Unclassified RIPE
Summary
NRI SecureTechnologies
business security japan
FNCLAB is the AS handle for NRI SecureTechnologies, Ltd.
What it's used for
- The space carries corporate infrastructure, identified by the netname
FNC-NET-CIDR-BLK-JPassigned to both announced prefixes. - The AS announces 512 IPv4 addresses across 2 prefixes with only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
- Traffic from this AS consists of internal corporate endpoints and security operations infrastructure, consistent with NRI SecureTechnologies' business as a provider of cybersecurity services and solutions.
Notable
- The RDAP registrants for both prefixes are listed as Japan Network Information Center; IRT-JPNIC-JP, which is the regional registry (RIR) rather than the end-user organization, while the AS holder is NRI SecureTechnologies, Ltd.
- The address inventory is compact, consisting of two contiguous /24 blocks (192.50.151.0/24 and 192.50.152.0/24) 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: 442 networks and 1,778 prefixes, as published 2026-10-20. 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.
