Summary

Sure South Atlantic

Falkland Islands (Malvinas) · AI-generated

mobile residential telecom falkland

FALK is operated by Sure South Atlantic Limited.

What it's used for

  • The address space carries mobile and broadband subscriber traffic, evidenced by reverse DNS entries such as isp14255.horizon.net.fk and isp9254.horizon.net.fk.
  • The AS announces 3584 IPv4 addresses across 3 prefixes with only 1 observed neighbour, a ratio characteristic of an access network serving local subscribers rather than a transit provider.
  • Traffic consists of mobile network services, broadband, fixed line, and enterprise solutions provided to consumers and businesses in the Falkland Islands, Ascension, and St Helena.

Notable

  • All registrants for the announced prefixes are listed as Sure South Atlantic Limited, matching the AS holder.
  • Sure South Atlantic operates as the primary mobile network in the Falkland Islands under PLMN 750001, providing telecommunications services across three South Atlantic islands.
  • The inventory consists of three IPv4 prefixes with no IPv6 prefixes announced.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
