Summary

Satcom Direct

United States of America · AI-generated

satellite aviation business connectivity

The AS handle SATCOM-DIRECT-INC is held by Satcom Direct Inc.

What it's used for

  • The space carries data center infrastructure, evidenced by the netname SD-DATA-CENTER and reverse DNS pointing to us.zerolayer.net.
  • The inventory consists of 2048 IPv4 addresses within a single prefix, 209.151.208.0/21, with 1 observed neighbour, indicating a small, self-contained network rather than a transit provider.

Notable

  • The registrant SD Data Center aligns with the announcer Satcom Direct Inc., confirming consistent ownership of the address space.
  • Secondary sources indicate that Satcom Direct merged with Gogo, a multi-orbit in-flight connectivity provider, which explains the company's focus on global connectivity solutions for aviation and government sectors.
  • The address inventory is a single /21 block, which is a standard size for a dedicated corporate or data center estate.

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 1,783 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.
