Summary

Inmarsat Solutions

Netherlands · AI-generated

satellite mobile maritime enterprise

AS-ISOL is operated by Inmarsat Solutions B.V., a provider of global satellite connectivity services.

What it's used for

  • The address space carries satellite broadband and maritime communications, evidenced by netnames such as Inmarsat-BGAN-IP-Range-2, INMARSAT-USA-BGAN, and SEVSAT-US01.
  • The AS announces 26,880 IPv4 addresses across 27 prefixes and 3 IPv6 prefixes, while maintaining only 1 observed neighbour, indicating a dedicated access network for satellite terminals rather than a transit provider.

Notable

  • Registrants include Inmarsat Solutions B.V., Inmarsat Solutions (US) Inc., Inmarsat Solutions Canada Inc, and Ship Equip Inc, reflecting a global corporate structure with regional entities.
  • The address inventory is finely subdivided into numerous /22 and /24 blocks, consistent with an internal corporate estate segmented by service type or geography.

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 1,784 prefixes, as published 2026-10-19. 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.
