Unclassified ARIN
Summary
National Cement Company
business corporate cement internal
NATIONAL-CEMENT is the autonomous system for National Cement Company.
What it's used for
- The address space carries corporate infrastructure, evidenced by reverse DNS entries such as
pool-64.nationalcement.com,Office127.corp.nationalcement.com, andvicat-ncc-pool-190.nationalcement.com. - The AS announces 768 IPv4 addresses across 3 prefixes and maintains 4 observed neighbours, a ratio consistent with an internal corporate estate rather than a transit or access provider.
- Traffic from this AS consists of office workers and internal systems for a cement manufacturer operating in the Southeast and Southern California regions.
Notable
- Registrants align with the announcer, including "National Cement Company" and "National Cement IT Department" for the netname
NATIONALCEMENT. - The address inventory is finely subdivided into three /24 blocks, reflecting site-by-site segmentation for a regional industrial corporation.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-01, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
