Summary

United States of America · AI-generated

satellite broadband corporate infrastructure

SPACEX is the autonomous system for Space Exploration Technologies Corporation.

What it's used for

  • The address space carries Starlink satellite broadband infrastructure, evidenced by reverse DNS entries such as customer.lsancax1.pop.starlinkisp.net and customer.sea.pop.starlinkisp.net.
  • The AS announces 4608 IPv4 addresses across 10 prefixes while maintaining only 6 observed neighbours, a ratio indicative of a large-scale access or eyeball network rather than a transit provider.

Notable

  • Registrants for the majority of prefixes are Space Exploration Technologies Corporation, with netnames including SPACEX-STARBASE, SPACEX, and SETC-3.
  • The prefix 173.250.192.0/22 is registered to American Registry for Internet Numbers with the netname NET173, differing from the primary registrant.
  • The inventory consists of a mix of /22, /23, and /24 blocks, with the largest allocations being 66.9.188.0/22 and 173.250.192.0/22.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-28, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation

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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
