business satellite defense spatial

EWI-ASN-1 is held by Vantor Parent Inc.

What it's used for

  • The address space carries corporate infrastructure for a spatial intelligence and defense technology firm, with netnames MAXAR-PUBLIC and MAXAR-205-166-175-0-24 indicating legacy branding.
  • The inventory consists of 7 IPv4 prefixes totaling 2304 addresses, observed against 6 neighbours, suggesting a small-scale corporate network rather than a transit or access provider.

Notable

  • Registrants for the majority of prefixes are Vantor Parent Inc., while the prefix 173.242.16.0/24 is registered to Lunavi, Inc.; Network Operations Center with netname GHD-173-242-16-0-1.
  • The operator was formerly known as Maxar Technologies, which rebranded to Vantor in October 2025.
  • The address inventory is a mix of /23 and /24 blocks, with one distinct /24 block associated with a different registrant and netname.

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: 442 networks and 1,772 prefixes, as published 2026-10-15. 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.
