Summary
Siyeh Corporation
business corporate us
SIYEH-ASN-1 is operated by Siyeh Corporation.
What it's used for
- The address space is uniformly registered under the netname
SC-2617with registrantSiyeh Corporationacross all nine announced prefixes. - The AS announces 5632 IPv4 addresses across 9 prefixes and maintains a single observed neighbour, indicating a small, self-contained corporate estate rather than a transit or access network.
Notable
- All registrants in the RDAP data match the AS holder,
Siyeh Corporation, confirming consistent ownership of the inventory. - The inventory consists of a mix of /22, /23, and /24 blocks, including 66.81.140.0/22, 158.62.192.0/22, and 216.122.108.0/22, all located in the United States.
- No IPv6 prefixes are announced, and the reverse DNS sample returned only generic in-addr.arpa entries without specific host identifiers.

Reputation
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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
