AS19816 NCSDATACOM - NCS DataCom, Inc.
Unclassified ARIN
Summary
NCS DataCom
business security enterprise
The AS handle NCSDATACOM is operated by NCS DataCom, Inc.
What it's used for
- The address space is registered under the netname
NCSDATACOM-1for all announced prefixes, indicating a unified corporate estate. - The network announces 8192 IPv4 addresses across 5 prefixes with only 1 observed neighbour, a ratio that suggests an internal corporate or business network rather than a transit provider.
- Reverse DNS evidence includes
ip206-180-165-254.terazero.com, linking the address space to Terazero, a security technology company.
Notable
- All RDAP registrants for the announced prefixes are listed as NCS DataCom, Inc., matching the AS holder.
- NCS DataCom has provided security and business efficiency services since 1987, and the presence of Terazero in reverse DNS suggests a relationship or acquisition involving security infrastructure.
- The inventory consists of five contiguous IPv4 blocks within the 206.180.160.0/21 range, 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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
