Summary
Intelsat
satellite telecom enterprise global
The AS handle INTELSAT-1 is operated by Intelsat Global Service Corporation.
What it's used for
- The address space carries satellite communications infrastructure, evidenced by netnames such as
INTELSAT-ISPandUK-INTELSAT-20031126, and registrants includingIntelsat GlobalConnex Solutions (GXS)andIntelsat Global Sales & Marketing LTD. - With 195,840 IPv4 addresses announced across 97 prefixes and only 20 observed neighbours, the ratio indicates a large-scale enterprise or service provider network rather than a transit hub, consistent with a global satellite operator.
Notable
- Registrants consistently align with the announcer, listing entities such as
Intelsat,Intelsat Ripe Admin, andIntelsat GlobalConnex Solutions (GXS)across AFRINIC and RIPE regions. - Intelsat is a Luxembourgish communications satellite services provider that has undergone significant corporate restructuring and rebranding in recent years.
- The inventory is geographically diverse, spanning AFRINIC (41.194.0.0/18), RIPE (82.206.128.0/18), and ARIN (66.36.192.0/19) regions, reflecting a global operational footprint.

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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
