Summary

Greystone IT, Inc.

United States of America · AI-generated

business it-services small

GREYSTONE is the AS handle for Greystone IT, Inc.

What it's used for

  • The address space carries business IT infrastructure, evidenced by the netname INAP-WDC002-GREYSTONEIT-66-151-108-0 and the registrant Greystone IT, Inc. for ASHBURN-VA.
  • The AS announces 512 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, a ratio consistent with a small, self-contained business network rather than a transit or large access provider.
  • Traffic from this AS consists of office workers and internal IT endpoints for a small IT services firm, as indicated by the company's profile as an IT solutions provider.

Notable

  • Registrants align with the announcer, with Greystone IT, Inc. listed for the 192.64.200.0/24 prefix and Private Customer for the 66.151.108.0/24 prefix.
  • The address inventory is minimal, consisting of two /24 blocks, one of which is hosted at INAP in Washington, D.C.

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 2026-10-17. 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.
