Summary

Stonemarche Network CoOp.

United States of America · AI-generated

cooperative business small

The AS handle STONEMARCHE is held by Stonemarche Network CoOp.

What it's used for

  • The address space carries business or organizational traffic, as indicated by the registrant name "Stonemarche Network CoOp." and the secondary registrant "SICA Consulting Services" for the prefix 205.166.65.0/24.
  • The AS announces 512 IPv4 addresses across 2 prefixes with only 1 observed neighbour, a ratio that implies a small, self-contained network rather than a transit or large access provider.

Notable

  • Registrants do not fully agree with the announcer; while 199.89.177.0/24 is registered to Stonemarche Network CoOp., 205.166.65.0/24 is registered to SICA Consulting Services under the netname SCSNH.
  • The address inventory consists of two distinct /24 blocks totaling 512 addresses, with no IPv6 prefixes announced.

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: 453 networks and 1,846 prefixes, as published 2026-11-12. 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.
