Movistar mobile network in El Salvador.

What it's used for

  • Mobile and fixed access, and the reverse DNS labels which is which. Names run under telefonica-ca.net with a role in front: sv-mobile-apn-4 for the mobile packet gateway, sv-metro-1 for metro access, and a plain ip-sv for the rest.

Notable

  • 3,072 addresses across eleven prefixes, ten of them /24s. Two observed BGP neighbours, no IPv6 announced.
  • Two blocks in 66.119.92.0/24 and 66.119.94.0/24 are registered as TCOAM-SALVADOR-6 to Telefónica, from a different registry than the rest.
  • The 190.57 blocks carry LACNIC-style netnames that are literally the address range they cover, such as 190.57.64.0 - 190.57.127.255, rather than a company abbreviation.

Interesting

  • One block's reverse DNS is labelled ip-gt rather than ip-sv. The domain is telefonica-ca.net, where ca is Central America, and the operator ran its networks in several countries off shared regional infrastructure — so a Guatemala label turns up inside the El Salvador AS.
  • apn in sv-mobile-apn-4 is the Access Point Name, the gateway a handset asks for by name when it opens a data session. It is the seam between the mobile network and the internet, and numbering them means there is more than one, usually because different services get different treatment on the way out.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
