Summary

Hermes Datacommunications International Limited

United Kingdom · AI-generated

satellite telecom business

HERMES-DATACOMMS is operated by Hermes Datacommunications International Limited.

What it's used for

  • The address space is registered under the netname UK-HERMESDATACOMMS-20110208 for both announced prefixes.
  • The AS announces 512 IPv4 addresses across 2 prefixes with a single observed neighbour, indicating a small, self-contained network rather than a transit provider.
  • Traffic from this AS consists of satellite communications infrastructure and related ICT hardware services, as the company specializes in satellite solutions.

Notable

  • Registrants for both prefixes match the AS holder, listing "Hermes Datacommunications International Limited".
  • The company was acquired by Speedcast International Limited in March 2015.
  • The inventory consists of two /24 blocks: 46.235.0.0/24 and 46.235.3.0/24.

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 1,778 prefixes, as published 2026-10-20. 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.
