Summary

Telesat

United States of America · AI-generated

satellite telecom business

The AS handle LORAL-CYBERSTAR is held by Telesat Network Services Inc.

What it's used for

  • The address space carries satellite communications infrastructure, evidenced by netnames such as LORAL-SKYNET-AR1, LORAL-SKYREACH, and TELESAT.
  • The AS announces 18,944 IPv4 addresses across 12 prefixes with only 2 observed neighbours, indicating a specialized satellite network rather than a general transit or access provider.

Notable

  • Registrants consistently identify as Telesat Network Services Inc or Telesat, aligning with the current operator identity.
  • Telesat Network Services Inc is the successor to Loral Space & Communications, which was acquired by Telesat in 2017, explaining the retention of "Loral" in the AS handle and netnames.
  • The inventory is dominated by the 24.142.0.0/16 range, specifically the LORAL-SKYREACH netname, alongside a smaller block under LORAL-SKYNET-AR1.

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: 454 networks and 1,847 prefixes, as published 2026-11-11. 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.
